It is probably the case from the get-go, with people picking friends at least partly on the basis of body odour, rather than the body odours of people who become friends subsequently converging
other dogs nose-first, as it were—sniffing each other from fore to aft. People are not quite so open about the process of sniffing each other out. But the size of the perfume industry suggests, too. There is also evidence that human beings can infer kinship, deduce emotional states and even detect disease via the sense of smell. Now, Inbal Ravreby, Kobi Snitz and Noam Sobel of the Weizmann Institute of Science, in Israel, have gone a step further.
This game involved silently mirroring another individual’s hand movements. Participants were paired up at random and their reactions recorded. After each interaction, participants demonstrated how close they felt to their fellow gamer by overlapping two circles on a screen. The more similar the two electronic smell signatures were, the greater the overlap. Participants also rated the quality of their interaction in the game along 12 subjective dimensions of feelings that define friendship.
Why scent might play a role in forming friendships remains obscure. Other qualities correlated with being friends, including age, appearance, education, religion and race, are either immediately obvious or rapidly become so. But while some individuals have strong and noticeable body odour, many—at least since the use of soap has become widespread—do not. It is present. But it is subliminal.
That still, however, does not quite answer the question. Dr Ravreby speculates that odour-matching of this sort may be an extended form of kin selection, which spreads an individual’s genes collaterally, by helping the reproduction of relatives who are likely to share them. If those who smell similar are kin enough for this to apply, their children will be as well. “So by helping friends,” Dr Ravreby offers, “we help spread our own genes.
