I thin iq is bs and asian iq being high is circumstantial. All iq tests are based on pattern recognition and simple math. Asian cultures use angled graphics which could mean they are more exposed to visuals that are used in iq tests whereas whites use round graphics in their cultures so in iq tests they rely more in actual intelligence eather than visual pattern recognition. Proof is in how large disparity is between development of white vs asian societies throughout history.
Vietnam, Thailand, Laos have a lower IQ than Japan, South Korean & China
People I have met from these lower IQ Southeast Asian cultures are better at trade school skills like carpentry and know gardening, camping and wilderness survival type skills better but are not as book smart
If I was stranded in the wilderness I would rather be with one of these wilderness smart people than book smart people
Urban blacks are usually bad at book smarts and also do not know wilderness survival
