Subclaims¶

q2 i? PGSs were positively associated with reading and speaking skills in early childhood, subsequent scholastic achievement, and an index of economic security in adulthood. → David Cesarini and Peter M. Visscher 2017 q2 i? About half the effect of the PGS on adult outcomes was mediated by measured cognitive and noncognitive skills. → David Cesarini and Peter M. Visscher 2017 (2)

q2 · i? · review · r3

The review reports, citing a study with rich phenotypic data tracking individuals up to four decades, that PGSs were "positively associated with reading and speaking skills in early childhood, subsequent scholastic achievement, and an index of economic security in adulthood".

"The study reported that PGSs were positively associated with reading and speaking skills in early childhood, subsequent scholastic achievement, and an index of economic security in adulthood."

Same study as reported by the review: a mediation analysis found "about half the effect of the PGS on the adult outcomes was mediated by measured cognitive and noncognitive skills".

"A mediaton analysis revealed that about half the effect of the PGS on the adult outcomes was mediated by measured cognitive and noncognitive skills."
