But first, what is it about this that makes me think of bovine flatulence? Well, everything. Scientists spend millions of taxpayer dollars studying the methane which comes out of the academic end of heifers, reportedly because such gaseous discharge contributes to global warming. Whatever their reasons, they think it's important work. They either don't mind that their research stinks — literally — or they think all of their efforts are worth the money poured into them. And while words like gassy, insubstantial, and malodorous certainly apply to the Berkeley study, there are two chief differences between the study of cow flatulence and this study of conservative psychology. First, the cow-scientists can claim that there's a legitimate purpose to their pursuits. Overblown or not, global warming is something scientists should study. Secondly, while the earth-sciences folks are primarily concerned with what rises up and away from the back end of a bull, these bozos at Berkeley are 100 percent committed to studying and disseminating what plunks to the ground when it leaves the same anatomical disembarkation area.
