This video about the problems with The Bell Curve (a book about IQ and other things) does a lot to explain a lot of the problems with IQ: https://www.youtube.com/watch?v=UBc7qBS1Ujo https://www.youtube.com/watch?v=UBc7qBS1Ujo. The video is well-researched; I've been a long-time fan of the creator for putting out quality stuff. >and it definitely has a large genetic component There's a number of studies showing that IQ is "heritable", but this is different from saying it's genetic. The video above (around the 39:00 mark) and https://apcentral.collegeboard.org/courses/ap-psychology/classroom-resources/understanding-heritability https://apcentral.collegeboard.org/courses/ap-psychology/cla... both get into this point. Wearing earrings is highly "heritable" despite being an arbitrary social custom, and having 10 fingers is not "heritable". It's also important to avoid falling into the conclusion that many people take about IQ that it being heritable means that educational efforts to improve it are worthless: >Think about the relative heights of men in a poor village in an underdeveloped country 100 years ago. The average height for these malnourished men might be 5 feet 2 inches. The heritability in observed heights within this particular society can be quite high; men of tall fathers are on the average considerably taller than men of short fathers. However, this does not mean that a program of improved sanitation and nutrition could not significantly raise the average height of this group in a few generations.
