R0007/2026-03-19/C001¶
Claim: O'Boyle and Aguinis (2012) studied five studies, 198 samples, 633,263 individuals across researchers, entertainers, politicians, and athletes and found individual performance follows a power-law distribution, not a normal distribution. The top decile produces roughly 30% of total output; the top quartile produces over 50%.
BLUF: The study parameters (five studies, 198 samples, 633,263 individuals, power-law finding) are confirmed by multiple independent sources. However, the specific output concentration figures (top decile = 30%, top quartile > 50%) could not be independently verified from available sources and may be derived interpretations rather than direct findings reported in the paper.
Probability: Likely (55-80%) | Confidence: Medium
Correction needed: The core study parameters and power-law finding are almost certainly correct. The specific output concentration percentages (30% and 50%) require verification against the original paper text and may represent approximate derivations from the Paretian distribution parameters rather than directly reported findings.
