Self-discipline gives girls the edge: Gender in self-discipline, grades, and achievement test scores.
Abstract
Throughout elementary, middle, and high school, girls earn higher grades than boys in all major subjects. Girls, however, do not outperform boys on achievement or IQ tests. To date, explanations for the underprediction of girls' GPAs by standardized tests have focused on gender differences favoring boys on such tests. The authors' investigation suggests an additional explanation: Girls are more self-disciplined, and this advantage is more relevant to report card grades than to achievement or aptitude tests. Eighth-grade girls at an urban magnet school were more self-disciplined than their male counterparts according to delay of gratification measures and self-report, teacher, and parent ratings. Whereas girls earned higher grades in all courses, they did only marginally better on an achievement test and worse on an IQ test. Mediation analyses suggested girls earned higher GPAs at least in part because they were more self-disciplined.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
