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]

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.
