I'm always keen to read research where an intervention's success depends on individual differences.

Here, science-relevant info on videogame (VG) use & aggression:

✳️ WORKS among low VG users
✳️ FAILS among high users (i.e, no change)
✳️ BACKFIRES among very high users!

Anyone familiar with robust regression for heavy-tailed residuals? Seems there are many alternatives. The only method I've learned is Bayesian regression with regularizing priors (from @rmcelreath.bsky.social book) and for the moment I want a frequentist alternative (sorry Bayesians) #stats #rstats

New study on #BlueSky for #SciComm.

“Bluesky posts demonstrate substantially higher levels of interaction (likes, reposts, replies, and quotes) and greater textual originality than previously reported for X, suggesting both stronger interactive and more interpretive engagement.”

Research posts on Bluesky are more original — and get better engagement
Bluesky posts about science garner more likes and reposts than similar ones on X.

It’s fascinating to argue that LLMs mimic humans when they’re producing effects that aren’t replicated in humans.

Reposted by Yashvin Seetahul
So, as evidence of "mimicry", we have the LLM exhibiting effect sizes in the 90th-98th percentile of effects seen in studies of human beings in a paradigm where humans do not replicably show the effect. Not very compelling IMO.
