Statistics in the Courts: Crash Course Statistics #40 - Duration: 11:18.

Hi, I'm Adriene Hill, and welcome back to Crash Course Statistics.

And sadly, we're nearing the end of this course.

We've covered a LOT of topics.

From probability, to t-tests, to Machine Learning to Bayesian statistics.

Today, we're going to go more "Real World."

We're going to talk about how statistics is used in the courtroom to make...pretty

important...decisions.

In particular, we're going to look at 3 individuals whose lives changed by the use

of statistics: Alfred Dreyfus, Sally Clark, and Jonathan Dorfman.

INTRO

In 1894, a political scandal began in France that would last until 1906 when Alfred Dreyfus--a

Jewish Officer in the French army--was convicted of treason.

His conviction hinged on an unsigned letter--referred to as the bordereau.

The letter offered French military secrets for sale, and the courts decided that it was

Dreyfus who had written it.

Dreyfus was convicted, and for a time, sent to live in a prison cell at Devil's Island.

Which is about as pleasant as the name suggests.

This story is complicated.

Many books have been written about it.

But we'll focus in particular on a handwriting analysis done by Alphonse Bertillon--the founder

of the first crime laboratory for police in France.

Bertillon alleged that Dreyfus purposely made the bordereau look like a forgery of his own

handwriting.

That way, if he ever got caught, he could claim someone had tried to frame him.

Bertillon theorized that Dreyfus created the bordereau by tracing words and letters from

various sources, including one in his own handwriting and his families' handwriting.

That would make the document look more like an forgery than something he'd actually

written.

One of the words Bertillon believed got traced over and over was "intérêt" in Dreyfus's

brother's handwriting.

He'd found a letter written by the brother and thought that the word in that letter looked

similar to some words in the bordereau.

The book Math on Trial: How Numbers Get Used and Abused in the Courtroom breaks down his

process from here.

"Intérêt" contains five of the most commonly used letters in the French language

-- e, n, r, i, and t.

So it would have been a logical one to pick for repeated tracing.

Bertillon created a key to test his theory.

He traced "intérêt" in the brother's handwriting over and over with no spaces on

a line.

This is how he imagined Dreyfus would have created a key of his own:

Conveniently, the bordereau was slightly transparent, so Bertillon could place his key underneath

it, then look for places where letters overlapped.

And yes, there was some overlap, but the majority of letters didn't.

Then, he moved his key over a bit and saw some new overlaps.

(And again, a lot of non-overlap).

But, he got excited by the overlapping letters that he HAD seen, so he decided to make two

keys and put them both underneath the bordereau with a little distance between them.

Then he counted up how many times the letters e,n,r, and t overlapped.

And Bertillon concluded that the letters lined up MUCH more than should be expected by chance.

Which...makes some sense.

I mean he had two keys.

Bertillon used the frequencies of these letters in the bordereau to come up with the expected

frequencies of the overlaps.

So, the bordereau contained about 800 letters and there were about 60 r's.

If his key was just a bunch of R's, then every r in the bordereau would line up with an r

on the key.

But since only 1 out of 7 letters in the key were r's, he expected 1 out of every 7 R's

in the bordereau to overlap with the key by chance.

So, he expected the letter r to line up 9 times.

But it actually lined up 20 times.

All the other letters--with the exception of ê--matched up more times than he expected.

But this logic was suspect.

A group of famous French mathematicians was asked to inspect Bertillon's "analysis."

It didn't hold up.

They went as far as to call it "completely unfortunate"...which is about as mean as

French mathematicians got back then.

The expected probabilities that Bertillon found may have been relatively accurate--but

only when he overlapped the key and the bordereau ONE time.

Bertillon had overlapped them TWICE.

Which means he counted the overlapping letters BOTH in the regular position (red) AND the

offset position (green).

And it was the rebuttal by Three French mathematicians helped finally free Dreyfus.

Our next story starts in England in 1996 when Sally Clark's firstborn son Christopher

had the sniffles.

Doctors told Sally that it was a cold.

But later that month, she found Christopher in distress and called an ambulance.

He later died.

In 1998, Sally's second son, Harry, died in a similar way.

A doctor's examination of Harry found things that could be indicative of abuse, such as

retinal hemorrhaging.

So, an investigation was conducted.

Steve and Sally Clark were arrested for murdering their sons, but Steve was exonerated.

During the trial, Dr. Roy Meadow, a well respected pediatrician, said the probability that one

of Sally's children would die from Sudden Infant Death Syndrome, or SIDS, was 1 in 8,543.

He then made an incredibly consequential probability mistake by declaring that the probability

of TWO of these deaths happening in the same family was 1 in 73 million.

Sally's lawyer confronted Dr. Meadow on whether the probability of Harry's death

was still 1 in 8,543, even though his brother had earlier died with the same diagnosis.

Essentially, he was asking whether these two events were independent or if having one SIDS

related death in a family increases the probability of having another.

And he was right to ask.

SIDS-related deaths in a family may not be independent of each other.

We don't know the cause of SIDS, but if it's even in part genetic or environmental,

it could be possible for babies in the same family to have similar risks.

If Meadow had done the calculation with this in mind, he would have most likely come to

a number MUCH lower than 1 in 73 million.

But that is not the only statistics error that affected the Clark trial.

Whether the lawyers suggested it or the jury assumed it, the unspoken assumption was that

there was only one other option: Murder.

And that since SIDS was so unlikely, murder

MUST be more likely.

The jury sentenced Clark to life in prison for murdering her sons.

But there was another possibility...the deaths could have been caused by naturally occurring

disease or circumstances.

That was found to be the case in Harry's death.

In 2003, Clark's conviction was overturned by a Court of Appeal because Harry's medical

records indicated that he could have been suffering from a Staph infection, which wasn't

disclosed by a pathologist during the original trial.

When we do statistics, we often only consider one, or possibly two different hypotheses.

But it's important to remember that there are other OPTIONS out there.

When possible, we should try to consider those other options.

Otherwise, we can accidentally commit this Prosecutor's fallacy, which incorrectly

claims that since the evidence found is SO unusual or unlikely, that the jury could assume

that the accused defendant isn't innocent.

And secondly, the fact that one hypothesis is unlikely does not mean that another must

be more likely.

Fast forward to 2011, a student at the University of California, San Diego, Jonathan Dorfman,

was accused of cheating on a midterm by his Chemistry professor.

After two Academic Integrity Review Board hearings, Dorfman was expelled from UCSD,

because he had a previous incident on his record.

He then filed a lawsuit against the school.

After the midterm, the professor had noticed that Dorfman had changed the Test Version

on his answer sheet.

There were four versions of the test -- A, B, C, and D. Students were told that if their

test version wasn't the same as the letter on their answer sheet, they should tell their

test proctor.

Dorfman HAD changed the letter on his answer sheet from D

to A. But, he said that he arrived late, so he didn't hear those instructions.

He just saw that his test booklet had a different version than his answer sheet, and changed

the answer sheet to match the test.

After looking at all the exams, the professor also noticed that Dorfman's test matched

another student--they called them Student X--who had test version A, the same one Dorfman

claimed to have.

24 of the 26 answers matched between the two exams.

