conference paper description
While the homology concept has taken on importance in thinking about the nature of psychological kinds (e.g. Griffiths 1997), no one has shown how comparative psychological and behavioral evidence can distinguish between competing homology claims. I adapt the operational criteria of homology to accomplish this. I consider two competing homology claims that compare human anger with putative aggression systems of nonhuman animals, and demonstrate the effectiveness of these criteria in adjudicating between these claims.
