Read the original paper, though, and the popular myth starts to crack. What the 1972 Mischel experiment actually showed (waiting is a matter of strategy), the surprisingly small sample behind the famous long-term correlations, and what happened in 2018 when the Watts team reran the test with about 900 children and the effect shrank sharply once family background was controlled — the first installment of Psychology, Straight from the Papers.
