"BTW, Genuius is 130."

I don't think so.

Last I checked (the upper range of the IQ scale):

up to 115 is "normal"
116 - 139 is "superior"
140 - 149 is "gifted"
150 - 200 is "genius"

I haven't seen the list since about 1985, so this may not be exact, but it's close.

Keep in mind, this scale is on a bell curve. So while the upper range may appear quite large numerically, the number of people who actually test in that range is quite low by comparison.

I suspect you're misremembering: IQ tests are normed to have a mean of 100 and a standard deviation of 15. None of the properly normed IQ tests is sensitive to differences out beyond 4 standard deviations, so reporting IQs above 160 or below 40 is one of those statistics that fits into the sequence 'lies, damned lies, and statistics'.

That said, 130 as a cutoff for 'genius' is a bit low, surely 145 at least.

(My wife does work in psychometrics, among other things, so I know these things.)

Haven't paid a lot of attention for 2-3 decades.
