Geosociology

Geosociology is a branch of social/earth science which studies the effect geology has on the behavior of individuals and populations of individuals. (Not to be confused with Sociogeology, which is a unrelated field of earth/social science that studies the effects individuals and populations of indivduals have on geology.)

I took a sociology class once, and the proffesor related the following discovery (I must take credit for filling out the details about the circumstances of the discovery which I found out by deducing from some logical deductions):

There was a town in Texas that had low domestic violence rates. Being Texas, this anomaly peaked the interest of a sociologist who happened to be watching an episode of Nova about geology while pooring over domestic violence stats that was related to the doctoral dissertation they were doing. His or her wristwatch alarm went off, signaling it was time to take their daily lithium dose, and one of those Eureka moments happened that changes the world forever, except for the changing the world part. It occured to this artificially well-adjusted sociology grad student that there must have been a natural geological source of lithium in this Texas town that was leeching into the water supply, hence the lower domestic violence rates.

And thus Geosociology was born.
