Simple, easy to understand, easy to apply: Researchers said the test indicated the likelihood of a child’s future success. Higher SAT scores. Better social skills. Less likelihood of obesity and substance abuse. Delaying gratification — holding out while the researcher left the room and not eating the first marshmallow — was the reason those kids turned out to be more successful.
The original study followed approximately 90 kids who were all enrolled in a preschool on the Stanford campus (conveniently for the Stanford researcher.) A new, larger study — involving kids from a much broader range of races, ethnicities, parent backgrounds, etc. — reveals that kids who wait to get two marshmallows instead of giving in and eating the first one tend to come from wealthier households.
