Man i hate confirming these kinds of biases. I wish this plot werent true, but it makes so much sense.
The R^2 is trash, this is just a very squished cloud
It's Add Health, so it's not even the R2 that's the problem but the fact it's probably got a ton of covariates not included in the model. Lots of contextual variables not in that set drive me nuts, although I'm not even sure if 5th wave exists or has testosterone data lol (haven't used it in years)
Well, it's also important to note that the variability is high so the prediction for a single individual won't be of much use
That's an easy wish! Last time I saw this plot people were saying that this kind of data doesn't even exist in the mentioned source (that and IQ is kind of bogus, but y'know)
