    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Traits are jointly determined by multiple causes
      ?

      Think about whether this reason is strong or weak

    • 2.Each causal factor is context-sensitive and contingent
      ?

      Think about whether this reason is strong or weak

    • 3.No single cause operates independently of others in organismal development
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Quantitative genetics legitimately partitions phenotypic variance into heritable and environmental components via heritability coefficients (h²).
      ?

      Think about whether this reason is strong or weak

    • 2.Heritability estimates for traits like height (~0.8) and IQ (~0.5–0.8) within defined populations constitute meaningful, reproducible causal attributions.
      ?

      Think about whether this reason is strong or weak

    • 3.A claim that no proportional attribution is possible conflates population-level statistical decomposition with individual-level developmental causation, invalidating neither.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Galton, Fisher, and the biometrical tradition established that additive genetic variance can dominate phenotypic variance even under gene-environment interaction.
      ?

      Think about whether this reason is strong or weak

    • 2.If certain alleles (e.g., PKU, Huntington's) produce their phenotypic effects across virtually all normal environments, then 'primarily genetic' attribution is empirically warranted for those traits.
      ?

      Think about whether this reason is strong or weak

    But notice the waffle words used by Watson and on the cover of Life: “in large measure” and “mostly in your genes.” Everyone is an interactionist these days, in some sense of “interaction.” Genes and environment, or nature and nurture, are recognized both to be necessary for development: by themselves, genes can’t determine or do anything. Yet, theorists still seem to give the nod to one or the other, suggesting that it is mostly genes or mostly the environment, mostly nature or mostly nurture,