8 of the 10 incorrectly answered questions, and all 16 of the correct ones.

The professor of the class took this as further proof that Dorfman was cheating, and even

went as far as to get a statistician to say that the probability of those same eight wrong

answers happening by chance was a billion to one.

Though the court documents do not reveal the exact math that the statistician used, it

seems possible that they, like Dr. Meadow in Sally Clark's case, probably assumed

independence when no such assumption should be made.

The wrong answers that students choose aren't always totally random.

On multiple choice tests, many times there's one answer that looks good, even if it's

slightly inaccurate.

And since these students were all taking the same course, and reading the same textbook,

their incorrect answers aren't independent of each other.

Their misconceptions of the material were VERY likely to be dependent on their learning

environment and therefore related.

Dorfman's lawyer displayed this, during the second review board hearing, by showing

44 of the 618 students who took this test (in all its versions) had 23-25 answers matching

Dorfman's.

So this one in a billion stat that was presented to the court can be misleading.

To most people, the stat seems believable at first glance.

And much of the University's initial argument relied on it.

So much so, that they refused to identify Student X--off of whom Dorfman allegedly cheated.

The evidence, they claimed, was so strong that further information about Student X wasn't

required for the case to move forward.

The court determined that by not identifying Student X, the university had given Dorfman

an unfair disadvantage in his hearings.

By not showing who Student X was there was no way to prove that they weren't cooperating

or that they weren't sitting next to each other.

More information about Student X would allow us to update our 1 in a billion chance with

new information, much like we update beliefs in Bayesian Statistics.

Taken alone, the probabilities can be misleading.

The Court ruled in favor of Dorman, saying that if UCSD ever wanted to bring more charges

against him, that they'd need to find Student X.

Many cases are influenced by poor probability calculations.

Understanding basic rules about probability and statistics, and being skeptical of the

probabilities you may hear can have a huge impact on whether or not you come to the right

conclusions.

Thanks for watching, I'll see you next time.

All the material list I will leave in the description of the video ok

I'm going to draw on the back of the eva a dry twig tree I'll leave the mold also in the description

Next I'll trim

Using a brush I'm going to pass the cascorez glue then I'll paste it into the mdf

now i will teach you to make these mini petals with dvd this dvd has already been opened as you can see it is well malleable

cut you will hardly move scissors

you will move more is the dvd for you to quickly form this petals and will end

How is she showing you the video here?

She will stay like this

Now using a very small strip of EVA I'm going to cut some very small boxes like this one

I'm going to stick this part of this little flower here.

in this video today I'm going to use only the cascorez glue

and you'll stick it that way as soon as I'm showing you

Ok, let's go to the next part.

now using the number zero brush

and this ink in black color

I'm going to shade this tree

Detail people look at this pincélio mine is looking like a hook but I'm going to do that work here for you guys anyway

is that I had forgotten to put it soaking in the water so I did my last job and look at what it gave

but let's go there any questions leave in the comments

Also comment if you liked this video

and if you are not registered sign up here on the channel and activate the bell to receive the notifications

and now I'm going to use these two 3D glues in this color remembering that the color is also at your discretion

If you do not want to use it, you do not have any problem

Now using a pen you will put a piece of EVA on top of that tree

then it will mark with the pen and will make the cut

I'll use 3d glue in black to be able to make all the markings

Remembering you can replace with black ink

Unintentionally I ended up excluding the video in which I taught to make the kitten plus his mold will be in the description of the video

then you just go over to the EVA then cut and paste on the mdf

I just spread it with the little brush

making this move then I made with that bigger brush and please people do not ask me also of the eyes that cat because

to my point of view he is looking at the moon so he has his back facing us

and now let's make the famous little bird that I think we all learned in our childhood

I ended up spreading with the brush doing the same movement I just taught you in the beginning today I want to point out to you

the canal pearl max crafts also invite you to know the channel of the Porphyry karina and the channel

beauties of life and arts the link of these channels will be in the description of the video

Classical Musicians React: NCT 127 'Interlude: Regular to Irregular' - Duration: 10:55.

Melissa: I would..whoa! James: Yikes! That's cool.

Umu: This is NCT. Oh boy, oh boy, oh boy, oh boy! Melissa: Non chord tone, 127.

Umu: Well, you're gonna get lots of non chord tones. Oops, spoilers! Melissa: Wow, circle every non chord tone.

James: Eww. Melissa: Take a shot for ever non chord tone. James: No, stop. Oh, my God!

Jordan: So now you're reacting to a b-side track from NCT's 2018 'Regular to Irregular' album.

Elizabeth: Why are those men prettier than I am? What the hell?

This piece is composed by Hitchhiker and Kim Kyung-min. This track, called 'Regular to Irregular':

'Interlude', begins as spoken word over the music of NCT

2018 yearbook number one.

Umu: And the four members, Jungwoo in Korean, Yuta in Japanese, WINWIN in Chinese, and Johnny in English, discuss dreams. Seiji: Yuta?

Japanese guy? Umu: Yeah!

Jordan: And the music switches from tranquil to discordant as the song transitions from the album's themes of 'Regular to

Irregular',

exploring the concepts of dreams and reality. Fiona: Tres, dos, uno.

Elizabeth: Nice repeated piano note. That feels very like

movie music, when something dramatic happens.

Isaac: This is Eric Satie. Kevin: Exactly. It's like Gymnopédie No. 50.

Melissa: Yeah, he really is just speaking.

But like, so softly.

Henry: Wow, his piano playing is very nice.

Elizabeth: That mic must have been so

close. Henry: It's very hot. He was very clear. You can could hear the

sound of his mouth. Elizabeth: The noise in the back of his throat, yeah.

Henry: I kind of like, love that, actually. Elizabeth: No, no, I like it.

It feels very intimate, when you can hear sounds like that.

Stephen: aww! Seiji: Pretty good translation, yeah.

Melissa: Is this in three? I think it's in three.

That's cool. That's new.

Stephen: I mean, not your standard. K-pop song, for sure.

Like, I was expecting like a giant synth pad and something to just like, you know, start pounding four on the floor. Seiji: Waiting for the beat drop.

Maybe it'll happen still.

Isaac: Those shakes, though. Uh, uh, uh, uh. Kevin: I just love the freedom. There's like

no restrictions.

Melissa: Like, I know it's not waltz-like at all,

but like, it feels like it is. Like, you can move to that.

Woo! Low voice.

Lindsey: Their voices are all very calming, also.

Fiona: Their resonance that, with which they sing, their resonant voices, like it comes through in their speaking voices.

Jarod: This is so interesting.

Melissa: That's from that one poem.

James: Ooh! Melissa: Have you read that poem? James: Ooh!

Half steps.

Collin: I actually really like this.

Jarod: I really like this cuz it takes like, the slight rhythmic feel that they had earlier and kind of like, the rhythm is still there,

but obviously the sound is distorted into like,

this. Collin: it's gone

Stephen: Well, there's that beat. Seiji: Yeah, so I guess we were right about the drop. We did get the drop.

Elizabeth: This is Stockhausen!!WAIT!

Henry: It's also the same progression, but recorded backwards.The keyboard playing the same thing underneath, it's the same ??????? material.

Melissa: Whoa!

James: Yikes! That's cool.

