How to Argue With a Racist: What Our Genes Do (and Don’t) Say About Human Difference by Adam Rutherford
This 2020 title is somewhat misleading, since author Adam Rutherford is not an expert on antiracist engagement, and even he admits that most people who espouse open bigotry do not appear receptive to evidence-based rebuttals. However, as a leading geneticist, the writer is able to lay out the known facts (and outstanding questions) about human genetic diversity and its intersection with the perceived category of race. The result is a gem of science communication, simultaneously thorough and easy for a layperson to follow.
I thought I already had a basic grounding in this subject from my college anthropology days — race is more a social construct than a biological trait, and so on — but I’ve been pleasantly surprised by how much remains to be said on the matter, and how exactly we can determine that apparent racial traits are due to cultural upbringing and self-identified membership over strict inheritability, from athletic prowess to performance on IQ tests. Simply put, those popular ideas about some particular group having a natural talent for some particular skill or occupation are faulty, and the author skillfully illustrates how these stereotypes bear no actual connection to anything passed along at birth.
Rutherford has a gift for explaining the weird and the counterintuitive about genetics too, like how children can end up with different-colored eyes, hair, or even skin tone than either parent, or how modern descendants from a common ancestor as recent as the eighteenth century can nevertheless be genetically unrelated to one another due to the necessary genomic loss in every successive generation. He also touches on how DNA testing services misrepresent their findings to consumers (no, you are not X% of a specific nationality!), and how anyone’s extended family background should be diagrammed not as a tree so much as a closed loop, with certain individuals occupying multiple nodes (such as the same great-great-great-grandparent on various sides). And of course, he addresses how there has always been contact and sexual reproduction across supposed racial boundaries, giving all of us a more complex heritage than any eugenicist would want to admit.
In all likelihood, this book will not, in fact, equip you to successfully convince a racist that their beliefs are hokum, and I’m disappointed by the name to that effect, which I assume the publisher has given the work. But it is a fantastically accessible introduction to the best contemporary understanding on why race is not genetic and other issues of heritability, for any readers looking for such a primer.
