    This is the problem with small sample sizes, which is why we have standard deviation. Given that IQ is on a normal curve (it is) and we have a large sample size (we do), the deviation is going to be very small.

    So, very very close to 50% of the population is below average intelligence.

      Let’s keep in mind modern IQ tests scores are normalized to a normal distribution with a mean of 100 and some fixed standard deviation on purpose (15? can’t remember), so of course they’ll fit a normal curve, they are literally made that way.

      I’m also admittedly extremely skeptical of IQ as a measure of general intelligence. It’s not like we have a shortage of high IQ morons out there. It’s a decent estimate of relative intelligence in certain areas, most notably of logical thinking, at best.
