95-105 is going to be the average. Here in this thread you have the issue of selection bias. For one, the more intelligent are more likely to have reliable access to internet and the ability to utilize it effectively for message boards etc. (Working at a public library I see many people every day, and not only the elderly, for whom even simple technological literacy is a real challenge - and they are of average intelligence). You also have the selection bias from the simple fact that few are going to be willing to admit they scored poorly on the test. One doesn't brag about getting a C or D, but about getting an A. The mean and median (on a bell curve) on a statistically reliable IQ test, as administered by psychologist or school counselor, etc. will always be 95-105 - 100 is the peak of the bell curve for the test - that's the way they were created. If the curve moves off that center point then the test is inaccurate and/or unreliable.
