👍 but I think it's far less difficult (and constraining of discovery) than some people think. For example, it's simple enough to preregister a "decision tree" of research designs to be informed by robustness checks.

I'm curious how people view hypotheses about these achievement declines. I incline towards (1) the failure to refine & sustain school accountability & (2) the rise of smart phones & social media. But that's conjectural without better evidence.

My research w/ @hhsievertsen.bsky.social indicates redshirting benefits kids lacking the self-regulation needed to thrive in more structured classrooms.
That argues for kindergarten-readiness assessments that inform targeted—not universal—responses. onlinelibrary.wiley.com/doi/10.1002/...
