    Part of a larger discussion

    Challenges→Hamilton's coefficient of relationship should be replaced with a more general correlation coefficient.

    A generalized correlation coefficient conflates statistical association with the genealogical causation required to explain why gene frequencies change across generations.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Correlation coefficients measure association strength but say nothing about mechanism, direction, or whether change is due to selection, drift, or migration.
      ?

      Think about whether this reason is strong or weak

    • 2.Genealogical causation requires tracking allele transmission through pedigrees; statistical correlation alone cannot distinguish inherited from environmentally-induced frequency changes.
      ?

      Think about whether this reason is strong or weak

    • 3.Confounding variables (population structure, assortative mating, linkage) can produce correlations mimicking causal evolutionary processes without explaining actual gene flow.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Correlation coefficients in population genetics are often derived from explicit generative models (Hardy-Weinberg, diffusion equations) that already encode genealogical mechanisms.
      ?

      Think about whether this reason is strong or weak

    • 2.The claim assumes correlation and causation are distinct categories, but in well-specified statistical models, correlation structure directly reflects causal architecture of inheritance.
      ?

      Think about whether this reason is strong or weak

    • 3.Empirical validation of correlation-based methods against known pedigrees and simulations shows they reliably track genealogical causation despite not explicitly modeling individual lineages.
      ?

      Think about whether this reason is strong or weak
