Dat speelt ook zeker een rol.

Nog 2 punten:
- In het experimentele onderzoek dat ik eerder noem is de voorkeur voor positieve emotie over negatieve emotie minder sterk bij rechts dan bij links.
- er zit wel degelijk positieve emotionele aspecten in communicatie Wilders (denk humor, Milders, "De agenda voor hoop en optimisme")

Specifiek over reden om radicaal-rechts populistisch te stemmen heb ik het volgende geschreven:

- De +/- 10 zetels die D66 afgelopen weken steeg in peilingen is een campagne-effect waar de positieve emotionele campagne van D66 een positieve bijdrage aan levert (mijn interpretatie)
- Maar er zijn ook andere reden om te stemmen. [1/3]

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]
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]

Goed stuk Merijn. Het is een merkwaardige kronkel waar links zich in draait: anti-populist, dus pro-systeem, pro-elite. Gek als oppositie, vanuit historisch perspectief en campagne overwegingen.

- 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 (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.

- 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!

- had an inspiring workshop with professionals and scientists working on polarization Perspectieven in Polarisatie community

- Did two big interviews for newspapers about the elections

- Posted two new preprints (with @bnbakker.bsky.social @delaneypeterson.bsky.social & Maaike Homan)

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.

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.

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.

Day 3 of the #ISPPAcademy! We had highly engaging discussions starting with @gijsschumacher.bsky.social's session on the emotions and democratic politics and the cutting-edge research done in the #HotPoliticsLab.

We then continued with ‪@iriszez.bsky.social discussing conspiracy theories.
