[Remember, I haven’t independently verified each link. On average, commenters will end up spotting evidence that around two or three of the links in each links post are wrong or misleading. I correct these as I see them, and will highlight important corrections later, but I can’t guarantee I will have caught them all by the time you read this.]

 

1: A link between childhood “screen time” and attention problems has - say it with me - failed to replicate. The paper is especially interesting for using a “multiverse analysis”:

We evaluated 848 models, including logistic regression as per the original paper, plus linear regression and twoforms of propensity score analysis. Only 166 models (19.6%) yielded a statistically significant relationship between early TV exposure and later attention problems, with most of these employing problematic analytic choices.

If I had the energy to look through 848 models and see which ones got significant findings and which ones didn’t, I bet I would become enlightened by the end of it.
