HSRP-516

Americans increasingly dislike and distrust the other party, and that dislike has become a main driver of loyalty to their own; it is measured across Europe's multi-party systems too.

2. The claim, in full

Americans increasingly dislike and distrust the other party, and that dislike has become a main driver of loyalty to their own; it is measured across Europe's multi-party systems too.

Cited on: /the-hive-mind, THE PARTY HIVE MIND › Dislike of the other side. Entered 2026-10-12 with the /the-hive-mind rewrite; tag NEW-W2d-3.

3. What it rests on

An identity has a mirror image: dislike of the other side. "Ordinary Americans increasingly dislike and distrust those from the other party," a review by Shanto Iyengar and colleagues reports [SRC-941]. They call this "affective polarization", and track it on several measures, from ratings of the other side to comfort with a child marrying across party lines, among Democrats and Republicans alike. Alan Abramowitz and Steven Webster found that dislike of the other party had become a main driver of loyalty to one's own, a pattern they call "negative partisanship" [SRC-942]. Dislike of rival parties is measured across Europe's multi-party systems too, at levels that vary by country [SRC-943].

Dislike of the other side is marker M4 at work: the other side discredited in advance. US AND THEM sets out when such dislike turns to hostility. Whether it harms democratic conduct is disputed HSRP-414.

8. Related observations

HSRP-414 · PROBABLE · THE TWO HIVE MINDS: party loyalty in the United States works as a social identity, and voters largely follow it. Rests on: the publisher's description of Achen and Bartels, Democracy for Realists (2016) (voters choose "on the basis of social identities and partisan loyalties, not political issues"; the book itself not opened); Finkel and fourteen co-authors, Science 370 (2020) (political sectarianism defined at p. 533; "cold feelings toward the out-party now exceed warm feelings toward the in-party", p. 533; a majority-party candidate "could get elected despite openly violating democratic principles", p. 535, reporting Graham and Svolik 2020, not opened); Rathje, Van Bavel and van der Linden, PNAS 2021 (each out-group term raised the odds of a post being shared by 67%, from the abstract, which gives n = 2,730,215; observational; sharing, not votes). Washington's Farewell Address (1796) is quoted as a text, the two fragments being the opening and closing words of one sentence. Against, carried on the page: Druckman, Green and Iyengar (2023) found "scant evidence of a direct link between affective polarization and democratic backsliding in the U.S." That the two party hive minds are steered by design is not yet found, and it is not yet known whether it will be found; what is found is an incentive that rewards hostility. The model of the hive mind is this site's own, set out on /the-hive-mind, whose section 9 is "THE TWO-PARTY ARCHITECTURE", and on /psycho-vulgarism.
