All Politics Is Olfactory

By PETER LIBERMAN and DAVID PIZARRO

JUST days before New York’s Republican gubernatorial primary, Carl Paladino mailed out thousands of campaign ads impregnated with the smell of rotting garbage. Emblazoned with the message “Something Stinks in Albany” and photos of scandal-tainted New York Democrats like former Gov. Eliot Spitzer and Representative Charles Rangel, the brochure attacked Mr. Paladino’s rival, former Representative Rick Lazio, for being “liberal” and a part of the state’s corrupt political system.

At first glance, the revolting scent seemed like another attention-grabbing stunt from Mr. Paladino. But recent research on disgust suggests that the odor may have had additional, hidden effects on the 200,000 registered Republicans who received the brochures.

The emotion of disgust, many researchers believe, evolved to protect us from contamination. It is easily elicited by feces, pus, vomit, putrid meat and other substances linked to pathogens. A single picture, a few choice words and, yes, a slight odor can elicit a surprisingly intense reaction.

Disgust’s origins as a protector against contamination can be seen in its characteristic and universal facial expression: the wrinkling of the nose, curling of the upper lips and protrusion of the tongue. Wrinkling the nose has been shown to prevent pathogens from entering through the nasal cavity, and sticking out the tongue aids the expulsion of tainted food and is a common precursor to vomiting.
