“…If we look at the specific individual-level variables that have served as outcomes in the AJS, they permit a rough, heuristic division that will prove useful for thinking about genes as causes and as parts of explanations. First are actions, whether interesting in single occurrences (e.g., vote choice [Manza and Brooks 1998], first intercourse [Bearman and Bruckner 2001]) or as a recurrent pattern over time (e.g., parental investment in children [Freese and Powell 1999], political participation [Antunes and Gaitz 1975]). Second are actors' internal states, which are often regarded as interesting for what they are taken to imply for action (thinking about divorce [Huber and Spitze 1980]) or about the causality of sociocultural forces (social attitudes [DiMaggio, Evans, and Bryson 1996], perceptions of crime rates [Quillian and Pager 2001]), but sometimes are taken as an end in themselves (alienation [Kohn 1976], job satisfaction [Gruenberg 1980]).…”