This is very dreamlike, it's like that crazy dream that you have

sometimes, where just like, the world's exploding and things are melting, and you're like, oh, my God!

Jarod: Wait, is this it? Collin: What?

That's actually sick.

Whoa!

Jarod: Okay, I... Collin: Shh, shh, wait, it's gonna-

Oh, never mind.

Jarod: I actually really like that.

That was cool, because it's this whole dream concept of regular and irregular.

So it's like, it opens up with this like, you know, really smooth, goopy, sustains

It was very well paced, but there was like a lot of nuance in the playing of the instruments. Like it seemed to just like

slide. It just felt like really, it wasn't like a...

It was very relaxed, and it was like very in time,

but at the same time it really seemed to stretch like they were in no hurry. Like it was really cool, because it creates like that

nebulous dreamscape that one might think of when thinking of a dream, and then it was cool, cuz like he was like speaking on top of

over it. So it kind of added to that kind of atmosphere.

Collin: It sounds like poetry--Jack Kerouac. He'd do that.

He loved jazz, so he would

Like there'd be a jazz band behind him, and because he was famous and he was a good poet,

he would just like read his poetry and they would improvise in according to what was happening in the poetry. Jarod: That's awesome.

Collin: So it is a little bit like that,

yeah. I thought the most valuable thing though, was actually the contrast. At first I didn't like how they were developing,

and I was like no, don't see what I think, cuz I thought it was about to become like this stereotypical like, club beat,

Jarod: Right. Collin: and it was like no, you've done something actually really interesting, but then they ended it.

And it was like, what?!

Jarod: Yeah! I think that's what I really liked about it, because this track is called 'Interlude',

so it kind of serves a greater function in the album. Collin: Yeah.

Melissa: That was crazy. James: I really liked the use of like four different languages, and the

message that it was at least communicating to me was like, yes, we're all dreaming about these different things, but

we're all able to communicate in our own ways about these dreams and even though we're from different cultures and we speak different languages, we

all kind of share this collective kind of experience with like, dreams and what they mean to us.

I thought that was really nice. It was kind of like, oh, made me want to cry a little bit.

Melissa: Aww! James:Yeah, it was really nice. Melissa: Oh, James!

And I loved the duality of like the cello and the violin kind of playing together, and I noticed the first time they came in together

was when one of the guys was talking about,

in his dream, like, you were with me, or like you were there.

He was like talking about someone else. Melissa: Ooh! Text painting! James: Like a lady of some kind, or a man, you know, who knows? But

I just thought that was really nice, and that part at the end was really interesting, too. Melissa: That was lit!

James: It was spooky.

Isaac: What the heck was that?

So we went from Eric Satie, and then we had a nice cello solo, and a very nervous violin,

but it came out fine. Kevin: Mm, hmm.

Kevin: Became nervous. Isaac: Then in the whole like, lavender town. What the heck was that?

Why? I think it does symbolize what they're

transitioning. It's like, from regular to irregular, so you have very nice and simple

dashing melodies, and then later it's just like, very

rough.

Kevin: (speaking Chinese) Isaac: Oh, gosh!

Kevin: I think this song is very creative.

Isaac: Mmm.

Umu: Can you explain in further detail

what Satie and the violet...

Isaac: Well, I was referencing to his gynmonsympathy Kevin: Gymnopédie Isaac: Gymnopédie

Kevin: There you go. Here, piano time!

Kevin: Do you know this piece?

It's a pretty, little, simple piece by Eric Satie, who was a really weird composer. But every time you hear, it's like a nearly waltz,

but it's just one two, one two, and it oscillates between two chords.

That's why this song's connection to Gymnopédie is so strong. Because it starts by oscillating between two chords.

Henry: Wow. I thought that was really cool.

Elizabeth: Yeah, we were just talking about how if you're gonna have very different sections, you have to have something that's the same, and in this case,

they actually took the material from the first section and just reversed it. So you still recognize all of the sounds,

it was just, it felt weird because it was the other way around

Henry: Well, and I didn't even noticed it at first. Good music, you don't notice when there is a single thread going through every single

section. I mean that's like the beauty of you know, like a piece like Brahms 4 or something like that.

Where it like, you know, there's just, there is something that keeps it all tied together. I think it's...what? I think it's great!

Elizabeth: I'm not a Brahms person.

Henry: You play horn.

Elizabeth: Yeah, that's why I'm not a Brahms person.

Henry: I thought that's why you would be a Brahms person. All right,

Elizabeth: Learn every solo in B natural. Do you like transposing by a tritone? Aaagh!

Henry: I think

it was excellent. This piece.

Stephen: I feel like this would be a really great track to put in between two other tracks in a CD.

Seiji: Yeah, it's a good interlude. Umu: Yeah, that's exactly what they did.

They had around like four or five tracks

under the 'Regular' section, and then they smash this one in the middle, and then the rest were under the 'Irregular' section.

Stephen: That's awesome. Wow. Seiji: Yeah, it's a great, it's a story, and the harmony makes it like more

crunchy, and it makes you kind of like get to the edge of your seat a little bit, and then you kind of feel angsty, and then like,

whoo!

And then you have that drop. Super cool.

Stephen: Yeah, one thing I just thought of, its really nice, too,

I feel like the music really reflects thematically what's behind the song. Cuz I mean, I don't know,

I feel like when we all have dreams, sometimes they can be very simple, or almost

naive, in a sense, and I feel like that's reflected where it's just like, oh, you know,

you know, string quartet, just basic 3, 4 waltz.

And then, I feel like, at least hearing this song from that

interpretation, when you kind of see reality in how things aren't always black and white but are more gray,

I feel like that can be reflected in how all of a sudden they distort everything, which is really cool, by the way,

whatever they did, whether or not they used a synthesizer, or used a combination of that, and like distorting the

strings that you were hearing, you could hear how everything was kind of more murky, more unknown, which plays into you know,

real life.

How Sloths Went From the Seas to the Trees - Duration: 12:21.

8 million years ago, off the coast of Peru, a large mammal used its powerful claws to

pull itself along the ocean floor, holding fast against the waves as it foraged for seagrass.

5 million years ago, a similar creature was burrowing underground in Argentina, digging

burrows so massive that you could walk right into one without having to duck your head.

And just 20,000 years ago, another member of this same group of animals climbed the cliffs

as high as skyscrapers, leaving behind the beautifully preserved sheaths of their claws

in caves far above the ground.

But today, the only living relatives of these animals hang upside down from trees.

They poop only once a week, and move so slowly that algae grows on their fur.

But over time, sloths have seen a lot of territory, and their ancestors evolved to fill a really

surprising and diverse array of niches.

The story of sloths is one of astounding ecological variability, with some foraging in the seas,

others living underground, and others still hiding from predators in towering cliffs.

So how did an entire family of burrow-digging, sea-faring, cliff-hopping sloths go extinct,

and their only living relatives end up in the trees?

Well, forgive me for this, but:

Pretty slowly.

Sloths are members of the order Xenarthra, which also includes armadillos and anteaters.

And it's not clear what the last common ancestor of all Xenarthrans was, but genetic studies

of living species suggests that it probably lived more than 65 million years ago.

