an IQ of 100 is average
Apparently 90% of people are between 85 and 115.
Only 5% are below 85 and 5% are above 115.
I don't know that it was official or anything, but I recall doing some sort of IQ test and getting like 123 or something, but that was probably not an indicator of my actual IQ.
And IQ's not a real indicator of anything substantial anyway.
