New preprint by @semihaktepe.bsky.social 🎉
We compare ANOVA/SDT/GLMM for binary judgments in 20 datasets of the truth effect. #lme4
Main conclusion:
"GLMMs are a theoretically sound and practically robust method and thus superior for analyzing binary judgments in social and cognitive psychology.”

Does it mean that AI/LLMs do not help at education? I personally don't think so. I'm using the AI every day and find it incredibly useful. It would be odd if they didn't help at learning at all. However, the current empirical base does not substantiate strong claims.

We just posted a preprint with a comprehensive meta-meta-analysis of the effects of AI/LLMs on learning.
TLDR:
- 1,840 effect sizes
- extreme between-study heterogeneity
- extreme publication bias
- small average effects (three times lower than usually reported)
