    Remember that half of the population is below 100 IQ and producers want them to buy tickets

    You’re confusing median and mean my friend. IQ is adjusted so that population mean will remain at 100. This does not mean that half of the population is below 100/above 100. As UnderpantsWeevil says, what it means is that ~68% of the population is with one standard deviation - iirc, 15 for IQ. So most people are between 85 and 115.

    If you had a median IQ, a median is the data point that is in the exact middle. If you knew the median IQ you could make your “half of people have a lower IQ than X” claim.

    The other issue is that IQ has extremely questionable validity as a measure of intelligence. Gardner’s multiple intelligences model is more useful for understanding intelligence, but doesn’t give us easy magic numbers to deal with.
