    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Under perfect correlation, selfish types are always paired with selfish types and altruists with altruists, so P(S partner/S) = P(A partner/A) = 1.
      ?

      Think about whether this reason is strong or weak

    • 2.This assumption implies W(A) = 11 and W(S) = 5.
      ?

      Think about whether this reason is strong or weak

    • 3.When W(A) > W(S), altruism evolves.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Perfect correlation between partners is an idealized limit condition that never obtains in natural populations with any degree of mixing.
      ?

      Think about whether this reason is strong or weak

    • 2.Hamilton's own inclusive fitness framework requires only that relatedness r > cost/benefit ratio, not perfect assortment, for altruism to spread.
      ?

      Think about whether this reason is strong or weak

    • 3.A model that requires perfect correlation to generate altruism explains evolutionary altruism only under conditions that vacate the explanandum's biological interest.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Skyrms and Kitcher argue that correlation-based models conflate the causal mechanism of altruism's spread with a mere bookkeeping redescription of self-interest.
      ?

      Think about whether this reason is strong or weak

    • 2.If altruists only ever interact with altruists under perfect correlation, the fitness gain accrues to a closed group, making 'altruism' indistinguishable from sophisticated within-group self-interest.
      ?

      Think about whether this reason is strong or weak

    • 3.Sober and Wilson's levels-of-selection analysis shows that what appears as altruism under perfect correlation is better described as group selection, not genuine other-directed sacrifice.

    If the correlation between partners is sufficiently strong, in this simple model, then it is possible for the condition W(A) > W(S) to be satisfied, and thus for altruism to evolve. The easiest way to see this is to suppose that the correlation is perfect, i.e., selfish types are always paired with other selfish types, and ditto for altruists, so P(S partner/S) = P(A partner/A) = 1. This assumption implies that W(A)=11 and W(S)=5, so altruism evolves. With intermediate degrees of correlation,
