In a study, scientists could predict a kid's future academic achievements thanks to a marshmallow!

The Stanford marshmallow experiment were a series of studies on delayed gratification in the late 1960s and early 1970s.

In these studies, a child was offered a choice between one small reward (sometimes a marshmallow, but often a cookie or a pretzel, etc.)

Provided immediately or two small rewards if he or she waited until the experimenter returned (after an absence of approximately 15 minutes).

The results showed that the number of seconds a four year old is able to resist eating a marshmallow is a reliable predictor of their later academic and job performance.

Those who resist the longest tend to have the highest GPAs and SAT scores, get into the best colleges, and have the best job outlooks.
