Top download from APA Journals in 2025 examines occupational differences in #personality traits, drawing on Big Five domains and personality nuances. Full article + interactive tool to explore the results ➡️ https://bit.ly/3NMyk3h @katlinanni.bsky.social @ukuvainik.bsky.social @renemottus.bsky.social
New episode alert! 🚨 @renemottus.bsky.social spoke with Elliot Berkman, @kaitlynmwerner.bsky.social and @andero.bsky.social about self-regulation and affect regulation, and how each of the guests' research connects to personality psychology. Check it out!

Personality change people: does it make sense to think that to change a broader trait domain (neuroticism, agreeableness, conscientiousness) one could consider starting with those facets/nuances that are furthest from the desired levels?

Rethinking measurement invariance causally Highlights: It is preferable to work with a causal definition of measurement invariance A violation of measurement invariance is a potentially substantively interesting observation Standard tests for measurement invariance rely on strong assumptions Group differences can be thought of as descriptive results
Conceptual graph illustration the central points of the manuscript. A group variable is potentiall connected to a construct of interest which affects items. Measurement invariance is violated if the group variable directly affects the items, for example by modifying the loadings from the construct to the items, or by directly affecting an item
To make this less abstract, consider a scenario where students take an exam, R, meant to capture some ability, T, and then are admitted to a program, V, depending on their exam results: R → V. This is sufficient to result in a violation of the statistical definition of measurement invariance. Exam results and admission are not independent given ability because exam results have a direct effect on admission. Even if we know somebody’s ability (e.g., we know it’s very high), learning about their admission status (e.g., they were not admitted) can tell us something about their exam result (e.g., it may have been worse than expected). According to the causal definition, this in itself does not constitute measurement bias, which seems a sensible conclusion here. After all, the scenario does not involve any reason to believe that the measurement process varied systematically by admission status. Admission happens after the exams took place, it cannot retroactively influence the measurement process (and, for example, lead to unfair treatment depending on admission status).
New paper out with @boryslaw.bsky.social 🥳 In which we sketch out how to rethink measurement invariance causally for applied researchers. And provide a causal definition of measurement invariance!

I once proposed a simple tool to understand and visualise correlations, TACT.
doi.org/10.5964/ps.7...
This app makes it even easier to use: apps.psych.ut.ee/TACT/
Since otherwise the stability is confounded with test-specific variance (e.g., facets/nuances, stable item interpretations etc).
It's like people define latent traits as the shared variance of multiple indicators cross-sectionally -- here we extend to longitudinal data.
I suppose yes, this makes them real in some sense.
My follow-up question is: if these "real" Big Five exist independently of their tests, then to study the "real" rank-order stability of the Big Five, we should assess them with different tests at different time-points.
Personality folks, is there an argument to be made for latent Big Five traits that exist independently of the particular test we happen to use to assess them?
(If yes, I will have a follow-up question)
Now published in Current Opinion, we show why personality research should embrace multi-rater studies and how this can be achieved in practice, even at scale. Often, this is the most realistic way to avoid (reliably) invalid conclusions.

What I really enjoy about Bluesky is how you can serendipitously learn so much stuff. You’ve probably heard of Dunbar’s number — the idea that humans can only maintain X stable social relationships, because *gestures vaguely* brain? Here’s a deconstruction of it.>
Good thing there is a reference for why this (or any such) number makes no sense.
Folks, it's time to submit your papers to PCI Psychology. Here is our invitation to you, taken from our editorial osf.io/preprints/ps...
What is the best public domain occupational interest test currently available (still relevant for the current job market)?
And how that difference plays out in other demographic trends (see number of kids 👀). Personality is up next 😁
