This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.
I will record lectures & all will be found at this link: github.com/rmcelreath/s...

I'm looking for EMA software that can do relative scheduling: participants report a time in their first daily questionnaire (e.g. "woke up at 7am"), then follow-ups trigger x hours after that reported time. I would greatly appreciate any recommendations!

The framing around 'stricter age restrictions' feels disproportionate considering the magnitude of the effects.
I ran some rough calculations: Cohen's d ≈ 0.059 and 0.114 for the group comparisons on the cognitive composite measure.

Everyone knows that temporal contiguity is important for associative learning. As the interval between a cue (e.g., a light) and an outcome (e.g., shock) gets longer, the conditioned response (e.g., freezing to the tone) is acquired less quickly.

😍 Our latest is out now in @commspsychol.nature.com. 🤩 We show with Bayesian modelling and experimental manipulation of uncertainty that developmental differences in social influence depend on differences in the internal uncertainty people have about their choice

Internal uncertainty impacts social information use in risky choice across adolescence - Communications Psychology
Adolescents’ choices are influenced by others. A social risky choice experiment and Bayesian modelling reveal that age differences in internal uncertainty, being unsure how to choose, relate to differences in susceptibility to social influence.
