New preprint!

Ever heard that personality doesn't change? Do you believe that? (you shouldn't)

Using data from an online survey (n = 887) & eight longitudinal datasets (n = 166,971), we compared perceived vs. actual lifespan changes in personality and 20+ individual differences (1/8)

In the last months, I supervised two super-talented research interns (unfortunately Bluesky-less). They were interested in how self-esteem develops after negative events and examined this question in a longitudinal study over 6 months.

You can find their results here:

Ever wondered whether our personality influences our first sexual milestone? 🍒

We explored how the Big Five traits affect the timing of first sexual experiences — and how these, in turn, shape personality traits over time.

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.

One of the best things about doing research is when you aim to do one thing but an unexpected more interesting thing happens. We were concerned that #perpsy intervention research focused too much on changing and not enough on accepting. We compared these approaches and this happened:
Excited to share this preprint on personality interventions that I've been working on the last year together with Travis Miller, @chopwood.bsky.social , and @wiebkeb.bsky.social : osf.io/eb6p7 🥳🥳

In our meta-analyis on changes in personality variability, we integrated data from more than 300 longitudinal studies to answer these questions.
