Beware: If you go to a Fourth of July celebration on Monday, your kids are statistically more likely to end up Republican.
The study, out of Harvard, relates the likelihood of identifying as Republican to the amount of precipitation on the 4th of July. They used rainfall data on all the various July 4ths, between 1920 and 1990 to estimate your likelihood of having experienced a 4th of July parade as a child. The found a significant correlation between July 4th Parades and Identification as Republican.
I love statistics.
