“Cognitive Ability and Conscientiousness Are More Important Than SES for Educational Attainment: An Analysis of the UK Millennium Cohort Study”, Michael O’Connell, Gary N. Marks2022-04-01 (, ; similar)⁠:

The influences on children’s success in education remain a profoundly important topic of enquiry. The dominant view is that socioeconomic background (SES) is critical.

This study examines the influences on student performance in the General Certificate of School Education (GSCE) taken at age 16 in England, Wales and Northern Ireland analysing data from the Millennium Cohort Study. The GSCE results of 8,303 students were converted to a numerical score.

2 psychological factors—cognitive ability and their level of Conscientiousness—could explain almost as much of the variation in exam attainment as all measures, and far more than a model of socio-economic factors.

The power of psychological traits in influencing key educational outcomes is underestimated.
