Stupid Correlations

Correlation doesn't mean causation, but most people see correlations as causative when they fit their pet theories anyway. If you need a better rejoinder to someone's correlation than '93.7% of statistics are made up on the spot', there's a website for this! correlated.org contains gems like:

15 percent of people who dislike mayonnaise are good dancers, compared with 29 percent of people in general.

75 percent of people who can't type without looking at the keyboard prefer thin-crust pizza to deep-dish, compared with 59 percent of people in general.

61 percent of people who floss regularly prefer credit cards to debit cards, compared with 45 percent of people in general.
