Of course there is such a thing - cook up a tech talent score based on these test results (see my other post on that topic) and then measure a group's mean, sigma or credible intervals.
How society is organized may be a cause for a group having higher/lower technical talent (so might "intrinsic" features, i.e. things not mutable by "society"), but it doesn't mean that talent doesn't exist.
