Liberals, conservatives, and humor

Jake is about to chip onto the green at his local golf course when a long funeral procession passes by.
From Predictably Irrational, a really fascinating blog on the science of rationality.

He stops in mid swing, doffs his cap, closes his eyes and bows in prayer. His playing companion is deeply impressed. “That’s the most thoughtful and touching thing I’ve ever seen,” he says. Jake replies, “Yeah, well, we were married 35 years.”

Who do you think will find this joke more funny liberals or conservatives?

Common stereotypes link the word “liberal” with words such as open-mindedness, tolerance, and impartiality, while the word “conservative” is linked with tradition, caution, and conventional values. Given these associations we might expect that liberals will appreciate, and respond more to humor and jokes than conservatives. This was certainly our expectation going into this project, but, is this really the case?
