- Reposted by Francisco Garre-FrutosVery useful thread outlining a valuable critique of mainstream psychology’s “is there *anything* to be said for another set of rigid guidelines?” approach to its methodological problems.

- Reposted by Francisco Garre-FrutosFirst post of the year, new paper out today: we present possibly the biggest case of systematic Measurement Schmeasurement in tech use. It seems that most studies on gaming (videogame) addiction/disorder haven't measured gaming after all. This research took years, so long 🧵 doi.org/10.1098/rsos...

Together with @haslagter.bsky.social and @fahrenfort.bsky.social I identified falsifiable predictions of active inference and reviewed the extent to which they are supported by empirical results.

- Reposted by Francisco Garre-FrutosOur experiences have countless details, and it can be hard to know which matter. How can we behave effectively in the future when, right now, we don't know what we'll need? Out today in @nathumbehav.nature.com , @marcelomattar.bsky.social and I find that people solve this by using episodic memory.
- Reposted by Francisco Garre-FrutosThe Iowa Gambling Task is an extreme example of Jingle Fallacy and schmeasurement. In 100 articles we found 244 different ways of scoring it, 177 were never reused. Correlations between them range -.99 to .99. At the same time, we show meta-analyses combine these results as if they’re equivalent.
- Reposted by Francisco Garre-FrutosComparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding. RegCheck was built to help make this process easier. Today, we launch RegCheck V2. 🧵 regcheck.app

- Reposted by Francisco Garre-FrutosNew work from @liushuze.bsky.social and @yangxiang.bsky.social osf.io/preprints/ps... People violate Occam's razor when selecting between predictive models. This is surprising given past research (including my own) showing a preference for simplicity.

- Measurement error meets BOLD!
- Reposted by Francisco Garre-FrutosThis paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!
- Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity. www.nature.com/articles/s41...

- Reposted by Francisco Garre-FrutosThis figure from my preprint shows path diagrams for the classic approach, hierarchical/multilevel/mixed models, and Hierarchical Factor Models. The key insight: random slopes per task are equivalent to true scores in experimental effects! When I first realized this, it completely blew my mind.
- Reposted by Francisco Garre-FrutosTwo years ago, I had an idea, one that evolved over time as I kept reading and learning. Today, a major first part of that idea has just become my first PhD preprint, now publicly available on PsyArxiv. Let me tell you a bit more about the story behind it... while I prepare the submission.
