From my book review in Taki's Magazine:
It’s a strange totem of the 21st century that if a brain scan can show us where something would happen inside the skull, we can therefore make it happen in ourselves; and also, hesto presto, we can fix African-American dysfunction by somehow making it happen in their brains.
We don’t think this way about other organs, though. Consider the stomach. For a century or more, we’ve had a more than adequate knowledge of how the digestive system works. Yet on average we’re fatter than ever. Why? Not because the science of stomach scans hasn’t progressed enough, but because we like eating more than we like exercising.
Read the whole thing there.
