Grumpy IO psychologist with an interest in research methods, meta-science and personality. Views are my own and not those of my employer.

Supply chains are completely insane. Here I am, in a small town in central Iowa in November, and I can buy a perfectly ripe Pomegranate for $1 at a store that is a block away from my house.

One of the giants of social psychology was a serial sexual harasser.

This new report reveals how Miles Hewstone touched, bullied, and sexual harassed numerous women during his 18 years at the University of Oxford. It's amazing how often bullying and sexual harassment go together in academia.

At some point Harvard will surely figure out if they just keep hiring awful people or if they also turn previously non-awful people into awful people.

Using PISA data, analysis shows that:

✳️ traditional teaching methods (lecturing, memorization & repetition of tasks) ==> better math learning.

✳️ "Innovative" teaching ==> worse math learning.

Effects amplified among low SES kids.

I know that at this point it's a subplot in the Epstein files drama, but I feel compelled to point out, once again, that Larry Summers HAS NO BUSINESS teaching students at ANY university ever again!

Why Is Larry Summers Still Employed?
The revelations about the economist’s attempts to pressure a women into a “relationship”—with guidance from Jeffrey Epstein—should finally disqualify him from teaching students.

I am hoping to recruit a graduate student for next year. That person would help conduct research on leadership, individual differences, and methodological skullduggery. Please forward to any potentially interested students.

It's been more than 7 months since I alerted an APA editor to serious statistical impossibilities and discrepancies in papers published in their journal by the same set of authors. How can it take 7 months to "investigate" something that can be confirmed on the back of napkin in 5 minutes?

I appreciate the intention but I really wish that faculty paid much less attention to these personal statements. You have no idea who wrote them (esp. in the age of LLMs) and applicants for whom English is not their primary language may be stellar but not be able to ace these types of nuances.
It’s grad school application season, and I wanted to give some public advice.

This. Most "high impact factor" journals publish some absolute BS nonsense and "low impact factor" journals publish stellar stuff. If you want to base your evaluations of an article on citations (please don't) then base it on the citations that the article garners - not on those of other paper.
That merely being “under review” by a Nature family journal is offered as a quality proxy for a paper is a tragic illustration of the extent to which academia is addicted to brands and outsources evaluation

Go home APA - you are drunk. Just got an e-mail from an APA journal reminding me that my review was due on 25th October and that it is now -5 days late.

I've learnt far too late that the secret to being a "successful" academic is making one finding or phenomenon your entire identity and then just cudgeling that thing to death for the next 40 years. Ideally you should be able to report at least 100 p-hacked 2x2 ANOVAs.

We have armed secret police kidnapping people off the street based on the color of their skin.

When we win: we will haul them before a Senate committee. The masks will come off. There will be consequences.

Why is this not getting more attention in my academic feeds. A professor got doxed and death-threats, tried to leave the US, and is not being allowed to. Connect the dots.

Only very serious management scholars get to conduct an experiment that shows no difference between the treatment and control group and then report that the treatment had an effect because of "mediation" ™.