Which means this early xenarthran lived among the feet of the last non-avian dinosaurs.

But it probably resembled an anteater or an armadillo more than a modern sloth, in that

it was really built for digging.

We know this, because all Xenarthrans share features that are perfect for burrowing.

For example, they all have long, curved claws; and extra contact points between their vertebrae

and their pelvis, which gives them a stiffer lower back to free up their front limbs for

digging.

But since the days of that common ancestor back in the Cretaceous Period, Xenarthrans

have crawled beyond the forest floor and into many other ecosystems.

Sloths have been preserved in the fossil record at least since the early Oligocene, and their

fossil record is huge in South America – representing about 80 to 90 different genera over the last

30 million years.

And many even lived in the same area.

One 17-million-year-old site in Patagonia was home to 11 different genera of sloths

from 3 different subfamilies!

And I mention this because … that's just really strange.

Usually, herbivores of the same size compete with each other for food.

So how did so many sloths live together without competing each other into extinction?

The answers to that question can help us understand why sloths have been been able to occupy so

many niches over time, and why they've been so successful, even to this day.

For one thing, ancient sloths likely had a very low basal metabolism, much like modern

ones do.

That means that when they weren't doing much, they weren't using as much energy

as other mammals of the same size.

This is typical of all xenarthrans, and there's some evidence that it was the case for ancient

sloths.

For example, some research has revealed a relationship between an animal's body temperature

and the amino acids found in its bone collagen.

And a study of fossils of the Shasta Ground Sloth, a giant sloth from the Pleistocene,

found that it probably had a body temp of about 35 degrees celsius.

That's colder than it sounds: If your body fell below 35 degrees, you'd be considered

hypothermic.

Another thing that helped ancient sloths thrive in weird places, and in such large numbers,

is that they could eat all kinds of stuff that no other animals were interested in.

We don't have any fossils of their stomachs, obviously.

But they probably had digestive systems that were just as complex and efficient as modern

sloths', with four chambers, which allowed them to digest tough, fibrous leaves that

other herbivores didn't bother with.

And the last thing that gave these ancient animals an unexpected advantage was in their

mouths.

In both extinct and living sloths, their teeth don't have any enamel, so they aren't

as hard.

But, they're always growing, so sloths can eat pretty much anything without running out

of tooth surface.

So, by having really low metabolism, an efficient gut, and teeth that don't get worn away,

sloths were able to make a good living by specializing in their own favorite hard-to-digest

foods that no one else wanted, so they didn't have to compete with other herbivores, or

each other.

And that knack for picking out resources that nobody else wanted, resulted in some pretty

strange sloths.

Take the sea sloth Thalassocnus.

Which was very hard to say

8 million years ago, in the Late Miocene Epoch, the Peruvian coast was a hot, dry desert without

much food for a large herbivore.

So to make ends meet, an early species of Thalassocnus turned to the sea and the grasses

that grew in the shallow water.

Over the course of about 4 million years, it became more specialized for an aquatic

life, developing denser ribs and limb bones to help weigh it down as it began foraging

in deeper waters.

It also grew in size, eventually becoming as big as a modern sea lion.

Still, Thalassocnus probably wasn't a great swimmer.

Instead of having, say, flippers, it used its big claws to pull itself along the ocean

floor against the force of the crashing waves.

And this, too, was an important adaptation, because those waves were dangerous: Several

fossils of Thalassocnus have been found with broken and re-healed leg bones, signs of trauma

from being swept away and bashed up against the rocks.

But sloths' massive claws allowed them to thrive in other habitats, too.

In Brazil and Argentina, massive burrows reaching up to almost 80 meters long have been found

in Pliocene and Pleistocene rocks.

That's right – rocks, not just dirt.

Some of these burrows are so big that they're practically caves, and giant ground sloths

were the only things around that could dig a hole that big.

We don't know for sure which species managed to engineer these amazing burrows, but it

was probably something like Lestodon

Weighing as much as a small elephant and standing almost 2 meters tall on all fours, Lestodon

was certainly big enough to dig even the biggest of these burrows.

OK, but: How?

Well, even though these sloths were big and slow, they probably didn't have to work

too hard to dig.

These caves are actually found in rock with lots of fissures and faults, so Lestodon and

other sloths likely pulled loose rocks out of the wall, instead of, like, furiously digging.

And once they were done, they had managed to make a useful refuge for themselves.

In addition to providing a safe place to live, the stable climate of the caves probably helped

keep the sloths' body temperatures steady, a big plus when you're, ya know, metabolically-challenged.

But, other sloths lived in caves that they didn't have to dig for themselves.

Take the wee Peruvian sloth with the awesome name of Diabolotherium, or "devil beast,"

from the Late Pleistocene.

Unlike other ground sloths, Diabolotherium had a much greater range of motion in its

elbows and forearms, making it an excellent climber – of rocks.

Its fossils are found almost exclusively in caves, including ones 300 meters up a cliff

face.

And while Diabolotherium was climbing cliffs, there were also other sloths doing what we know

them best for: Living in trees.

As early as the Miocene Epoch, semi-arboreal sloths can be found in the fossil record - like

Hapalops or Nematherium.

Both of them had flexible elbow joints suggest that they could climb trees, and they're

probably ancestral cousins of the modern 2-toed sloth.

But they weren't small like the sloths we know today.

Weighing between 40 and 90 kilograms -- say, from the size of a deer to a kangaroo -- they

could only have been supported by the very biggest branches.

And they definitely didn't hang upside-down.

So sloths have inhabited caves, dived in the seas, lived on the ground, and climbed up

in the trees.

And with their super low metabolism, they were able to find nutrients where others couldn't.

But this brings us to perhaps the weirdest part of the whole story of sloth evolution:

the sloths that survived to the modern day.

Both of the two modern genera of living sloths live in Central and South America.

There are the three-toed sloths, which are members of the genus Bradypus.

And there's the two-toed kind, known as Choloepus.

And they're both are suspensorial.

Which means they spend their time not just in trees, but suspended from trees.

Being suspensorial is basically next-level tree-dwelling, and both tree sloths are so

well adapted to it that, today, that they can barely walk on the ground at all.

But the confusing thing is … there aren't any fossils of suspensorial sloths -- at all!

-- including those of Bradypus or Choelopus.

Which makes it really hard for us to understand their evolutionary story.

And research into their genomes hasn't helped much either, because -- to make things even

stranger -- these two surviving tree sloths don't seem to be very closely related, at

all.

In fact, Choloepus is probably a member of Megalonychidae – a family that included

some pretty big, bad ground sloths - like Megalonyx, which lived in North

America as much as 10 million years ago.

But Bradypus may be the oldest and most primitive member of all sloths, its lineage having split

off from other fossil and modern sloths as much as 30 million years ago.

It's so strange that some paleontologists put it into its own family, all by itself.

So, they come from different ancestral groups, but today's modern sloths both hang from

trees!

Which means that being suspensorial must have evolved twice -- independently -- in each

lineage!

But when you think about it, this tree-hanging lifestyle totally fits with the adaptations

that all sloth ancestors had, just as it did for those that foraged on the sea floor or

lived in cliff caves.

Living the suspensorial life uses less energy, which is great if you have low metabolism,

and those claws that used to be so good for climbing also work perfectly for hanging!

