Description¶
The article names and defines the Statistical–Mechanism Gap Fallacy as "the tendency to collapse the gap between statistical indicators and the psychological, social, or cognitive mechanisms they are presumed to represent". Contextual means, ordinal ranks, and dispersion statistics are treated as "partially overlapping statistical representations of socially experienced comparison environments rather than as isolated psychological mechanisms". The framing motivates modeling mean, rank, and dispersion jointly rather than assuming any single statistic uniquely represents the comparison process.

Claims¶
- The negative contextual-mean effect persists for the top-ranked student in each class, constraining rank-sufficiency accounts [+M]
- Integrative models indicate much of the apparent ordinal-rank effect reflects distributionally scaled relative achievement, while contextual means remain the most robust comparative indicator [+W]
