In Brief
- The human sense of smell is often seen as insignificant, but this sense is keener and more influential on our species than many people realize.
- Smell subconsciously facilitates a variety of human social interactions. People use smell to assess a person’s likability, sexual attractiveness and emotional state. They can also use scent to distinguish a stranger from a friend, a male from a female and someone who is gay from someone who is straight.
- Deficiencies in olfaction may contribute to social withdrawal, such as that which accompanies schizophrenia.
A tangle of tubes and polyurethane pouches binds a naked man and woman—he, paunchy and unperturbed, she, slim and similarly unself-conscious. This setup is not some esoteric sex game; it’s “Smell Blind Date,” an installation created by artist James Auger on display this past spring in New York City as part of the Museum of Modern Art’s exhibition Design and the Elastic Mind. The PVC tubes—which run between the subjects’ chests, with outlets extending to pouches attached to their noses, armpits and genitals—allow the man and woman to inhale each other’s body odor through a wall that divides them. In theory, they are on a truly blind date, each undistracted by the other’s looks, assessing the other’s potential as a mating partner by his or her smell alone.
The human sense of smell is often seen as insignificant, dismissed as a distant also-ran to our keen eyesight or sensitive hearing. But this sense is keener and more influential on our species than many people realize. In particular, as Auger’s fanciful art project illustrates, smell facilitates a variety of human social interactions, both casual and intimate. Indeed, people who lose their sense of smell often gain a new appreciation for its importance [see “When the Nose Doesn’t Know,” by Eleonore von Bothmer; Scientific American Mind, October/November 2006].

Add CommentI read with interest how the lack of smell may result in depression. I have anosmia (no smell nor taste) and have had more bouts of depression since. I lost my smell and taste during a respiratory infections, and taking anti-biotics. It has been 7 years.
Reply | Report Abuse | Link to thisIt's extremely frustrating that (1) there's no easy or obvious link to email comments to the editor/author and that (2) the study done by Gottfried is not cited. People who read Scientific American Mind want to read the actual scientific articles mentioned. It's embarrasing that basic documentation of studies discussed in the article isn't provided, even in the "further reading" section.