But why are these two small, tree-dwelling sloths the only ones we have left?

Well, after enjoying a good, 20-million year run during the balmy climate of the Miocene

and Pliocene, the giant sloths came face to face with the Ice Age.

Their low metabolism made it harder to be active in the cold.

And for some, their body plans adapted to the cold by becoming larger.

Because big animals are much more resilient to cold temperatures.

This is what happened to the North American ground sloth Megalonyx.

It went from being about 185 kilograms 10 million years ago, to being about a thousand

kilograms just a half a million years ago!

But being big wasn't an advantage when the climate started to warm again.

Their low metabolism meant that sloths couldn't control their internal temperatures very well,

and when the Ice Age ended, the bigger sloths risked overheating if they became too active.

This made it harder for them to survive and reproduce, while also making them easy targets

for predators.

That was especially true in South America, where predators like wolves and jaguars wreaked

havoc on many species, driving many sloths to extinction in the Pliocene and Pleistocene.

Meanwhile in North America, almost all sloths had become really large, and therefore, harder

to cool down.

And at the end of the Pleistocene, hunting by humans may have been an issue on both continents.

But for small, tropical sloths, their combination of a low-energy diet and a suspensorial lifestyle

helped protect them from all of these threats.

So, they may have never been the fastest or most nimble animals.

But over millions of years, sloths have shown an enviable ability to gradually adapt to

environments as diverse as the ocean, hard-rock burrows, and tropical forests.

If evolution is indeed a contest among the fittest, sloths are here to remind us that

slow and steady can still win the race

The Science of Flint's Water Crisis - Duration: 12:17.

[♪ INTRO]

In April of 2014, under the control of an Emergency Manager appointed by the state of

Michigan to help the city through an ongoing financial crisis,

Flint, Michigan switched its water supply.

For decades, the city's water had been piped in from the Detroit Water and Sewerage Department,

which got its water from Lake Huron and treated it.

But in April of 2013, the decision was made to build a pipeline and connect to a new system,

the Karegnondi Water Authority.

This would supply the city with lake water that Flint would treat instead of Detroit,

and was estimated to save 200 million dollars over 25 years.

In the meantime, as a sort of temporary fix while the pipeline was being built, water

would come in from the Flint River and be treated at Flint's water treatment plant.

Now, 4 years after that switch, we know that it damaged hundreds of millions of dollars

of infrastructure, caused deadly bacterial outbreaks that killed at least 12 people,

and exposed thousands of children to high levels of lead in their drinking water.

There are places to learn about the story of how this happened, was covered up, and

was eventually recognized, and the underlying situations that

caused these massive mistakes to be made.

So let's talk about the science of water.

And how something as seemingly simple as a switching to a different water source could

lead to so many bad, but also seemingly unrelated, outcomes.

Humans have actually been using lead pipes in water systems for hundreds of years,

dating back to the ancient Romans.

We eventually moved on to using other materials, like iron.

But in the late 1800s, engineers in the U.S. were all about lead, because lead pipes were

easier to bend around obstacles and were a bit more durable than iron.

People were suffering from lead poisoning, but the public health risks weren't seriously

acknowledged until around the 1920s.

And we gradually stopped making new water pipes from lead.

But in lots of cities in the U.S., like Flint, Michigan, there are still several different

kinds of metals in pipes for water.

In Flint's case, the pipes are made of lead and iron.

The U.S. Environmental Protection Agency didn't have any sort of serious regulation about

lead pipes until the Lead and Copper Rule was enacted in 1991.

It requires regular monitoring and action plans if old lead pipes start becoming dangerous.

So, all that to say, lead water pipes are not that unusual,

a 2016 study estimates that there are still millions in use.

And even though no amount of lead ingested by a human is considered safe,

maybe surprisingly, many of these water systems are usually safe.

A big part of the reason why is anti-corrosion chemicals in the water, like orthophosphate.

Orthophosphate helps lead and some other metal pipes from corroding by forming a compound

that makes a sort of protective layer on the inside of the pipe.

If that layer is patchy or missing, then electron-stealing chemicals called oxidants,

like dissolved oxygen gas, can react with the lead.

And when that happens, the lead will dissolve into the water and contaminate it.

You've probably heard of that.

It's known as leaching, and it's when things get dangerous for people who need this

water to drink or shower or do anything with on their bodies.

Flint, and it is unclear why besides possibly cutting costs, did not add orthophosphate

or any sort of anti-corrosion chemicals when switching to Flint River water.

Even though the treated water from Detroit had had them.

And because Flint was using iron and lead pipes, both iron and lead ended up in the water.

But that's not the whole story.

Not only were these pipes left unprotected, but the water flowing through them also contained

higher than average chloride levels.

Research has found that chloride helps the process of corrosion along.

When there are enough chloride ions in the water compared to some other ions, they start

forming chemical complexes with lead and other atoms.

And these chloride complexes are soluble.

So, basically, it's another way that lead can get into the water.

Part of this too-much-chloride problem was from the river water itself.

Sodium chloride, which is just table salt, would often wash into the river after being

used as a de-icer on roads.

But another part of it had to do with the fact that, a couple of months after the switch

to the Flint River water, there was also a huge bacterial problem.

The river water wasn't just, like, extremely dangerous, though.

We know how to treat water.

We put in disinfectants like chlorine, which can rip open bacteria or mess with the molecules inside them.

But it turns out that chlorine disinfectant can react with metals from corroding pipes,

especially iron, to become completely different

compounds that do absolutely nothing to control bacteria.

So the disinfectants were made useless.

Plus, more chloride ions ended up floating around, which only made the corrosion process worse.

And thus, the vicious cycle escalated.

By August of 2014, there was a city warning that E. coli and other typically gut-dwelling

bacteria, collectively called fecal coliform bacteria,

were thriving in the water and could make people sick.

The Flint treatment plant upped the amount of chlorine they were using to try to kill

off these contaminants.

But because the pipes were already corroding, it wasn't working.

Not only that, but all this extra chlorine they were adding also reacted with some of

the organic chemicals from the river water to form disinfection byproducts called trihalomethanes.

And, researchers have found trihalomethanes to be linked to health problems and even cancer.

So not only was the chlorine turning into a bunch of non-disinfectant chemicals, one

of those was potentially a carcinogen.

Trihalomethanes in the water quickly swelled to above the national regulatory limit.

So to try and fix that problem, the treatment plant added coagulants that would react with

the organic matter in the water to help them filter it out.

Specifically, they used a chemical called ferric chloride.

Which took care of the trihalomethanes,

but meant they were adding even more chloride to the water.

As the pipes got worse and more chlorine was turned into useless compounds,

the elevated bacterial levels became deadly.

Between April 2014 and October 2015, at least 12 people died and 91 people got sick from

an outbreak of Legionnaires' disease, the third largest recorded in U.S. history.

Before the switch to the Flint River water, there were only a handful of cases per year.

Legionnaires' disease is basically a really intense pneumonia.

It's caused by breathing in water-borne bacteria that infect the lungs so they get

inflamed and lead to other symptoms.

This outbreak was caused by a bacterium called Legionella pneumophila, specifically the serogroup

6 strain, which isn't usually detected in the standard urine test for the disease.

