Since we're looking at old news, this seemed relevant.

Quote:Indeed, the conservatives did rate the traditional golf and marriage jokes as significantly funnier than the liberals did. But they also gave higher ratings to the absurdist “Deep Thoughts.” In fact, they enjoyed all kinds of humor more.

“I was surprised,” said Dan Ariely, a psychologist at Duke University, who collaborated on the study with Elisabeth Malin, a student at Mount Holyoke College. “Conservatives are supposed to be more rigid and less sophisticated, but they liked even the more complex humor.”

Do conservatives have more fun? Should liberals start describing themselves as humor-challenged? To investigate these questions, we need to delve into the science of humor (not a funny enterprise), starting with two basic kinds of humor identified in the 1980s by Willibald Ruch, a psychologist who now teaches at the University of Zurich.

The first category is incongruity-resolution humor, or INC-RES in humor jargon. It covers traditional jokes and cartoons in which the incongruity of the punch line (the husband who misses his wife’s funeral) can be resolved by other information (he’s playing golf). You can clearly get the joke, and it often reinforces stereotypes (the golf-obsessed husband).

Dr. Ruch and other researchers reported that this humor, with its orderly structure and reinforcement of stereotypes, appealed most to conservatives who shunned ambiguity and complicated new ideas, and who were more repressed and conformist than liberals.

The second category, nonsense humor, covers many “Far Side” cartoons, Monty Python sketches and “Deep Thoughts.” The punch line’s incongruity isn’t neatly resolved — you’re left to enjoy the ambiguity and absurdity of the reindeer effect or Hambone’s affection for dolphins. This humor was reported to appeal to liberals because of their “openness to ideas” and their tendency to “seek new experiences.”

But then why didn’t the liberals in the Boston experiment like the nonsense humor of “Deep Thoughts” as much as the conservatives did? One possible explanation is that conservatives’ rigidity mattered less than another aspect of their personality. Rod Martin, the author of “The Psychology of Humor,” said the results of the Boston study might reflect another trait that has been shown to correlate with a taste for jokes: cheerfulness.

“Conservatives tend to be happier than liberals in general,” said Dr. Martin, a psychologist at the University of Western Ontario.

Considering this board as a petri dish, I'd say the original conclusions hold.
