Why do teenagers sometimes make outrageous, risky choices? Do they suddenly become reckless, or are they just going through a natural phase? To find out, Kashfia Rahman — winner of the Intel International Science and Engineering Fair (and a Harvard freshman) — designed and conducted an experiment to test how high school students respond to and get used to risk, and how it changes their still-developing brains. What she discovered about risk and decision-making could change how we think about why teens do what they do.

Teenagers are dumb, saw this guy hold himself from one side of a skyscraper.
Edit: he did it once with one hand then died on the next try.
I once saw a teen doing 92 on the freeway on a construction zone. I never saw him again after that.
No, it’s just certain people who don’t do the most intelligent things.

really useful for an 11 min video. Great job.
This the proof that you shape your own brain and design your own reality!
Did it need proof? Is it not or was it never simply common sense?
This is proof that natural forces shape the brain and construct reality for you.
I never did anything stupid as a teen! You can’t judge me!
…looks down at the hefty scar on his knee…
Oh yeah that time…
I did all my stupid crap as a preteen, so I kinda don’t count lmao
I remember Kashfia from the movie/documentary “Science Fair.” There are some amazing kids doing some amazing things out there!
Didn’t study for Math exam. Lemme take this risk!
Hydro oof
1:50 Lets let them choose the most important life decisions then!
yup… sums up what happened to me. regret my decisions to this day
Wow, very well presented by such a young lass. Good talk, interesting topic, glad that Kashfia embraced her curiosity.
Excellent work! I am sure we will be hearing more about in the future.
I wonder if she accounted for peer pressure. Were students already conditioned to think a certain way due to prior experiences before highschool
I’m having the biggest intellectual crush on this girl right now
Bruh she looks like them fucking things where its a person in a small person in a smaller person in a tiny person in a tinyer person
People with disabling fear issues often are caused by parents not allowing their kids to take risks. Very well known you need to expose people to the risks they fear willingly. So they can overcome them. Nothing new here but a great experiment and dedication, keep it up young lady.
