There is a well-known bit of epidemiological jiggery-pokery known as the data dredge. What you do is get a set of statistics for the incidence of some disease or condition, and then you correlate it against as many other data sets as you possibly can. Do this enough times and you will find one that violates whatever null hypothesis you have chosen. You then write up some flimsy paper, leak the result to the Daily Mail, and bask in the glow of reading: “Ingrown toenails linked with eating blancmange, scientists say.”

But maybe it’s about their parents. If parents are less social, outdoors types, maybe they don’t mind living somewhere with a lot more rain?

Yet another cum hoc ergo propter hoc logical fallacy. Correlation does not equal causation

If Florida used the same diagnosis method as Washington State I am sure some researcher will link Autism to hurricanes and global warming. ;0

Could be lower light levels (seratonin), higher humidity, the sound of rainfall, umbrellas, interaction between pollution and rain, methane from rotting vegetation (higher in wet areas?) who knows.

Sheep’s bladders have been known to prevent earthquakes, after all.
