Psychology professor into kid personality and its various manifestations. Also entrepreneurship, leadership, construct validity, and nachos.

(Skipping #ASA2026 because I dropped my membership. Anybody who is interested in methodology who is there, can you help gauge and seed interest in a reviewer boycott until ASA Council allows its journals to have open science policies for quant soc? Thanks.)

New meta by @peterhaehner.bsky.social et al (I'm a little middle author) on individual differences in personality change across the lifespan (229 studies, N = 230k) 10.1037/bul0000525 Cool finding (imo): For all Big Five, variance in change is greatest in youth, declining through young adulthood!

Individual differences in change for each of the Big Five across ages 0 to 80. The trend for each trait is that individual differences in change are decreasing with age.

New post! "Making Sense of Replications (and Some Nonsense about the Replication Crisis)," in which I suggest a journal club reading list of new papers on replication, and push back on claims that the replication crisis is fake. getsyeducated.substack.com/p/making-sen...

Making Sense of Replications (and Some Nonsense about the Replication Crisis)

It’s hard to overstate just how much the culture around replication in science has changed over the past 15 years.

Experience as a journal editor does not preclude impatiently waiting for a recently submitted manuscript to get assigned or desk rejected. Because THAT editor should be managing their queue 24/7, amirite?

A study in @nature.com shows that while complex traits are polygenic in population at large, they have distinct architecture at tails, where rare variants of large effect act as key drivers. Not a surprising finding but neat to see it demonstrated in large UK Biobank cohort across traits & methods.🧪

Distinct genetic architecture in the tails of complex traits - Nature

Genome-wide analyses in multiancestry and European cohorts show that in complex traits, rare alleles have disproportionately large effects at the tails of the phenotypic spectrum compared with common ...

absolutely wild to see people out here saying that it is responsibility of peer reviewers to check for hallucinated references. it is hard enough to persuade people to read articles and provide reviews. expecting them to spend hours cross reffing literature is unreal.

2. We push back against the idea that reform must wait for broad stakeholder buy-in and cultural alignment. We use smoking as an analogy. Smoking rates did not decline primarily because smokers were persuaded. They declined because smoking became more costly, inconvenient, and denormalized. 6/8

We also argue that treating Open Science as merely one more “content area” to squeeze into graduate curricula is a category mistake. Transparency is to science what food safety is to culinary training: foundational hygiene, not an elective specialization. 5/8
