Justifying racism using “science” isn’t new, by any means. Every few years, it appears that someone needs to provide a rationale for bigotry, so they publish some sort of madness and hope most of the readers suffer from scientific illiteracy. The problem is that even with a thorough debunking, people latch on to articles like this to confirm their own biases. So, if you are suddenly confronted with racist foolishness masquerading as science, here is how to respond. Since it’s here, let’s use the Psychology Today article (available in full here) as an example.
Look at the Methodology
Whenever you hear the word “study,” start checking for the methodology. Oftentimes, a methodology will reveal more about the study than the summarized results.
A good example of this is a study we were alerted to a year or so ago. The Daily Mail covered a scientific study which proposed that racism may be hard wired into our brains. However, there was an obvious flaw in the study:
All the viewers were white but the researchers believe the results would still have been similar with any other group.
Now, this study wasn’t using basic things, like a sample representative of population. Yet the study authors felt confident in applying the results to everyone.
The same issue pops up in Satoshi Kanazawa’s piece. He actually doesn’t refer to his own research, but another study. And he doesn’t link to the other study, assuming that all readers will know the term “Add Health.” What he refers to is a rigorous, national study…about teen development and health.
The National Longitudinal Study of Adolescent Health (also known as Add Health, the Add Health Study, and the Add Health Survey) is a nationally representative study originally designed to examine how social contexts (such as families, friends, peers, schools, neighborhoods, and communities) influence teens’ health and risk behaviors. The study is now examining how health changes over the course of early adulthood. [...]
