Abstract: This piece critiques the dominant assumption in social and political psychology, as well as in political science and other disciplines, that polarization is inherently undesirable and should therefore be reduced under all circumstances. We argue that this premise reflects a neutrality bias (or depoliticizing bias) that obscures the asymmetrical nature of contemporary political conflict. We distinguish democratic polarizationβ€”agonistic contestation among actors who accept multicultural pluralism, democratic institutions and election outcomes, civil and human rights, and epistemic accountabilityβ€”from anti-democratic polarization, in which conflict is strategically mobilized to delegitimize opponents, erode institutional constraints, and normalize dehumanization, scapegoating, misinformation, anti-scientific, and conspiratorial narratives as a route to political power.

Instead, identities such as nationality, age, or gender tend to be more central. Engaging with those identities and countering attempts to use them in exclusionary ways or to stir further conflict may offer a way toward reducing societal division.

The social groups we belong to shape how we see ourselves, but which ones matter most? Using survey data from ~2,000 UK adults, I show that while political parties and ideology may matter in certain contexts, they are rarely the first things that come to mind when people think about who they are.

We compare ANOVA/SDT/GLMM for binary judgments in 20 datasets of the truth effect. #lme4

Main conclusion:
"GLMMs are a theoretically sound and practically robust method and thus superior for analyzing binary judgments in social and cognitive psychology.”

Average agreement with the statement "I often feel very lonely" plotted over time

I started reading up on the whole "loneliness pandemic" narrative because this seems like a literature where the age-period-cohort problem may be relevant (or maybe it isn't?).

Here's data from Australia (HILDA), average agreement with the statement "I often feel very lonely" (SD of ca. 1.8).>

To summarize: By integrating arousal, we strengthen the conceptual foundations of affective polarization research and improve the predictive validity of related measures. We show the value of taking the 'affect' in affective polarization seriously.

Finally, we compare our framework to discrete-emotions approaches demonstrating that our model based on valence and arousal captures most of the same information while being more parsimonious.

We also introduce a one-dimensional arousal-weighted metric of affective polarization as a compromise solution that remains similar to previous operationalizations, but more effectively integrates emotional arousal.

3 - An arousal-based dimension of affective polarization shows distinct (and often stronger) associations with key political correlates such as political engagement, ideological extremity, and democratic attitudes.

2 - Valence and arousal are distinct dimensions both needed to describe affective experiences in reaction to political actors. Arousal does not simply mirror valence or its intensity. Strong negative evaluations may be accompanied by either high or low arousal, depending on the context.

1 - Traditional feeling thermometers are a measure of emotional valence.