After some extensive studies, most researchers agree that this chlorine inactivation at least

played a part in letting these bacteria flourish.

On top of that, some of the experts and investigative journalists

think that there could have been more deaths than were officially confirmed,

because of how tricky it can be to diagnose Legionnaires' disease.

Some deaths caused by these bacterias could have been attributed to pneumonia

in general, and thus not counted.

So, counterintuitive as it might seem, not adding corrosion control also deactivated

the chlorine disinfectant to basically undetectable levels, resulting in tragic loss of life.

In addition to all this, though, there was the ongoing problem of metals leaching into the water supply.

Which we definitely know was because of how the Flint River water was treated.

Because of all these chemical reactions, the process by which lead and other metals got

into the water was not slow and constant.

Sometimes the pipes would leach metal slowly.

But sometimes metal compounds, like the protective layer that wasn't being maintained, flaked

off in little hunks, some of which were even visible to the naked eye.

The leached iron made the water look kind of horrible and taste kind of rusty,

but it isn't a big health concern on its own. Lead is.

But you can't see, smell, or taste it in water.

A single tiny lead flake can take water from safe, to far over the EPA's limit of 15

parts per billion, which requires public action to be taken.

And besides randomly super contaminated samples being right next to uncontaminated samples

because of flakes, the protocols for testing for lead can be manipulated to make it less

likely to record how contaminated the water actually is.

Official EPA protocols for measuring drinking water quality involves letting the water sit

in pipes for at least 6 hours, and then collecting it after a couple minutes.

City protocols called for pre-flushing the pipes for five minutes

before letting them sit for 6 hours.

And, according to experts, this pre-flushing can sweep out initial bursts of lead particles

so they're not in the sample.

Plus, people don't just go turning on their water every once in a while, so those samples

aren't necessarily reflective of what they're using and drinking.

Even still, when the City of Flint tested one resident's water in February and March

of 2015, they found lead levels at 104 ppb and 397 ppb, far above the EPA's action level.

When researchers from Virginia Tech sampled water from the same pipes at low, medium,

and high flow rates, they found levels ranging from 220 ppb to a whopping 13,200 ppb.

And, to be totally clear about how intense this is, a substance with more than 5,000

parts per billion of lead is considered hazardous waste by the EPA.

By September 2015, those same researchers had collected and analyzed 252

water samples from various Flint homes.

101 of the samples had more than 5 ppb of lead.

And they estimated that 90% of homes had a lead level below 25 ppb; 10% were above that.

Which, and I can't say this enough,

was a lot of homes above that 15 parts per billion EPA limit for water.

Protocols matter, y'all!

So that's how metals ended up in the water.

No corrosion control and high corrosive chemical concentrations

exposed many thousands of people to lead poisoning.

And lead poisoning can cause incredibly serious health problems.

Lead interferes with a lot of different enzymes, can cause cells to die, and can slip past

the protective blood-brain barrier to seriously mess with the central nervous system.

We don't know exactly how it interacts with all those systems, but lead ions are chemically

pretty similar to calcium ions, which our bodies use all the time in lots of chemical processes.

So that may have something to do with it.

In any case, it's incredibly detrimental to human bodies and brains,

in adults and especially in children.

All of this was made worse by the fact that the city of Flint has a water system built

to deliver water to over 200,000 people.

Since the population peaked at around that in the 1960s, it has declined to less than half that.

So in some areas, the water moved through some pipes slowly or sat stagnant.

As the Flint River water sat in the pipes and the corrosive chemistry did its thing,

metal concentration rose, disinfectant concentration decreased, and bacterial growth increased.

The city of Flint switched back to piping in treated water from the Detroit water system

in October 2015, after 18 months.

And they're adding in extra phosphate chemicals to try to build up that protective layer again.

But that doesn't just fix the problem that had escalated over that year and a half.

The pipes have already corroded, as have plumbing fixtures and water heaters of many residents.

So while the gradual leaching is hopefully going down, metal flakes may still be chipping off.

Tests show that lead levels are down, and that's great news,

but many residents have also, understandably, lost faith in the

government agencies that are now reporting that the water is safe.

The city is now undergoing a massively expensive process of replacing all of its lead pipes.

A step that was taken to save money has ended up costing far more money than it could have

saved, not to mention lost health, and lost lives.

The way that science was ignored, unknown, or even misused in this story is a lesson

that we all have to live with, and one that we at SciShow hope that we can learn from.

Malia Obama's Boyfriend Comes From A Lot Of Money - Duration: 3:59.

After a couple months acclimating to life at Harvard, pictures of former First Daughter

Malia Obama with a mystery man began to surface, and it looks like things are serious.

Just who is this guy?

Meet Rory Farquharson

Malia Obama began attending Harvard University in the fall of 2017.

Shortly before Thanksgiving, TMZ released a video of Obama briefly locking lips with

someone while tailgating at her very first Harvard-Yale football game.

He's now known to be Malia's rumored boyfriend, Rory Farquharson.

So what's up with Rory?

He's a Brit

The Telegraph reports that Farquharson grew up across the pond and was the so-called "head

boy", class President, essentially, for one year at the prestigious Rugby School, a boarding

school located in the birthplace of the namesake sport.

He was also a member of the chemistry club and played both golf and rugby for the school.

He's a Harvard man

Like Obama, Farquharson is now a student at Harvard University, which is likely where

the lovebirds first met.

While Malia's major is unknown, Farquharson may be following in his father's footsteps,

according to the Telegraph.

Charles Farquharson obtained a law degree from Cambridge University and is now a chief

executive at an investment firm in London.

Rory reportedly followed quite a few banking-related accounts on Twitter before he deleted his

profile.

Which brings us to ...

He's offline

Page Six reported that since he began dating Obama, Farquharson has deleted all of his

social media accounts.

It's understandable given the scrutiny that comes with mega-high-profile relationships.

Just ask Meghan Markle.

According to ABC News, when her relationship with Prince Harry became serious, Markle deleted

her blog, stopped sharing photos of her life on Instagram, and stepped away from Twitter.

Is Rory similarly positioning himself for a long-term commitment?

He's very self-aware

Farquharson didn't mince words when it came time to write a letter to his 16-year-old

self for the Rugby School's publication, Meteor.

In it, he wrote,

"You're a lanky, over-confident public school boy, desperately trying to prove to your friends

how much of a 'lad' you are and have failed miserably."

Farquharson also predicted his near-future, writing:

"You'll have various relationships and constantly meet new people.

You'll even spend time living abroad."

A safe bet, considering he comes from a wealthy family family.

Speaking of which ...

He's loaded

The Farquharsons aren't in the upper crust, but the numbers don't lie: The Telegraph reported

that Farquharson's childhood home in Suffolk is worth just over two million dollars, The

Rugby School cost them 14-thousand dollars per term, and Harvard is, of course, notoriously

expensive.

His executive father isn't the only one bringing home the full English breakfast, either: Rory's

mother, Catherine, is an accountant working for the government in London.

The royal connection

Just because Farquharson is British and rich, that doesn't mean he knows the Queen, right?

Believe it or not, he does have links to the British royal family.

As it turns out, Malia Obama's main squeeze is the second cousin of Andrew Farquharson.

