Mark Rober – TEDx Talk TRANSCRIPT
About a year ago, I asked my YouTube followers to play a simple computer programming puzzle that I made with a buddy.
The object of the puzzle was to get your car across the maze by arranging these code blocks that represent typical computer programming operations, such as if-else statements and while loops.
Once you thought you had a good code, you would hit Run, and your car would move based on the commands you had in the program.
I asked my YouTube followers to play it because I said I wanted to prove that anyone from any background could learn to code. 50,000 of them took the challenge and attempted the puzzle.
But the truth was that I didn’t actually care about proving that anyone could learn to code. What they didn’t know is that we actually randomly served up two slightly different versions of the puzzle.
In one version, if you hit Run and you weren’t successful, you didn’t lose any of your starting 200 points. We showed you this message.
[That didn’t work. Please try again.]
However, in the other version, if you hit Run and again you weren’t successful, we showed this slightly different message:
[That didn’t work. You lost 5 points. You now have 195 points. Please try again.]
…stating that you lost five points from your starting 200 points. That was the only difference.
In one version, if you failed, we simply took away five no-value-in-the-real-world, no-one-will-ever-see-these, completely meaningless, fake internet points.
That minor difference is crucial to keep in mind for the results I’m about to show you from the 50,000 data points we collected.
For those who were penalized for failed attempts, their success rate was around 52%. For those who were not penalized, their success rate was 68%.
That statistically significant delta of 16% was really surprising and almost seemed too hard to believe until we looked at another piece of data that we collected, which was attempts to solve before finding success. It’s shown in orange right here.
So, those who didn’t see failing in a negative light nearly had two and a half times more attempts to solve the puzzle. As a result, naturally, they saw more success and therefore learned more.
So if you think about that and sort of unpack these results, the trick to learning more and having more success is finding the right way to frame the learning process.
And this observation seemed really profound to me. It made me wonder: What if you just frame the learning process in such a way that you did not concern yourself with failure, how much more successful could you be, how much more could you learn?
The next thought was that if this is a real effect, clearly there must be some evidence for this in real life. It made me think of toddlers. That’s my boy; I helped make that.
They are constantly trying new things, and they certainly aren’t concerned with failure. When my son learned to walk, he didn’t think about how dumb he might look if he fell down, and as his parents, we didn’t punish him if he wasn’t successful either.
The focus was always on the end goal, and we celebrated the successes with him. As a result of constantly failing and trying and discovering new things during that phase of our life, we discover so many more new capabilities within ourselves. And it’s not even close to any other time in our life.
