"Imputation of fluid intelligence boosts gene discovery power" — Nature Genetics · Science & Medicine
This study demonstrates that statistically imputing scores—using available cognitive and demographic data—for participants in large biobanks like UK Biobank can substantially increase the effective sample size for genetic analyses. This reduces ascertainment bias (since cognitive test takers are not representative) and boosts the statistical power to detect genetic variants associated with fluid intelligence. The paper presents validation of the imputation method and shows improved gene discovery in genome-wide association studies.
The claim is directly from a peer-reviewed research article published in Nature Genetics, a leading journal. The study provides empirical evidence for the imputation method's effectiveness, including validation against real data. As a primary source, the paper itself is the authoritative report of the findings.
Genuinely new; the paper was published on October 20, 2026.