Express reports that Andrew had a lengthy career of working alongside the Queen, first

as her courtier and then as her Assistant Master of the Household at Buckingham Palace.

The Queen even made him a member of her own order of chivalry.

Plus, from 2006 to 2009, Andrew took on a similar role for Prince Charles.

He's a smoker

We don't know much about what brought the two together, but they have one thing in common:

Farquharson and Malia have both been photographed smoking cigarettes.

No word on what Barack thinks about Malia smoking, but in a 2012 interview, Michelle

Obama discussed her husband's former habit as it related to his daughters:

"I know that his ability to ultimately kick the habit was because of the girls, because

they're at the age now where you can't hide.

I think that he didn't want to look his girls in the eye and tell them that they shouldn't

do something that he was still doing."

Doting dad

While President Obama hasn't commented specifically on Malia's relationship, he has discussed

his thoughts about his daughters growing up and dating.

A few months before Malia and Rory were spotted locking lips, ABC News asked him how he felt

about his girls dating.

Obama said he's, quote, "pretty relaxed about it," citing Michelle's influence as one reason

he's so chill about the prospect.

Then Obama joked:

"The other reason is because they've had secret service.

There's only so much they can do!"

It's unclear if Malia is still under secret service protection, and if this protection

is why Farquharson deleted his social media accounts.

Regardless, the whole world's watching their every move, the price you pay for mingling

with American royalty.

Demisexuality - Duration: 4:20.

Do you know what sexual orientation isn't talked about much but describes a valid and

prominent subgroup of our community?

Demisexuality.

[WHIP CRACKING, COUGH]

Demisexuality is a newer label to help describe people's experience of being somewhere between

asexual (not experiencing sexual attraction) and zed- or allosexual (experiencing it).

The prefix demi, meaning divided in half, is a little of both.

In this book, The ABC's of LGBT+, Ash Hardell explains, "the most common definition of

demisexuality or demiromanticism is an orientation in which a person only experiences attraction

to people with whom they have formed a strong emotional bond."

In other words, attraction to strangers typically doesn't happen.

It is possible to be a combination of identities also known as compound sexual orientations.

Humans are diverse.

Maybe this helps:

Demisexuality forums have a model that distinguishes between primary and secondary sexual attraction.

Primary sexual attraction is being drawn to someone from the first impression (their appearance,

their smell).

You meet them and you think, "Yep, I wanna have sex with this person."

It's lust at first site.

Secondary sexual attraction happens after getting to know the person well and being

comfortable with them.

A non-sexual relationship develops and then maybe there's interest in becoming sexual.

This could take hours, weeks, months, or years -- really whatever time is needed to form

a deep emotional connection that sparks desire (and sometimes that's never).

Sound like you?

You can identify as demi.

Demisexuality (like demiromanticism) encompasses a spectrum of experiences within it, and one

of them can be yours.

There's a strong but not exclusive need for emotional intimacy at one end of the spectrum.

And a sort of

asexuality-in-behavior-tinted-demisexual-from-the-belief-or-experience-that-sexual-attraction-is-possible-under-certain-conditions

at the other.

The Asexual Visibility and Education Network actually coined the term demisexual in 2008

to express this subtle difference.

Demisexuality is often considered part of an asexual spectrum, a type of gray-asexuality

where people might identify as gray ace, gray a, or grace.

Gray for in between - not experiencing sexual attraction to the degree expected by one's society,

but experiencing some sexual attraction sometimes or under specific circumstances.

To show the similarity and overlap, these are the asexual and demisexual flags.

Black in both of them represents lack of sexual attraction, gray is for the gray-asexual

identities, and purple symbolizes community.

Aside from the white in the demisexuality flag for the existence of sexual attraction

in some situations, they're like fraternal twins.

Now you might ask, "But isn't that just having standards?

Doesn't this apply to everyone who cares about knowing the person they're hooking

up with first?"

No.

Having criteria for who you do or don't wanna have sex with is a choice.

For example, you might choose to trust a person before having sex.

For demisexuals -- it's not a choice.

(It's a sexual orientation and sexual orientation isn't. a. choice.)

When demisexuals recount their experiences with sexual attraction, they sound like asexuals

who can't relate to the social norms of wanting to get into someone's pants, having

crushes, striving to get laid, making-out at parties, hooking-up with friends, gossiping

about hot celebrities, the stirring in the loins... except under rare circumstances.

Demisexuality is more like asexuality with flexibility, than allo or zedsexuality with preferences.

Here are some sentiments from that people who identify as demisexual or demiromantic.

"I'm not better or more 'pure' because my relationships are based on romantic attraction."

"Demisexuality is real, and not a phase."

"I've had a lot of people dismiss my demisexuality as a sign of prudeness or abuse."

"Not all demisexual people are repulsed by sex."

"A lack of sexual intimacy in a relationship does not indicate a lack of emotional bonds."

"People assume I'm not sexually active because I'm trans.

They assume that my dysphoria would get in the way.

I'm a virgin because I'm demisexual and haven't found someone I want to have sex with."

"My sexuality is validated.

It reminds me that I'm not alone, that I am seen, and that it's okay to be me."

"There are communities of demi and ace people who are ready to welcome you with open arms."

There's a link to a demisexual playlist that I've curated and links to other resources

to learn more in the description.

Stay curious.

How kids can help design cities | Mara Mintzer - Duration: 14:25.

Our society routinely makes decisions

without consulting a quarter of the population.

We're making choices about land use, energy production and natural resources

without the ideas and experiences of the full community.

The car, an inanimate object, has more say over public policy

than this group of citizens.

Can you guess which group I'm talking about?

It's children.

I work in urban design, and not surprisingly,

most cities are designed by adults.

Urban planners, architects, developers, politicians,

and occasionally, a few loud citizens.

Rarely do you consider the voices of a group of four-year-olds,

barely tall enough to reach the podium at city council chambers.

But today, I want to ask you this:

What would happen if we asked children to design our cities?

(Laughter)

Back in 2009, I was introduced to a small group of people

who wanted to start a child-friendly city initiative in Boulder, Colorado.

I come from a family of civil rights advocates,

and I had spent my career until that point

working with low-income children and families.

But I had never heard of a child-friendly city initiative before.

So I figured its purpose would be to address some of the frustrations

I had encountered as the parent of a young child.

Perhaps we would advocate for more changing tables in restaurants.

Or create indoor play spaces for those cold and rainy days.

In other words, make the city more hospitable to children and families.

It wasn't until after I committed to this project

that I realized I had it all wrong.

We wouldn't be designing better cities for children.

Children would be designing better cities for themselves,

and for the rest of us, too.

Now, I bet you're skeptical about this idea.

And honestly, I was, too.

I mean, there must be a reason the voting age is 18.

(Laughter)

How could children possibly understand complex ideas

such as the affordable housing crisis

or how to develop a transportation master plan?

And even if they had ideas, wouldn't they be childish?

Or unreasonable?

Do our cities really need a park made out of candy?

(Laughter)

Or a bridge with water cannons

that fire water onto unsuspecting kayakers below?

(Laughter)

While these concerns sound legitimate,

I realized that not including children in city planning

was a bigger design problem.

