Over at his blog NeuroLogica, the prolific neurologist (get it?  GET IT?) and oligarch of the Skeptic Movement Steven Novella has penned a fascinating history of the pseudoscience of phrenology - you know the one where they tell you that you are going to be an axe murderer from the bumps on your head.  Personally, noe of the many bumps on this rugbyologist's head are the result of internal pressure from my brain.  Instead, they come from large men trying to violently knock me off my feet.

Not only does Steve have expertise in the function of the brain,but he also writes a snappy conclusion (but read the whole thing first people):

Phrenology is certainly an interesting notion from a historical
point of view. It emerged out of a largely correct view of
neuroanatomy, but then became rooted in clinical practice even while
continued progress in neuroscience was rendering it obsolete. Its
originator - Gall - combined legitimate basic science with hopelessly
naive clinical claims. He can hardly be blamed, as clinical science had
not yet been developed and accepted.

Phrenology persisted long past the time that it had been rejected by
the scientific mainstream, as practitioners were reluctant to abandon a
lucrative procedure, but eventually science won out. By that time it
had evolved into just another manifestation of divination through cold
reading, and so it is no surprise that it survives as just that

I love the use of the subtly disparaging term "notion".  Well played, Steve.  Well played.
