概要	Implicit political attitude measures assess automatic, relatively uncontrolled evaluations of political objects, candidates, parties, racial and social groups, using reaction-time and misattribution tasks rather than self-report. The two leading instruments are the Implicit Association Test (Greenwald et al., 1998), which infers attitudes from the speed of categorization, and the Affect Misattribution Procedure (Payne et al., 2005), which infers them from how a prime biases judgments of ambiguous targets.	Affective polarization measurement quantifies the gap between how positively people feel toward their own political party (the in-party) and how negatively they feel toward the opposing party (the out-party). Iyengar, Sood and Lelkes (2012) showed that this affective divide has grown sharply even where issue positions have not, reframing polarization as a social-identity phenomenon of partisan like and dislike rather than ideological distance.
