But other studies have found that you can actually smell someone's political beliefs. Politics, it turns out, are crucial to a happy relationship. And, while maybe not consciously, it seems that you can actually tell from smelling someone if they have similar political beliefs as you.
A study had people rating the odor of individuals who were very liberal or very conservative. They never saw the smellees, so it was based on scent alone. And while the smellers couldn't predict who held what belief, they consistently preferred the odor of those with similar political beliefs as themselves.

So while you might think you fell in love with your significant other when you discovered you both voted for Dennis Kucinich in 2008, in reality you might have known instinctively they had the politics for you before you ever even spoke.

Because the fastest way to a woman's heart is deception.
