The Second Marshmallow

I’m not sure how this is germane to David Brooks’ new book, or to the reviewer’s critique of it, but I find it fascinating nonetheless:

And a famous experiment conducted around 1970 demonstrated that the ability of 4-year-olds to postpone gratification by leaving a marshmallow uneaten for a time as a condition of receiving a second marshmallow was a very good predictor of success in life: “The kids who could wait a full 15 minutes had, 13 years later, SAT scores that were 210 points higher than the kids who could wait only 30 seconds. . . . Twenty years later, they had much higher college-completion rates, and 30 years later, they had much higher incomes. The kids who could not wait at all had much higher incarceration rates. They were much more likely to suffer from drug- and alcohol-addiction problems.”

I think I would have been a single marshmallow guy, no matter what the consequences.
