- Reposted by Gijs SchumacherExcited 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!
- Dat de positieve campagne van D66 gewerkt heeft is eigenlijk niet verrassend. Kiezers van links tot rechts hebben de voorkeur dat hun partijleider positieve emoties gebruikt en minder negatieve emoties. De data hieronder uit drie surveys laten dit zien (grootste partijen op dat moment). [1/2]
- Ook experimenteel onderzoek dat ik naar emoties heb verricht laat zien dat positieve emoties uitstekend werken. Een goede campagne is natuurlijk wel meer dan een paar positieve woorden te gebruiken. Het nonverbale is net zo belangrijk. [2/2]
- Wrapping up the week (week 2) - got two R&Rs with minor revisions this week. Both about political interest, emotions and identities. So stay tuned for some existing stuff coming up. - Had a great day with the Challenges to Democracy group. Exciting presentation by Trevor Incerti and a nice diner.
- - Had some real empty space in my agenda to work on a review about the role of emotions in politics! - Went to a great talk at the #Hotpoliticslab by Alexandros Giannelis, Ph.D. on genes & politics. Now time for a beer!
- Wrapping up the week - Posted two new (tt) Assistant Professorship position in my department: werkenbij.uva.nl/en/vacancies... ... I am chairing this committee, so let me know if you have questions
- - Posted two new preprints (with @bnbakker.bsky.social @delaneypeterson.bsky.social & Maaike Homan) On politics and mental health: osf.io/preprints/ps... On politicians’ emotional appeals and voting: osf.io/preprints/ps...
- - had an inspiring workshop with professionals and scientists working on polarization Perspectieven in Polarisatie community - Did two big interviews for newspapers about the elections
- - Hosted Tago Atsushi in our weekly #Hotpoliticslab seminar with a super interesting talk about physiological responses to war imagery. - Failed again to get ICT services to let me add students to my Teams folder. Time for a drink!
- Reposted by Gijs SchumacherNew 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...

- Reposted by Gijs Schumacher3/4 Why might this be? a) Partisan identity may be less chronically active in the NL, b) Familiarity and affect toward specific leaders varies across participants, c) Lack of basic visual cues related to group membership, d) Partisanship may be constructed later, or require more political context.
- Reposted by Gijs Schumacher2/4 Politicians’ faces did evoke stronger N170 responses than strangers’ faces, possibly due to affective salience. Yet, we did not observe partisan differences in the P200 or N200 components. This stands in contrast to robust effects reported in studies on racial and minimal group bias.

- 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]
- We asked people to (1) describe an emotional event they experienced and (2) to evaluate this events answering questions about for example the certainty, moral dimension, and controllability of the situation. These so-called appraisals should theoretically link with specific discrete emotions [2/6]
- Using this task earlier work shows that these appraisals predict the correct emotional labels people had provided (~70%). This work asked people about general emotional events. We asked half of our sample to describe their emotions about politics, and the other half received the original task. [3/6]

- 🧵 Why do facts often change beliefs but not attitudes? In a new WP with @yamilrvelez.bsky.social and @scottclifford.bsky.social, we caution against interpreting this as rigidity or motivated reasoning. Often, the beliefs *relevant* to people’s attitudes are not what researchers expect.

- Kan empathy polarisatie verminderen? In een nieuwe (replicatie) studie laat ik met Matthijs Gillissen en @mrooduijn.bsky.social zien dat de verschillende componenten van empathie verschillende effecten hebben www.cambridge.org/core/journal... [1/4]
- We vinden dat "empathische bezorgdheid" positief samenhangt met positieve gevoelens over jouw partij (inparty), terwijl "perspectief-nemen" positief samenhangt met positievere gevoelens over de "outparty'. Beide concepten zijn onderdeel van het bredere begrip empathie. [2/4]
- Deze studie is gedaan in Nederland en is een replicatie van een Amerikaanse studie uitgevoerd door Elizabeth Simas, @scottclifford.bsky.social en @justinkirkland.bsky.social. Onze resultaten over 'perspectief-nemen' zijn iets sterker dan die van hen. [3/4]
- Het is bijzonder om vergelijkbare resultaten te vinden in 2 landen die zo sterk verschillen qua politiek. De resultaten laten zien dat interventies zich specifiek op 1 component van empathie moeten richten om polarisatie te verminderen. [4/4]
- Can we reduce polarization with empathy? Just published a new (replication) study with @mrooduijn.bsky.social and Matthijs Gillissen showing that different components of empathy have quite different effects [1/5] www.cambridge.org/core/journal...
- We find that empathic concern correlates positively with inparty favoritism, while perspective-taking is positively correlated with liking the outparty more. Both concepts are part of the broader concept of empathy. Experimental results further support this idea. [2/5]
- This study is set in the Netherlands and is a replication of an earlier US-based study by Elizabeth Simas, @scottclifford.bsky.social and @justinkirkland.bsky.social. Their results are highly identical to ours, with our perspective-taking results being somewhat stronger. [3/5]
