Correlation Does Not Equal Causation

I've been posting a lot recently...must be a finals week phenomenon.

But a few weeks ago I was watching an old Frontline episode about the conflict over vaccines and autism. (you can watch it here)

The biggest take home message is something most scholars are familiar with: "Correlation does not equal causation." And funnily enough, today I came across this from business week. It amused me. (click on the picture to see all six graphs in full size)

And in 14 hours I'll be starting my environmental health final! And in 16 hours I'll be done with the semester!
