Back in 1964, Dr. Erwin O. Strassmann of Houston kicked up a controversy by suggesting there was a correlation in women between bust size and I.Q. And he managed to get his opinion published in a peer-reviewed journal.

Curious to see exactly what he said, I tracked down his article. Turns out he was an enthusiastic follower of the now-discredited theory of "constitutional psychology."
This was an effort to establish a link between body type and personality traits. Critics have dismissed it as an extended exercise in dressing up cultural stereotypes (such as, if you're overweight, you're lazy) in scientific language. For devotees of weird science, the entire field is a goldmine of strangeness.
