the paradox of selection: the purity of your selection-pressure is inversely proportional to its strength.
sorta obvious when phrased that way, but the point is that you can increase your selection-pressure over the true target by additionally selecting for increasingly less precise proxies. this increases the rate of true-positives and decreases false-negatives, but it also increases false-positives (confounders), and sometimes at a higher marginal rate.
- the highest-avg-IQ academic subjects are mathematics and philosophy *because* they're also *less* financially profitable (thus, ppl go into them bc they're rly intellectually interested in them). the statistics doesn't seem to bear this out, but that's bc there are confounders—the underlying pattern still holds. :p
