This is the first of three guest posts by Professor Jonathan Kaplan of Oregon State University. Professor Kaplan is a noted philosopher of biology who has published extensively on biological race and IQ among other topics.
Part One: Introduction and Misleading Comparisons
In this series of blogposts, I discuss three relatively recent papers that, in one way or another, defend the so-called hereditarian hypothesis – the claim that genetic differences between human populations identified as ‘races’ are causally responsible for realized differences in cognitive abilities as measured by I.Q. test-taking ability, in a straightforward way via developmental effects on e.g. neurobiology (rather than through e.g. racism and the legacies of racism associated with racial ascriptions). But my main point in these posts is not to engage directly with the arguments put forward in defense of that hypothesis; these have been confronted many times before, and found seriously wanting. Rather, my goal is to think more about the structure and stated aims of those papers, and the ways in which the papers fail to take seriously their responsibility to honestly present their own arguments, and to honestly engage with the relevant literature.
