A population is whatever the individual researcher is interested in.That always seemed simple to understand. If you could IQ test an entire population, the average score Would be designated IQ100. But what constitutes a population?The average IQ of a population is exactly 100, by definition.
A country’s total inhabitants? The world’s? Including age-adjustments or only adult scores? If only adult scores, what’s an adult? If not, what is the age adjustment algorithm?
IQ is meaningless except as a measure of an individual’s ability to perform on IQ tests.
But the stupidity of the average human is a self evident objective reality that doesn’t need to be quantified.
A large fraction of studies are done on entire nations, or the entire world, and so there's a tendency to think of 'population' always referring to those groups; But it's perfectly legitimate to define a population in any way that suits your research - and no matter how you define a population, that population has members each with their own IQ, and with an average IQ of 100.
