Economics 101

So, I create a study that looks at the effects of the sale of umbrellas and rainfall. Wow, my study finds a high correlation between the sale of umbrellas and rain coming down!!! Buying umbrellas makes it rain, right?? No.

Just like "being a member of Oprah's book club" doesn't make you vote for Sen. Obama. People that are more likely to be members of Oprah's book club, were also more likely to be Obama supporters. The study itself doesn't include correlativity data, probably for this very reason.
