      Naw, don't want or expect them to be zero. IQ has some predictive power, but just not all of it.

      I'm sorry to be publicly ragging on your analysis but it really doesn't show what you want it to show :/

      No no, rag away. That's what it's there for. Again, I'm not blind to the endogeneity in my kitchen sink model, so just consider the 0 order analysis. The correlation is respectable, but not predominant.

      so--it's pretty tricky trying to isolate the effect of whatever AFQT proxies for, unless you have a strong theoretical model you might SORT of take it as exogenous given the heritability of IQ (that increases with age!) but pretty plausibly lots of childhood effects . . .

      might spring into play eg, your parents are probably high IQ if you are, they are plausibly more likely to be able to provide more opportunities for your childhood environment, etc all of this as a preface to saying: you could (with this data set) come up with . . .

      a sort-of upper bound on AFQT explanatory power for future earnings by (say) looking at age 18 AFQT (did they give it at 18? at whatever year) and and doing a univariate(ish) nonparametric estimation of (income at 40 | AFQT at 18) say, throw these into a RF and pull the R^2

      Replying to @eigenrobot @NickWolfinger

      but, looking at changes in R^2 for all of these explanatory variables with and without AFQT isn't going to get you what you suggested in your analysis, because those other explanatory variables are collectively almost surely quite correlated with AFQT

      Replying to @eigenrobot @NickWolfinger

      that is to say, your R^2 = 0.48 probably includes a substantial effect from AFQT (or whatever that proxies) simply mediated by those other, plausibly-downstream variables so getting only a 0.02 R^2 increase from adding it doesn't mean its explanatory power is so limited

      Replying to @eigenrobot @NickWolfinger

      the other issue is that unless you're being extremely aggressive about model specification and didn't mention it, your RE panel is not going to pick up the full plausible explanatory power of your variables in the way that a more flexible model class would

      there's also the overfitting that comes with trad econometric methods that don't take advantage of modern regularization techniques, but that's a problem in the other direction anyway I guess my message is something like "be very careful interpreting R^2 and changes thereof"

          thank you for coming to my unhinged ted talk :) and please do accept my apologies for the initial exasperation, this is at an intersection of about twelve personal betes noires 😔

          No worries. I was responding to my own bete noire--IQ EXPLAINS EEVVVEEERYHTINGGG--in about an hour. I realize that my multivariate model isn't the strongest test possible....
