I am pleased to find that New Scientist has a fuller report of the study I linked to yesterday about “white racism” being detected by brain scans.

Note this comment about how “racism” was measured: “The Implicit Association Test (IAT) is controversial. Gehring says "one must be cautious" regarding any claims that a test is a direct measure of racist attitudes.”

And this comment on what the brain scan shows: “The team does not know exactly why this brain area should light up in people with biases. "They are either trying to inhibit or control something - but we don't know what that something is," she says. "It could be an emotional reaction, or thoughts that come to mind. Or it could be something as benign as simply trying not to make errors."“

In short, they had no good evidence at any point that they were measuring what they said they were measuring.

There are also some further dismissive comments at the end of the New Scientist article.
