I’m baffled at how an African American woman speaking about the economy, climate change, & the like represents an ode to identity politics, as @jbouie avers here. & no, inclusiveness is not a dog whistle for Democrats.https://www.nytimes.com/2019/02/06/opinion/stacey-abrams-state-of-the-union.html?smid=nytcore-ios-share …

I dunno, maybe because African-Americans have an IQ 15 points lower than Euro-descended people, meaning there is no possible equal competitive field between them, so their socio-political interests are fundamentally at odds with each other. Just a theory

You’re also treating IQ as a predictor of, well, everything. Its predictive power isn’t that strong for any outcome variable. It only explains a minority of variation in *anything.* I know that first-hand from analyzing data.

Do you really, seriously, believe this is true? Are you arguing that IQ is a false metric? Or alternately that, within a meritocratic society, intelligence actually isn't important after all?

I'm not talking about racism at all. I'm making a simple empirical claim. Are u guys familiar with a correlation coefficient? I just did 1 with IQ & income for a sample from NLSY79. It's .42. That means IQ is related to $, but other things together matter more. Got it?

So the squared correlation coef. is the explained variation. For my sample, .42^2 = .18. Thus, you can explain 18% of variation in income by knowing someone's IQ. In imprecise terms: 18% of the time u can perfectly predict $ by knowing IQ. Too many other things matter.

I'll respond with more patience than you probably deserve. I'm a professional quantitative social scientist, and I'm telling you what national data say about IQ and earnings. Yes, IQ predicts earnings, but so too do many other things.

Ok then Mr. Professional Quantitative Social Scientist - what predicts earnings *better* than IQ?
