The notion of cognitive differences isn't that controversial. What's controversial is making value judgements about their utility in critical social contexts.

The notion of cognitive differences isn't that controversial. What's controversial is making value judgements about their utility in critical social contexts. There isn't evidence of an "obviously superior" thought modality for most any given task or family of tasks you can name. What's more, it is a generally accepted fact among scientists that these values exist as distributions among the population (and even this paper demonstrates non-total values). Since we generally think that DNA and extensive physical scanning shouldn't be a prerequisite for social contexts, many of these differences aren't especially meaningful for something like a hiring committee.
