So the US administration considers hate speech and disinformation “American viewpoints“? 🙄 HateAid is an organization that also helps climate scientists to defend themselves against online abuse and threats. Its founder was awarded the Order of Merit of the Federal Republic of Germany 🇩🇪 this year.

New publication with @turnbulldugarte.com in @psrm.bsky.social! 🧵 We study whether citizens’ liberal values are selective: do people support policies based on who promotes them? Short answer: Yes, and it's driven by ethnic out-group disidentification. (1/11) 👇 doi.org/10.1017/psrm...

🚨 Now out in Psych Science 🚨 We report an adversarial collaboration (with @donandrewmoore.bsky.social) testing whether overconfidence is genuinely a trait The paper was led by Jabin Binnendyk & Sophia Li (who is fantastic and on the job market!) Free copy here: journals.sagepub.com/eprint/7JIYS...

Partisanship has positive and negative contributions to representative democracies. In POQ, Kasper & Bakker review Bankert's book, which explores how we can amplify the positive impacts while mitigating the negative ones. Read now: doi.org/10.1093/poq/...

🚨 New in Nature+Science!🚨 AI chatbots can shift voter attitudes on candidates & policies, often by 10+pp 🔹Exps in US Canada Poland & UK 🔹More “facts”→more persuasion (not psych tricks) 🔹Increasing persuasiveness reduces "fact" accuracy 🔹Right-leaning bots=more inaccurate

New paper! @william-dinneen.bsky.social @guygrossman.bsky.social Yiqing Xu and I use GPT to code 91k articles from 174 polisci journals (2003–2023)and track research designs, transparency practices, and citations. How has the credibility revolution reshaped the discipline? doi.org/10.31235/osf... 🧵

Excited to share a new preprint with @bnbakker.bsky.social, @ylelkes.bsky.social & @gijsschumacher.bsky.social! doi.org/10.31234/osf... Affective polarization research focuses almost exclusively on valence, despite affect having at least two core dimensions. We show that emotional arousal matters!

Cas Mudde spells out what has become largely the consensus among researchers: moving right on immigration will not weaken the far right nor strengthen social democracy. If your reaction is "but in Denmark" please at least familiarize yourself with Danish politics www.theguardian.com/commentisfre...

Those claiming Dems should retreat on racial justice aren't hard-headed realists, they're pushing against the electoral tide rather than leaning into it. The story of Gen Z isn't about racist backlash or red-pilled young men. It's the most racially progressive generation in American history. 🧵

🔍How does young people's anxiety about the future relate to their political attitudes? Find out in my first PhD paper, just published in the special issue "The Psychology of Pushback" at advances.in/psychology/1...

How do adolescents form their political views, and are they really so different from adults? Next Friday (Nov 7), the IP-PAD Doctoral Network and @hotpoliticslab.bsky.social host a conference in Amsterdam on adolescents and politics (attached program). DM or email [email protected] to join.

🚨Correction to an earlier post on 📘 64.4 🧠 Can we measure #AffectivePolarization without long surveys? A 39-country study 📊 by @jakobkas.bsky.social @gijsschumacher.bsky.social & B.Baker find that brief, smartly chosen measures still work if they span major ideological divides buff.ly/egH1yID

🚀 And this marks our launch of the CampAIgn Tracker 🇳🇱! @meinungsfuehrer.bsky.social and I are glad to finally publish our dashboard where we monitor the use of AI imagery in campaign messages, by parties, politicians & other actors during the election #tk2025 See here www.campaigntracker.nl/en/

These days, everyone is talking about #polarization. But how best to measure it? Olivia Fischer and I have a new paper that empirically compares various operationalizations of polarization (e.g., on people's risk perceptions), including a shiny app to simulate […] [Original post on mstdn.science]

🚨 New publication out @jeppjournal.bsky.social w/ Katrin Praprotnik @luanarusso.bsky.social @markuswagner.bsky.social We show that coalition signals from the mainstream right to the radical right shift, rather than reduce, existing political divisions. Open-access article: doi.org/10.1080/1350...

This comment is the brief spiritual successor to our preprint (linked below) in which we argue much ado within debates over causal effects of social media stems from failing to account for the assumptions required by RCTs. arxiv.org/abs/2505.09254

Exciting new job in Landau 🤩 We’re searching for a Professor of Political Psychology (W2). Very much looking forward to your applications – if you have any questions, please reach out to me. jobs.rptu.de/jobposting/3...

New pre-print! Is there a need for domain-specificity when studying mental health (MH) and politics? In our study in the Netherlands, we find political mental health (PMH) is distinct from MH & has unique political correlates, from polarization to ideological extremism. doi.org/10.31234/osf...

