   Qualified eight overstated causal and deterministic claims: Merton described disproportionate credit to eminent co-authors as a tendency, not an invariable rule; framed rising inequality/citation/market concentration as a tendency in the absence of countervailing forces rather than an inevitability; removed the unsupported 'millions of words annually' precise reading-gap figure; recast the Fortunato et al. 2018 Science review as consistent with cumulative advantage operating alongside merit rather than proving it displaces merit; presented Piketty's r>g thesis as influential-but-debated; changed 'the strongest predictor' of income to 'one of the strongest predictors' and restored a role for individual talent and effort; qualified network-effect winner-take-most outcomes as a tendency, not a guarantee of monopoly; and reframed the hockey relative-age effect as a statistical tendency rather than a deterministic rule.

   Before

   The article stated Merton's rule that eminent researchers receive credit even for equal contributions, that inequality necessarily increases without intervention, a millions-of-words annual reading gap, that Fortunato proves cumulative advantage over merit, that Piketty proves the Matthew Effect is the historical norm, that parents' income is the single strongest predictor and not talent, that network effects produce winner-take-most markets, and that hockey birthdate determines elite advantage.

   After

   Qualified each to what the cited research supports, distinguishing tendencies and correlations from deterministic laws and preserving the real underlying sources (Merton 1968, Stanovich 1986, Fortunato et al. 2018, Piketty 2014, intergenerational-mobility and relative-age literatures).

   Why: The sources are genuine but were characterized more deterministically than the evidence permits. Corrections scope the claims to tendencies and correlations rather than removing the sources.
