In practice there is a bump/right skew where gaussian distributions fail to predict high IQs, meaning more than 50% of people are actually below average intelligence.
The strict definition of "IQ 100" is the median of all humans - i.e. literally 50% of the population is less smart than the median, regardless of whether it's a symmetric distribution, the other 50% to the right. Half of the time at least, when the number of humans is an even number, and assuming that nobody has exactly an IQ of 100.
