James Thompson summarizes an article on the IQs and criminal records of all 21,513 males born in Finland in 1987:I’m guessing the X-axis is demarcated in 9 stanines, but I can never remember what stanines are. (They are half of a standard deviation .) If so, 1 would be 1.75 standard deviations or less below the mean (IQ of 74 or less) and 9 is 1.75 s.d. above the mean (IQ of 126 or more).

[VDARE.com note: It appears that crime is strongly related to IQ, and researchers in Finland are allowed to notice this, because until recently, everyone in in Finland was Finnish. ]
