Mind

The Stanford marshmallow test was once treated as a window into a child’s self-control. But a University of Rochester experiment found that children who had just watched an adult break promises waited only three minutes, while those who had seen the adult keep them waited 12—suggesting the test measured whether waiting seemed rational, not willpower alone.

Children waited four times longer after an adult kept two promises, showing that the marshmallow task blends self-regulation with a rational estimate of reliability.
