What happens when you give a group of four year olds a marshmallow each and tell them not to eat it?
In this talk Joachim de Posada recaps the result of the famous experiment which shows two thirds of children will eat the treat, even with the promise of a second marshmallow within 15 minutes if they abstain. Of the remaining children, 100% are successful at the age of 18, proving the point that delayed gratification and self discipline leads to success.
And if you ever wondered whether Hispanic kids behaved the same way, de Posada has some humorous videos to prove they do.