After all, shouldn't we include end users in the design process?

If we're building a park to be largely used by kids,

then kids should have a say in the park's design.

So with all of this in mind,

we formed a program called "Growing Up Boulder,"

and my job is to work with children ages zero through 18

to come up with innovative city-design solutions.

How do we do this, you might ask?

Let me give you a real example.

In 2012, the city of Boulder decided to redesign a large downtown park,

known as the Civic Area.

This space is bounded by a farmers' market on one end,

Boulder Public Library on the other end,

and by Boulder Creek, which runs through the middle.

The space needed a new design

to better handle the creek's inevitable flash floods,

restore a sense of safety to the area

and support an expanded farmers' market.

So from 2012 through 2014,

we engaged more than 200 young people in the process,

ranging from preschool through high school students.

Now, how did we do this?

Let me explain.

First, we visited children in their classrooms

and presented the project:

what it was, why their ideas mattered

and what would happen with their recommendations.

Before we could influence them, we asked children to record their ideas,

based on their own lived experiences.

Then we asked children to go on a field trip with us,

to document what they liked and didn't like about the space,

using photography.

Through green picture frames,

students highlighted what they liked about the space,

such as college students, tubing down the creek.

(Laughter)

Then they flipped those frames over and used the red side

to highlight things they didn't like, such as trash.

Our sixth-grade students studied the Civic Area

by researching sites with similar challenges

from around the world.

Then, we invited the kids to combine their original ideas

with their new inspiration,

to synthesize solutions to improve the space.

Each class invited adult planners, city council and community members

into the classroom, to share and discuss their recommendations.

Boulder's senior urban planners stepped over blocks and stuffed animals

to explore preschool students' full-size classroom recreation of the Civic Area.

Adult planners marveled at the students' ideas

as they shared a park constructed out of a jelly bracelet.

It was supposed to be an ice-skating rink.

And then, public art constructed from animal-shaped plastic beads.

And while this may seem ridiculous,

it isn't so different from the models that architects create.

Now, fast-forward four years, and I am pleased to report

that many of the children's ideas are being implemented in the Civic Area.

For example,

there will be improved access to Boulder Creek,

so kids can play safely in the water.

Lighting in previously dark underpasses,

so high school students can walk home safely after school at night.

And separated biking and walking paths,

so speeding bikers won't hit young people as they stroll by the creek.

My daughter and I even skated on a new, child-requested ice-skating rink,

last winter.

So, were all of the kids' ideas implemented at the Civic Area?

Of course not.

Democracy is a messy process.

But just as a reasonable and well-informed adult

does not expect all of her ideas to be utilized,

neither does a nine-year-old.

We've now been using this process for eight years,

and along the way, we've found some incredible benefits

to designing cities with children.

First of all, kids think differently from adults.

And that's a good thing.

Adults think about constraints,

how much time will a project take,

how much money will it cost and how dangerous will it be.

In other words, "Are we going to get sued?"

(Laughter)

It's not that these constraints aren't real,

but if we kill off ideas from the beginning,

it limits our creativity and dampens the design process.

Kids, on the other hand, think about possibilities.

For kids, the sky is the limit.

Literally.

When we worked with middle-school students to design teen-friendly parks,

they drew pictures of skydiving, hang gliding,

(Laughter)

and jumping from trampolines into giant foam pits.

(Laughter)

Some of this sounds far-fetched,

but the commonalities among the activities revealed an important story.

Our adolescents wanted thrill-seeking opportunities.

Which makes perfect sense, given their developmental stage in life.

So our task, as connectors between inspiration and reality,

was to point them towards activities and equipment

that actually could be installed in a park.

This is exactly what parks in Australia have done,

with their extensive zip lines and their 30-foot-tall climbing towers.

When kids dream up a space,

they almost always include fun, play and movement in their designs.

Now, this is not what adults prioritize.

But research shows that fun, play and movement

are exactly what adults need to stay healthy, too.

(Laughter)

Who wouldn't enjoy a tree house containing a little lending library

and comfortable beanbag chairs for reading?

Or what about a public art display

that sprays paint onto a canvas each time you walk up the steps?

In addition to fun and play, children value beauty in their designs.

When tasked with designing dense affordable housing,

kids rejected the blocks of identical, beige condominiums

so many developers favor,

and instead, put bright colors on everything,

from housing to play equipment.

They placed flowers between biking and walking paths,

and placed benches along the creek,

so kids could hang out with their friends

and enjoy the tranquility of the water.

Which leads me to nature.

Children have a biological need to connect with nature,

and this shows up in their designs.

They want nature right in their backyards,

not four blocks away.

So they design communities that incorporate water,

fruit trees, flowers and animals into their common spaces on site.

For better or worse, this is logical,

because five-year-olds today are rarely allowed to walk four blocks

to access a park by themselves.

And nature in one's immediate environment benefits everyone,

since it has been shown to have restorative effects for all ages.

It may come as a surprise,

but we even take into consideration the desires or our littlest citizens,

babies and toddlers.

From toddlers, we learned that the joy of walking

comes from what you discover along the way.

When they evaluated the walkability of Boulder's 19th Street corridor,

toddlers spent long stretches exploring leaves in a ditch

and sparkles in the sidewalk.

They reminded us to slow down

and design a path where the journey is as important as the destination.

In addition to trees and plants,

kids almost always include animals in their designs.

Insects, birds and small mammals

figure prominently into children's pictures.

Whether it's because they're closer to the ground

and can see the grasshoppers better than we can,

or simply because they have a greater sense of empathy for other beings,

children almost always include non-human species in their ideal worlds.

Across the board, children are inclusive in their city planning.

They design for everyone, from their grandmother in a wheelchair

to the homeless woman they see sleeping in the park.

Children design for living creatures,

not for cars, egos or corporations.

The last and perhaps most compelling discovery we made

is that a city friendly to children is a city friendly to all.

Bogota, Colombia mayor Enrique Peñalosa

observed that children are a kind of indicator species.

If we can build a successful city for children,

we will have a successful city for all people.

Think about it.

Kids can't just hop in a car and drive to the store.

And most kids can't afford an expensive lunch at the nearby cafe.

So if we build cities that take into the consideration

their needs for alternative forms of transportation

and for cheaper food venues,

we meet the needs of many other populations, too.

The more frequent and more affordable bus service,

so desired by our youth,

also supports the elderly who wish to live independently,

after they can no longer drive cars.

Teens' recommendations for smooth, protected walking and skateboarding paths

also support the person in a wheelchair who wishes to go smoothly down the path,

or the parent pushing a new stroller.

So to me, all of this has revealed something important.

An important blind spot.

If we aren't including children in our planning,

who else aren't we including?

Are we listening to people of color, immigrants,

the elderly and people with disabilities, or with reduced incomes?

What innovative design solutions are we overlooking,

because we aren't hearing the voices of the full community?

We can't possibly know the needs and wants of other people

without asking.

That goes for kids and for everyone else.

So, adults, let's stop thinking of our children as future citizens

and instead, start valuing them for the citizens they are today.

Because our children

are designing the cities that will make us happier and healthier.

Cities filled with nature, play, movement, social connection and beauty.

Children are designing the cities we all want to live in.

Thank you.

(Applause)
