The stench of a liberal...

The stench of a liberal...  Really?  I'm skeptical, but this study claims to show that humans can detect the odor associated with one's political beliefs.  I'm skeptical on several levels.  The idea that political beliefs cause us to excrete different chemicals seems rather far-fetched on the face of it – I'd want to see the chemical compounds identified before I accepted that.  Further, personal experience suggests (rather strongly) that most people's political beliefs are ill-formed in the first place – that is, most people don't actually think very much (or very hard) about politics at all.  If there was some association between stench and politics, you'd expect most people wouldn't smell at all...
