Evolutionary psychology, ecological rationality, and the unification of the behavioral sciences

For two decades, the integrated causal model of evolutionary psychology (EP) has constituted an interdisciplinary nucleus around which a single unified theoretical and empirical behavioral science has been crystallizing - while progressively resolving problems (such as defective logical and statistical reasoning) that bedevil Gintis's beliefs, preferences, and constraints (BPC) framework. Although both frameworks are similar, EP is empirically better supported, theoretically richer, and offers deeper unification.
