Tóm tắt	This measure assesses citizens' willingness to endorse violence against political opponents, a key indicator of democratic fragility. Nathan Kalmoe and Lilliana Mason's research, synthesized in Radical American Partisanship (2022), maps a continuum of violent partisan hostility from wishing harm on the other side to endorsing lethal attacks, using representative surveys and embedded behavioral experiments. Because such attitudes are rare and the items are extreme, the measure has prompted vigorous methodological debate, exemplified by Westwood and colleagues' demonstration that inattentive responding and item design can substantially inflate apparent support, making bias correction central to credible estimates.	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.