Depolarization is not "a scalable solution for reducing societal-level conflict.... achieving lasting depolarization will likely require....moving beyond individual-level treatments to address the elite behaviors and structural incentives that fuel partisan conflict" www.pnas.org/doi/10.1073/...

How much did Elon's takeover reshape Twitter/X? How did the partisan tilt of social media use change from 2020 to 2024? The ANES 2024 data is out — and this thread answers all your burning questions! 🔥

Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

🎓 This Friday (19.09), we are honored to welcome professor @ulrikeklinger.bsky.social to the #HotPoliticsLab! She will present her work on Facebook user reactions to party campaigning. 📍 Location: Common Room (REC-B9.22) 💻 Or join us online 👉 teams.microsoft.com/dl/launcher/...

🚨New pre-print🚨 "Do citizens’ views of democracy and its actors vary with how they feel?”, @lilymasonphd.bsky.social and I ask in a new paper. Why would they? While citizens widely endorse democracy in principle, temporary factors often shape their views. Also, work on “irrelevant events" 1/8🧵

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia: doi.org/10.5281/zeno... We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical thinking, expertise, academic freedom, & scientific integrity. 1/n

Radical right accommodation really does not work. New paper out with this exceptionally talented team @katharinalawall.bsky.social @robjohns75.bsky.social @drjennings.bsky.social @sarahobolt.bsky.social @zachdickson.bsky.social @danjdevine.bsky.social & @jack-bailey.co.uk doi.org/10.31235/osf...

NEW - Media Platforming and the Normalisation of Extreme Right Views - cup.org/4mmVIAL "exposure to uncritical interviews increases agreement with extreme statements and perceptions of broader support in the population" - @dianebolet.bsky.social & @florianfoos.bsky.social #OpenAccess

🚨Pre-print alert🚨 Research shows citizens in many Western democracies are increasingly affectively polarized––they feel warm toward their own party but quite cold toward opposing parties. But how does it feel to “feel warmly”? @katharinalawall.bsky.social, @mtsakiris.bsky.social & I asked. 🧵1/8

🚨New paper in @cp-trendscognsci.bsky.social 🚨 Why do some ideas spread widely, while others fail to catch on? We review the “psychology of virality,” or the psychological & structural factors that shape information spread online and offline: authors.elsevier.com/c/1lRke4sIRv...

Conspiracies emerge in the wake of high-profile events, but you can’t debunk them with evidence because little yet exists. Does this mean LLMs can’t debunk conspiracies during ongoing events? No! We show they can in a new working paper. PDF: osf.io/preprints/ps...

🚨Preprint alert🚨 How does affective polarization change democracy? Lots of pubs study how AP affects trust, democratic norms, inter-partisan attitudes, and participation. We (w/ @polpsychjoe.bsky.social, @lilymasonphd.bsky.social) examine a vital assumption this research seems to rely on: 1/6🧵

Are we good at describing our feelings about politics? In our new preprint @mrooduijn.bsky.social @isabellareb.bsky.social we show this is not the case: osf.io/preprints/os... [1/6]

Recent research shows that AI can durably reduce belief in conspiracies. But does this work b/c the AI is good at producing evidence, or b/c ppl really trust AI? In a new working paper, we show that the effect persists even if the person thinks they're talking to a human: osf.io/preprints/ps... 🧵

New preprint with @jbakcoleman.bsky.social @lewan.bsky.social @randomwalker.bsky.social @orbenamy.bsky.social @lfoswaldo.bsky.social where we argue for a complex-system perspective to understand the causal effects of social media on society and for a triangulation of methods arxiv.org/abs/2505.09254

🚨 “We just need to recognize that we’re all citizens of this country.” –– Politicians + citizens often stress a shared national identity when trying to bridge racial, partisan, or other group divides. @stysyropoulos.bsky.social & I show why such “shared” identities are doomed to fail. 🧵1/9

1/7 First paper of my dissertation now out in EJPR with @bnbakker.bsky.social & @gijsschumacher.bsky.social Can we measure affective polarization in systems with 6, 10, or even more parties without overburdening respondents or compromising validity? We show how. Paper: doi.org/10.1111/1475...

The first preprint from my PhD is out: osf.io/preprints/ps...! 🥳 We explored the temporal dynamics of four careless responding indicators (response time, within-beep standard deviation, an inconsistency index, occasion-person correlation) in ESM data across different samples. Thread below🧵

Does loneliness correlate with support for the populist radical right? In the Netherlands, yes-lonelier individuals were more likely to support the PRR across 15 years of data (2008-2023), with effect sizes comparable to health correlates of loneliness. (1/9) www.sciencedirect.com/science/arti...

Now published in PNAS! We had a survey in the field at the time of the first assassination attempt on Trump. We found that Rs became significantly less supportive of partisan violence and had increased in-party affect. www.pnas.org/doi/10.1073/...
