Why do some people feel lonelier than others? Drawing on 441 effects, our meta-analysis shows a clear link between insecure attachment orientations (anxious or avoidant) and loneliness (r= .38).

Auf Englisch sagt man, "I have a book inside me." Das hatte ich bis vor kurzem auch, aber jetzt nicht mehr - denn ich habe es tatsächlich (fast) geschrieben, und am 24.3.2026 wird es so erscheinen:

#Einsamkeit

A year ago, 20 German personality psychologists came together under the leadership of John Rauthmann to assess the status of the field (not only from a German perspective). An English-language version of this paper (in press at Psychologische Rundschau) is now available:

New paper in PsychScience: Partial election results fuel fraud beliefs via cumulative redundancy bias. Early leaders are favored; late flips spark suspicion. 7 studies, including 2020 GA data, show this persists despite explanations. @moritzingendahl.bsky.social journals.sagepub.com/doi/10.1177/...

New preprint: osf.io/8c6sz_v1
@mdkraemer.bsky.social and I, with our fantastic co-authors Cornelia Wrzus, Yannick Roos and @drichter77.bsky.social examined how social contact, desire, and affect dynamically interact across different modalities (in-person, digital) and time scales (hourly, daily).

Preprint ALERT!

We used data from the GLUECK study to explore network dynamics in the subjective well-being of adolescents. Our findings highlight the central role of school satisfaction and strong links between domain satisfaction and affective well-being.

Be sure to check out Debbi's first first author paper on who stays lonely and who doesn't following social loss events!

#Loneliness is still widespread among young people in Europe. In a new study for @bertelsmannst.bsky.social, we found that in 2024, 57% of youth in Europe are at least moderately lonely.

The question I've got asked most frequently at conferences when I was presenting something on the perception of life events was whether there are any age differences.

Using data from the SOEP-IS, we addressed this simple but interessting question.

I'm very humbled and extremely happy to announce that my research will be supported by an #ERC Consolidator Grant in the next 5 years. More soon!

Can people intentionally change their personality?

Happy to share that our review on volitional personality change research has now been published at Nature Communications.

We examined in 2 studies how contextual social factors (e.g., neighborhood, household composition) relate to differential regulation of social interactions in daily
