Correlate This!

The next time someone shows you a graph that purports to explain carbon dioxide as the causes of "Global Warming" or gender discrimination as a cause of salary inequity, just pull out this chart and show them some real correlation. 97%, in fact!


Kudos to Megan McArdle for demonstrating that correlation is not causation.

Or, as we used to say when high schools taught real content: "Oh, that's just a case of the cum hoc ergo propter hoc fallacy."
