0:00:14.380,0:00:17.868
You have just been subjected[br]to a scientific experiment.

0:00:19.000,0:00:20.209
Ha, ha, ha!

0:00:22.209,0:00:27.209
We are trying to pose a question[br]and the question here was:

0:00:27.250,0:00:32.168
What is the best strategy[br]to solve this kind of problems?

0:00:33.375,0:00:37.333
You all solved two problems,[br]on sheet number 1 and 3,

0:00:37.334,0:00:41.417
but different things happened[br]for each of you on sheet 2.

0:00:42.459,0:00:48.043
We offered some of you a possible strategy[br]to solve this kind of problems.

0:00:48.083,0:00:51.333
We told you how you can[br]think this problem.

0:00:51.334,0:00:56.416
We asked others to think[br]how they solved the first problem.

0:00:56.417,0:01:01.584
To reflect: what methodology did you use?[br]How did you face the problem?

0:01:01.584,0:01:06.666
To the third group among you[br]we asked you to just relax,

0:01:06.667,0:01:10.876
to close your eyes, breathe,[br]and calm down for a while.

0:01:11.501,0:01:13.960
And then, you all solved[br]the second problem.

0:01:15.292,0:01:17.751
The question we want to answer is:

0:01:17.792,0:01:21.543
which of these 3 groups was better[br]at solving the second problem?

0:01:23.292,0:01:29.043
Which of these three possible strategies[br]is better to solve these problems.

0:01:30.042,0:01:31.082
Isn't it great?

0:01:31.083,0:01:32.458
(Laughter)

0:01:32.459,0:01:33.668
I love this.

0:01:33.709,0:01:35.876
(Applause)

0:01:39.167,0:01:43.875
Imagine teachers, with all that passion,

0:01:43.876,0:01:47.750
that energy, that wisdom, and experience,

0:01:47.751,0:01:51.082
if we could provide them[br]with a scientific view

0:01:51.083,0:01:53.250
of what works and what doesn't.

0:01:53.250,0:01:55.667
Which things work better than others.

0:01:55.709,0:02:00.208
And it's not that difficult,[br]we just did it in 10 minutes.

0:02:00.209,0:02:03.168
It's going to take us a couple[br]of weeks to process all this,

0:02:03.169,0:02:04.792
but it wasn't that long.

0:02:07.250,0:02:11.375
We hypothesize which may be the answer.

0:02:11.417,0:02:14.249
Our hypothesis is that perhaps

0:02:14.250,0:02:19.292
to reflect on how we solved[br]the problem the first time,

0:02:19.292,0:02:25.043
can make us better to solve[br]a similar problem the second time.

0:02:26.292,0:02:30.626
But the truth is, the answer is:[br]we do not know.

0:02:31.417,0:02:36.626
And that is what's great about[br]this type of scientific experiments.

0:02:36.626,0:02:41.458
It let us ask questions on things[br]that are very important for us,

0:02:41.459,0:02:44.001
but for which we don't know the answer.

0:02:45.584,0:02:47.958
This is the idea of what we do.

0:02:47.959,0:02:49.958
We call it TEDxperiments,

0:02:49.959,0:02:52.958
it's something we started[br]two years ago in this same room,

0:02:52.959,0:02:57.333
and we already did TEDxperiments[br]in two TEDxRíodelaPlata events.

0:02:57.334,0:03:00.082
This is the fifth experiment we'll do,

0:03:00.083,0:03:03.875
and within a few weeks[br]we're going to share the results.

0:03:03.876,0:03:05.627
But let me show you...

0:03:07.584,0:03:11.166
some things that happened two years ago.

0:03:11.167,0:03:15.958
We did an experiment where we wanted[br]to see what was the effect

0:03:15.959,0:03:18.001
when one person tells another one

0:03:18.002,0:03:21.667
something that is important to the former,[br]and the latter doesn't care.

0:03:22.486,0:03:24.656
I don't know if this ever happened to you.

0:03:24.657,0:03:25.807
(Laughter)

0:03:26.751,0:03:30.793
Then we did the following: we handed them[br]out envelopes like we did today.

0:03:30.794,0:03:34.249
To the odd rows,[br]the note in the envelope said,

0:03:34.250,0:03:38.876
"You are going to tell a story[br]that is important in your lives."

0:03:38.876,0:03:41.374
While the even rows were instructed,

0:03:41.375,0:03:45.167
"You will listen," but not the same way[br]to everyone like today.

0:03:45.168,0:03:48.041
Some had to pay a lot of attention,

0:03:48.042,0:03:51.374
not to take their eyes off the person.

0:03:51.375,0:03:55.625
The others were asked[br]to totally ignore them,

0:03:55.626,0:03:59.166
to check their cellphones,[br]to do other things, etc.

0:03:59.167,0:04:01.334
And after that we asked questions.

0:04:01.334,0:04:04.168
"What did you feel?"[br]"About your own story?"

0:04:04.169,0:04:06.376
"How's your self-esteem?" and such things.

0:04:06.377,0:04:08.042
And amazing things happened.

0:04:08.043,0:04:12.292
In particular, around that row,[br]there was a lady sitting.

0:04:12.334,0:04:15.417
She attended the event with her daughter[br]and her grandchildren.

0:04:16.041,0:04:17.918
And she had to tell a story.

0:04:17.918,0:04:21.418
The person in the back row[br]she was telling the story to,

0:04:21.420,0:04:25.416
was a boy of 12 she didn't met before.

