Yeah, I remember that rule of thumb (Int = IQ/10) from my 1E days...but I've recently discovered that it just doesn't mesh with reality.
On a straight roll of 3d6, one out of 216 people would wind up with an 18 intelligence. (That's roughly 0.5% of the population.) According to that rule of thumb, it means that 0.5% of the population would have an IQ of 180.
However...
I've taken several IQ tests over the years...and consistently get about a 140-145. According to various web sites I've looked at on distribution of IQ scores, that (in theory) puts me somewhere around the 98th to 99+ percentile. But, according to that rule of thumb, I'd only have an INT score of 14 -- and, by the 3d6 bell curve, a 14 or more would be scored by, I think, (31/216) 14% of the population.
