Taking a single statistic on something as complex and multivariate as "intelligence" is already discarding a lot of information. When you throw in social factors (Who is writing the tests? What are the challenges faced by the various populations taking the test?), it becomes utterly absurd and unscientific to conclude that your statistic is free of some systemic source of error.

If IQ tests were presented in, say, a physics context as a serious experiment, the presenter would be laughed out of the room. Taking them seriously and uncritically indicates nothing less than a complete lack of understanding of how the scientific method is to be carried out and how its results are to be interpreted.
