    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The nature-nurture controversy is undermined by the context-dependence of genes as causes
      ?

      Think about whether this reason is strong or weak

    • 2.Context-dependence arises from the non-additivity of gene-gene and gene-environment interactions
      ?

      Think about whether this reason is strong or weak

    • 3.This same problem affects heritability measures and is not eliminated by molecular genetic methods
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Molecular techniques identify specific causal mechanisms (e.g., gene expression pathways) that heritability statistics cannot, enabling interventions that dissolve rather than merely quantify nature-nurture questions.
      ?

      Think about whether this reason is strong or weak

    • 2.Resolving the controversy requires causal specificity about *which* factors explain variation, not just acknowledgment that interactions exist—a standard molecular genetics can meet where quantitative genetics cannot.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Kitcher and Griffiths argue that gene-environment interaction loses explanatory force when molecular biology identifies developmental reaction norms with sufficient precision to predict phenotypic outcomes across environments.
      ?

      Think about whether this reason is strong or weak

    • 2.If non-additivity is the core obstacle, then mapping complete genotype-environment interaction surfaces via molecular methods transforms an unresolvable controversy into a tractable empirical research program.
      ?

      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,
