Can Your Personality Pass the Smell Test?

Move over Myers Briggs and make room for the nose. Medical Xpress reports that, according to a new study, people can often guess the personality of another person just by smelling them.

Researchers at the University of Wroclaw broke their subjects into two groups. Members of the first group were given personality tests, and then asked to wear the same t-shirts for three nights in a row while sleeping, all the while avoiding soaps or fragrances that would cover their natural scents. Afterward, the second group was asked to smell the shirts and guess the personality of the wearer. As it turns out, the nose is able to sniff out certain personality types–such as extroversion, nervousness, or dominance–about a third of the time.  Participants who did the smell test were at least as likely to be able guess personality traits as subjects in a previous study who made predictions after watching people interact on video. It gives new meaning to the old saw about keeping your nose out of other people’s business.

This study was published in the European Journal of Personality.

    A study says that the nose knows
    Personality type by sniff.
    Extro or introverted shows
    Just by taking a good, long whiff.
    Maybe a wedding should include
    A ceremonial smell test,
    To vow that bride’s and groom’s exude
    Have been compatibly assessed.
    Maybe when world leaders do meet,
    Their natural scents should be there,
    So that the odors they excrete,
    Flow true and honest through the air.

    To sniff or not to sniff, ’cause tiz
    Stuck into other people’s biz.
