A meta-analysis on reducing discrimination finds: 1) passive interventions, such as short-term education or bias reminders, are ineffective 2) targeting behavior directly to inhibit bias (eg making individuals accountable or changing social norms) is helpful psycnet.apa.org/doiLanding?d...

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

***Just Published** We tested whether purpose in life mediates the relation between #loneliness and future risk of death. Loneliness seems to set in motion the erosion of purpose in life, that has downstream consequences on length of life. Paper (open access) doi.org/10.1016/j.so...

New meta finds no correlation between testosterone and risk preference, buuuuut testosterone was mainly measured using 2D:4D (nonsense) or saliva (still bad) and we know from Frey et al. 2017 that the risk measures don't tap into a coherent preference. www.sciencedirect.com/science/arti...

Very happy that our new paper is out in Collabra: Psychology! 😀 Across three studies, we failed to replicate social class-based differences in conformity, which raises further questions about key assumptions of the social cognitive theory of social class.

Improving scientific practice can seem daunting. In this fantastic talk (and thread below), Julia Rohrer shares practical ways to communicate methodological insights to a wider audience of researchers.

Comparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding. RegCheck was built to help make this process easier. Today, we launch RegCheck V2. 🧵 regcheck.app

New post: replicating Loftus and Palmer at scale. rolfzwaan.substack.com/p/memory-mis...

I started reading up on the whole "loneliness pandemic" narrative because this seems like a literature where the age-period-cohort problem may be relevant (or maybe it isn't?). Here's data from Australia (HILDA), average agreement with the statement "I often feel very lonely" (SD of ca. 1.8).>

So thrilled to see this paper in print at PSPR—I propose a new theoretical model of self-protection motivation that reimagines how people might think, feel, and act when navigating self-threats. I enjoy this sort of theoretical work & excited to share it! journals.sagepub.com/doi/10.1177/...

Yikes! “Increased oxygen consumption – for instance in areas involved in calculation – did not coincide with the expected rise in blood flow. …analyses showed that these regions met their additional energy demand by extracting more oxygen from the unchanged blood supply.” www.tum.de/en/news-and-...

Merry Chrismukkah to my readers and friends. I wrote something you might enjoy. open.substack.com/pub/michaeli...

"Behavioural scientists are increasingly calling for context as a key to addressing pressing problems caused by human behaviour. However, despite its powerful ability to generate contextual hypotheses on the basis of relatively simple rules, ecological thinking is rarely applied to human behaviour"

Do not cite an academic paper unless you’ve read it

"Most top achievers (Nobel laureates and world-class musicians, athletes, chess players) demonstrated lower performance than many peers during their early years. Across the highest adult performance, peak performance is negatively correlated with early performance" www.science.org/doi/10.1126/...

Finally, @bjoernhommel.bsky.social's and my paper introducing the SurveyBot3000 is officially out in AMPPS. It's a fine-tuned language model that guesstimates correlations between survey items from text alone. Not perfectly, but useful for search, for example. journals.sagepub.com/doi/10.1177/...

Diederik Stapel was a massive watershed moment in psychology. However, he was -- and let's be slightly glib here -- some guy from The Netherlands who wrote social psychology papers. The full accounting of the Eysenck case is approx, at minimum, TWO STAPELS. retractionwatch.com/2025/12/03/n...

A Review in Nature Reviews Psychology proposes that understanding violent extremism needs integration of trait-descriptive models with process-oriented frameworks that outline mechanisms in social reactivity, needs and mindsets that make some people more at risk for engaging in violent extremism. 🧪

If descriptive research is supposed to be one cure for the replication crisis, why do reviewers and editors keep downgrading descriptive research for not advancing theory? I explore this (in the context of sex and singlehood) in my latest Substack post. unromanticprof.substack.com/p/on-the-val...
