    Part of a larger discussion

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

    If the correlation coefficient abstracts away from kinship, it loses the connection to inclusive fitness theory that gives Hamilton's Rule its predictive and explanatory bite in real biological populations.

    Key Terms

    Correlation coefficient(as used in statistics and biology)
    A number (ranging from -1 to 1) that measures how strongly two things are related to each other—for example, how closely height and weight tend to move together in a group of people.
    Explanatory bite(as used in philosophy of science)
    The power of a theory to genuinely explain *why* something happens, rather than just describing it without real understanding.
    Hamilton's rule(as used in evolutionary biology and ethics)
    A mathematical formula (rb > c) used by biologists and philosophers to predict when an animal will help relatives even at a cost to itself; it says that helping is worthwhile if the benefit to relatives (weighted by how closely related they are) outweighs the cost to the helper.
    Inclusive fitness theory(theoretical framework predicting why these moral intuitions exist)
    An evolutionary biology idea that organisms don't just try to survive and reproduce themselves—they also help their relatives survive because relatives share their genes.

    Kinship(as what genetic homogeneity reduces to)
    Family relationships; how closely related people are to each other through blood.
    Predictive bite(as used in philosophy of science)
    The ability of a theory to actually make accurate predictions about what will happen in the real world—the stronger the 'bite,' the better it explains reality.
