Phrenology is a form of character reading, supposedly divined by reading the contours of one's head.
My friend, the late Robert McCoy, operated the Museum of Questionable Medical Devices in Minneapolis, MN. On a visit there (when I was speaking at the 2000 conference of the American Physical Society, held March 20-24), I visited Bob who promptly insisted with a grand smile, "You need to have your head examined."
He fitted me with the head-measuring device of the Psychograph, a machine that printed out a list of my supposed mental traits and their numerical values (e.g., "4 Sympathy-Superior"). Merely pseudoscientific fun, but a fond memory of "the real McCoy."
