Maybe, yeah, but I kinda get annoyed at this kinda dismissiveness - it’s a type of vague anti-science or something like that. Like… Sure, overfitting is a potential issue, but the answer to that isn’t to never fit any curve when data is noisy, it is (among other things) to build solid theories and good tests thereof. A lot of interesting stuff, especially behavioral things, is noisy and you can’t expect to always have relationships that are simple enough to see.

You’re probably right. But also, I was annoyed, not trying to convince. Maybe not the best place to post from. :)
