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 and power-law finding are fully confirmed. The output concentration percentages are reasonable approximations of Paretian distribution properties but are not precise figures uniformly reported in the paper. The claim is substantially correct with minor imprecision on the quantitative characterizations.

Probability: Very likely (80-95%) | Confidence: High

Correction needed: The output concentration percentages (top decile ~30%, top quartile >50%) are consistent with Paretian distributions but should be characterized as implications of the distribution rather than exact reported figures.
