R0007/2026-03-19/C001 — Claim Definition¶
Claim as Received¶
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%.
Claim as Clarified¶
This is a compound claim with two parts:
-
Study parameters: O'Boyle and Aguinis (2012) conducted five studies encompassing 198 samples and 633,263 individuals across researchers, entertainers, politicians, and athletes, finding that individual performance follows a Paretian (power-law) distribution rather than a normal (Gaussian) distribution.
-
Output concentration: Under this distribution, the top decile (top 10%) produces approximately 30% of total output, and the top quartile (top 25%) produces more than 50% of total output.
Implicit assumption: The output concentration figures are reported findings from the paper rather than derived calculations.
BLUF¶
The study parameters and power-law finding are confirmed with high confidence. The specific output concentration percentages could not be independently verified and may represent approximate derivations rather than directly reported findings.
Scope¶
- Domain: Organizational behavior / industrial-organizational psychology
- Timeframe: 2012 publication; studies span multiple time periods
- Testability: Study parameters verifiable via published paper; output concentration figures require access to full paper text
Assessment Summary¶
Probability: Likely (55-80%)
Confidence: Medium
Hypothesis outcome: H2 (partially correct) is best supported. The core study parameters are verified, but the specific output concentration percentages cannot be confirmed from available secondary sources.
