Reinforces my belief "actual" IQ is not testing much beyond recall for some culturally specific forms of problem solving and question.<p>(I've refused to take an IQ test since about 1970. The fact schools couldn't enforce it I find reassuring to my underlying thesis here. At the time I stopped, some obviously incredibly smart people in my school aced them and some people with thinking issues did poorly so I would believe they measure well at the extremes, but for happy mediums like me the fine distinction of grading is arbitrary)
