Walnuts are good for the brain because they look like brains.
Ginko is good for the lungs because the leaf looks a little like a lung, etc., etc. But if you are protein starved walnuts can be good for you and the benefits of Ginko are well known. Anthropologists are quite familiar with this phenomenon. We as historians should be as well. Fallacious is in the eye of the beholder.
