Most psychological research tells you if a treatment (or any other cause) works on average. But averages hide a lot. Some people benefit, some see no effect and some may actually be harmed. Our new primer in Psychological Methods tackles this head-on. 🧵

Interested in the science of psychological scale development? Consider joining me for a virtual workshop this coming July! Details at: smart-workshops.com/scale-dev-info And spread the word to scholars and trainees who might be interested!

Any recommendations for a (recent-ish) workflow or tutorial for mixed-effects modelling of experience sampling data in R? Looking for something to hand to my master's student.

This week in Social/Developmental was about generational differences, or as I referred to it: “ @bwroberts.bsky.social and friends keep bludgeoning the zombie horse that won’t die”

Certain I was #866 on the invite list if not for my conference faux pas in 2014

@#$@@# self-reflection. We've been self-reflecting since 2010 in psychology to no avail. Just directly replicate the damn study.

I think I was rejected from 10*/12 places. I was apprehensive about the one I got into, but it changed my life in ways I couldn’t have foreseen (almost all good!) *one wait list

🏆 @simine.com, psychologist at @psychunimelb.bsky.social / @unimelb.bsky.social and Editor-in-Chief of Psychological Science (@psychscience.bsky.social) is a leading voice in the reform movement in psychology - and is now being honored with the €150K Individual Award. Huge congratulations! 🎉

The Big 5 test is about twice as accurate as the Meyers-Briggs Type Indicator for predicting life outcomes, placing the usefulness of the MBTI test halfway between science and astrology. Any psychologist will tell you, the Meyers-Briggs is mostly bullshit. powerofusnewsletter.com/p/why-are-we...

Psychologists, what are your favorite (open) data sets for teaching multilevel modelling? I have a lot of observational examples, would love a therapy RCT with varying effects for therapists or some such.

🔥 New viewpoint paper accepted at Journal of Psychopathology and Clinical Science! I propose a behavioral conceptualization of personality functioning (PF) that reframes the construct in terms of learned self-related repertoires rather than inferred inner structures.

I refer to this invited piece for @psychmag.bsky.social as my #Talking2Strangers manifesto. I wrote about why many of us are reluctant to talk to strangers & what the benefits are (inc. making the world a better place). www.bps.org.uk/psychologist... #OnceUponAStranger @bpsofficial.bsky.social

The term "silence in organizations" describes a pattern of behaviour in which people refrain from speaking up when they have become witnesses, or victims, of misconduct by other members of the organizations that they belong to.

Social psych friends, please help me out with a class discussion by responding to the following (and sharing): What do you see as the biggest challenge for social and personality psychology in the immediate future? What should we as a field be doing better than we are now?

Construct validity is a cornerstone of psychological science. But too often, construct validation practices fall short, leaving uncertainty about what our measures really capture. Why is that? We (@stmllr.bsky.social) tackle this question in our 𝗻𝗲𝘄 𝗽𝗿𝗲𝗽𝗿𝗶𝗻𝘁: 🧵…

In this behemoth effort led by @anhhtran.bsky.social, we reanalysed 11 experience-sampling datasets, and found limited evidence that context (intensity, controllability, and social features) meaningfully shaped everyday emotion regulation strategy use.

@themountaingoats.bsky.social good new single fellas

Outstanding; grateful to hear it

We’ve just published another video on HiTOP that tries to flesh out a bit more how the framework can be helpful in research: youtu.be/q0jOi_Nl1yo We hope it’s useful, and are keen to hear any feedback Thanks again so much to @tashtc.bsky.social for all of her hard work creating this video series ✨

I think about this stuff sometimes. For other open science / “the sky is falling enthusiasts, if you could make a skeptic read earnestly just one article on open science or the credibility crisis, which one would you pick? 1/2

We already know that lagged effects in CLPMs are likely to be upwardly biased, but just how easy is it to find significant effects? Way too easy. I tested CLPMS in 100 randomly selected pairs of correlated variables and found significant effects in 98 of them. New preprint: osf.io/preprints/ps...

Man, I'm sorry, but reading all these AI generated essays from students, it just sucks all the joy out of everything. It's exhausting, makes you into a weird paranoid cop, grinds you down, wastes your time, makes you feel like shit about everything. Fuck this shit technology and all its enablers.

The first draft is DONE.

Life satisfaction mostly declines with age. Previous findings (esp. the famous U-shaped age-SWB trajectory) were artifacts of misspecified models. doi.org/10.1093/esr/...
