“High church attendance correlates with pricing sanity; low church attendance correlates with pricing insanity.” — is it controlled for coastal impact? Someone who really knows how to intepretate statistics will be very careful and not reach this conclusion so quickly. But if you do want to make these correlations as causal factors (well, I’m disappointed that a U. Chicago graduate is doing this, but maybe that was too long ago for you, as you said:) you can also say that low church attendence states contribute a lot more to the national economy and tax revenue, and low church attendence states help to pay welfare consumed at high church attendence states; and people at low church attendence states are better educated than people at high church attendence states…the list goes on. Better mention them all, and make church attendence be responsible for all.