0:04:25.417,0:04:28.500
And his instructions were to ignore her.

0:04:30.125,0:04:32.791
She began her story passionately,

0:04:32.792,0:04:36.792
she was moved by her own history,[br]but this kid wasn't caring at all.

0:04:36.793,0:04:37.955
(Laughter)

0:04:39.209,0:04:43.376
He began to feel bad about himself[br]because he had this contradiction,

0:04:43.377,0:04:46.834
he was listening to the story[br]and beginning to be moved by it,

0:04:46.834,0:04:49.168
but he wanted to follow the rules as well.

0:04:49.876,0:04:52.835
The rest of the four minutes[br]were very uncomfortable.

0:04:52.836,0:04:56.710
She obviously didn't know[br]he had to follow this instruction.

0:04:56.711,0:05:01.751
She hated him, he hated himself,

0:05:01.751,0:05:09.249
the 4 minutes were over[br]and when we revealed what had happened,

0:05:09.250,0:05:13.084
she turned around, they hugged,[br]and they both started to cry.

0:05:14.876,0:05:17.168
An interesting thing of this experiment

0:05:17.169,0:05:20.751
is that of all the experiments[br]we did so far, it was the first one

0:05:20.751,0:05:22.418
where we found something new,

0:05:22.419,0:05:25.584
something the scientific community[br]didn't know about.

0:05:26.584,0:05:29.085
This is not a game,[br]we are creating knowledge.

0:05:29.086,0:05:31.709
And we sent it for publication.

0:05:31.709,0:05:37.374
It was just accepted in a worldwide,[br]top notch science magazine,

0:05:37.375,0:05:41.334
and this is the article's title[br]that will soon be published;

0:05:41.335,0:05:44.583
and the TEDxperiments team published it.

0:05:44.584,0:05:46.876
Let's give it to them because it is...

0:05:47.544,0:05:48.835
(Applause)

0:05:57.959,0:05:59.751
The title is a bit cryptic, right?

0:05:59.752,0:06:04.625
It's in English, so I said, well,[br]what if we typed it in the browser...

0:06:04.626,0:06:06.626
[Google Translator][br](Laughter)

0:06:07.792,0:06:12.084
And when I typed it in the Translator,[br]something like this read,

0:06:12.085,0:06:14.333
[It bothers me that you check your phone

0:06:14.334,0:06:16.501
and don't pay me attention[br]when I'm talking.]

0:06:16.501,0:06:17.793
(Laughter)[br](Applause)

0:06:24.959,0:06:28.452
Last year, when we held our event[br]in October, that very, very large event,

0:06:28.452,0:06:30.208
the world's largest TEDx,

0:06:30.209,0:06:33.168
we did another experiment,[br]this time, with 10,000 people.

0:06:33.169,0:06:37.793
We asked all these 10,000 people[br]to play thumb wars in couples.

0:06:38.792,0:06:42.209
Sometimes with eyes closed,[br]and we'd give them different instructions.

0:06:42.210,0:06:44.501
And we wanted to test

0:06:44.501,0:06:48.416
our capacity to cooperate vs. to compete.

0:06:48.417,0:06:54.208
If we are able to cooperate or not,[br]when cooperation is the best strategy.

0:06:54.209,0:06:56.043
And it turns out that, in many cases,

0:06:56.044,0:06:58.958
we end up competing when it's unnecessary,

0:06:58.959,0:07:01.958
when the best for all is to collaborate.

0:07:01.959,0:07:04.541
And that also gave a result[br]that is being processed,

0:07:04.542,0:07:07.168
and it will probably, hopefully,[br]become another article

0:07:07.169,0:07:10.542
that will contribute to human knowledge.

0:07:11.459,0:07:15.791
But here so far, we were keeping the data.

0:07:15.792,0:07:18.333
Now we decided to launch this.

0:07:18.334,0:07:22.208
And the TEDxperiments website[br]went online today.

0:07:22.209,0:07:24.958
The idea of this site is to make public

0:07:24.959,0:07:28.833
the results of all the experiments[br]we did so far.

0:07:28.834,0:07:32.041
Of the 4 we did until yesterday,[br]3 were already uploaded,

0:07:32.042,0:07:33.908
the fourth will be uploaded there soon.

0:07:33.908,0:07:38.583
And you can see it in:[br]tedxriodelaplata.org/tedxperiments

0:07:38.584,0:07:41.543
today when you come back home.

0:07:43.083,0:07:49.082
This fills me with joy[br]because we believe that in these events

0:07:49.083,0:07:51.542
is good to come and listen[br]to ideas and learn;

0:07:51.542,0:07:55.084
maybe sometimes we have a new idea[br]when we listen to other ideas.

0:07:55.085,0:07:58.792
But given the amazing community we are,

0:07:58.794,0:08:00.780
why not also create new knowledge?

0:08:00.792,0:08:03.791
Knowledge that is relevant,[br]in this case for education;

0:08:03.792,0:08:06.334
for how we communicate and how we relate.

0:08:06.335,0:08:12.041
I invite you all to have[br]a critical eye, to ask questions,

0:08:12.042,0:08:16.125
and to try to validate them[br]in a way they become irrefutable.

0:08:16.126,0:08:21.208
So they can help others learn[br]and teach in a different way.

0:08:21.210,0:08:22.755
Thank you.

0:08:22.756,0:08:24.246
(Applause)
