Not all unpolarized citizens are alike—some feel lukewarm toward parties while others feel cold, with different effects on democratic participation. 🗳️❄️😐

🧐 What do citizens think about "null results" in scientific research? To find out, @johnholbein1.bsky.social & I fielded a large-scale online experiment. We gave respondents straightforward info about a study, asked them some Qs, showed them the results, then asked them Qs again.

So, does affective polarization change citizens’ winningness to support democratic norms or participate? It depends on what “low AP” we’re comparing “high AP” to. 🧵10/10 Thanks to everyone who helped us develop this paper along the way! : )

unpolarized groups and, crucially, that the two differ on our various outcomes. Spoiler alert: we find that no group is consistently “better” for democracy (ie more trusting, democratic, participating). It seems that different groups contribute different elements to our democratic dinner. 🧵9/10

We conduct cluster analyses on 3 US datasets to find the relevant patterns of unpolarized citizens and map those clusters on a bunch of outcomes (trust, norm support, partisan behavior, participation). We find TWO relevant 🧵8/10

this person has an AP score of 10, denoting low affective polarization. But shouldn’t it matter whether we’re comparing affectively polarized individuals to a baseline that loves both parties, feels lukewarm toward both parties, hates both parties, or a heterogeneous mix of all of the 🧵6/10

Peter Luca Versteegen @versteegenluca.bsky.social · 31/08/2026
This operationalization nicely differentiates between high and low affective polarization. But it treats everyone with low affective polarization scores alike. To illustrate this for a 2-party case: no matter if someone likes both parties with 80 and 70, 50 and 40, or 30 and 20, 🧵5/10

Peter Luca Versteegen @versteegenluca.bsky.social · 31/08/2026
We argue that this blind spot is a consequence of how we measure AP: The standard operationalization calculates affective polarization as the difference (or, in multi-party systems, variance) in people’s warmth toward the available parties. 🧵4/10

group and take them as the reference we compare affectively polarized people to. But the share of citizens who is NOT affectively polarized is huge and treating all of them alike risks masking heterogeneity. 🧵3/10

In a new paper, @polpsychjoe.bsky.social , @lilymasonphd.bsky.social, and I argue that such questions assume homogenous levels of norm support and participation among affectively UNpolarized citizens. That is, we tend to treat all affectively unpolarized citizens as one 🧵2/10

“Writing is hard.” Thrilled to share that this simple idea led to a new paper in Political Analysis! Where most text methods focus on content, I test if expression is also effortful action. I find simple measures like character counts reveal attitudes and predict voting. cup.org/4cUmoXi 1/
Text as Behavior
Text as Behavior published in Political Analysis

by Omar Wasow

Abstract

Text analysis typically focuses on content—such as sentiment or topic—but expression is also a form of effortful action. Building on this insight, I propose using simple features of open-ended tasks to study text as behavior. This approach treats expression, such as writing, as cognitively, emotionally and temporally “costly” for subjects but inexpensive for researchers. I show basic statistics like the number of characters can approximate effort and significantly improve estimation of quantities of interest, including candidate choice, the probability of turning out to vote and psychological states about which a subject may not be fully aware. Further, these methods can convert nonresponse into informative data; validate survey instruments; serve as mechanism checks; be hard for a subject to “game”; work across different languages and analogize well to real-world situations. In sum, text as behavior can help address a range of issues related to quantifying attitudes and actions.
