1. Changing Minds: When Do People Resist Scientific Findings?
When scientific findings touch on people's identities or values, people don't simply weigh the evidence. They also try to protect their beliefs, self-image, and more.

Preregistrations without Code do not Prevent P-Hacking: You can increase your chances for a significant finding in the absence of real effects even with correlations and t test despite having preregistered your hypothesis (e.g., simply changing arguments in the functions).

I made an error that I found thanks to @lukaswallrich.bsky.social. The code and preprint have been corrected/updated. Effects on false positive rates are smaller and only for alternative and correlation method but I think the overall argument still works.

Metacheck can now automatically 1) download a preprint from PsyArXiv, 2) create a report of the checks (stats, reporting guidelines, references, code, etc), 3) retrieve the authors email, and 4) send them the report.
Would you as an author appreciate this? When yes, when no?

haha, well, at least 4% of people say shape-shifting lizards control the govt.
Also, some great work by Seetahul and Greitemeyer suggests that participants are more likely to react when they think studies will counteract their interests (journals.sagepub.com/doi/full/10....)

If you’ve ever attempted a meta-analysis, you’ll know that authors generally do a poor job reporting statistics. If you do this well, you’ll improve your chances of your work being included in a future meta-analysis.

Check out this really cool multilab project about the difference in short-term memory between musicians and non-musicians! By @masssimo006.bsky.social, @francescatalamini.bsky.social, and researchers from 33 institutions around the world.
Finally, our 4-year long project has been published! We have conducted a multi-lab study comparing STM of musicians and nonmusicians, collecting many other cognitive, personality, musical, and demographic variables!

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!
