>Since when is the simplest possible example of the fallacy of division the same thing as “logic”? Without any additional information the assumption that entropy rules the day is "logically" reasonable. Meaning that if out migration and in migration is random the proportion of High IQ people moving out and in will be random and on par with population proportions. Trust in entropy and probability is a completely reasonable and logical assumption to make. In fact, our entire scientific establishment is built on these axioms. To assume a random correlation exists out of nowhere is the unreasonable claim. Don't twist words and make it sound illogical. It is illogical to think otherwise without presenting new evidence and a new claim. So what you did here is introduce a new claim. You say there is a mechanism effecting natural entropy and that more intelligent people could be migrating in. This is not an illogical claim, but it is an extraordinary one. If you were to make such an extraordinary claim. You need to provide equally extraordinary evidence as this trend isn't on the front page of every news organization. So you say more higher income people tend to migrate into California and lower income people tend to migrate out. Do you have a source? Additionally I would like to know whether the standard deviation between the correlation of income and IQ fits with the incomes of people migrating out and into California. That would be strong evidence for "Brain Gain" if the trends show more intelligent people migrating in. At this point I acknowledge your claim as a possibility. But the evidence you present (essentially no evidence, just a claim that evidence exists) makes it fuzzy enough that it is equally likely that natural entropy takes precedence here. There is also a lot of anecdotal/qualitative evidence working against your claim including coworkers who are moving out, more and more tech companies offering remote options and such and such. It looks to me that you aren't really making a claim but your just being pedantic towards my "logic." I can slightly acknowledge the possibility there isn't Brain drain here, but let's be real. Until there's a study specifically targeting this theory it's just a random shot in the dark.
