ABSTRACT
In this chapter we return to the basic purposes of a comparative psychology of human populations, formulate some of the fundamental questions of culture and personality in terms of the evolutionary framework advanced in the foregoing chapters, and ask: What must we know to answer those questions, and what would we do with the answers if we had them? A theoretical formulation is only valuable if it guides empirical research in significant directions; here I attempt to foresee the directions and assess the significance of the research implied by population psychology as an evolutionary theory of culture and personality.
