> have an average IQ of 100... I am going to assume good faith. 100 is the definition of average IQ.

  IQ is influenced by education. An illiterate farmer is likely to score worse on an IQ test than someone with a high-school education. If you do transnational IQ studies, you can still calibrate the test to give an average of 100, but countries where the population consists mostly of illiterate farmers are going to have a lower average than countries where almost everyone went to school. That does mean that 100 is a somewhat arbitrary cutoff to require. A better criterion would be what percentage of the population has the education necessary to retrain for a manufacturing job quickly.

    By definition, IQ averages 100 across a population. What you are talking about is how people respond to IQ testing which is inherently culturally biased.

      For any particular IQ test, there can only be one population for which it is perfectly calibrated to yield an average of 100. Other populations e.g. in different countries will have different averages. And of course the whole point of IQ tests is to be culturally biased, since it's about performing well on a particular set of tasks at the exclusion of others. If the illiterate farmer wanted to find out how smart someone is, they'd probably use completely different criteria.
