 Certain personalities have a smell: study European study says scent can reveal details about personality 
 
 This puts a new spin on the old saw about passing the smell test. According to an upcoming study published in the European Journal of Personality, people can make accurate judgments about another person's personality based on the way he or she smells. In the study, Polish researches asked raters to sniff white-cotton T-shirts that were worn for three consecutive nights by 100 men and 100 women who had taken personality tests. Though the sniffers didn't nail it every time, they were able to predict whether the shirt donors were outgoing and extroverted or neurotic and anxious about as accurately as other raters who predicted personality traits after watching a video, researcher Agnieszka Sorokowska told MyHeathNewsDaily. Judgments of dominance were most accurate in the case where an individual rater was assessing the odor of someone who was the opposite sex, suggesting such judgments are especially important when it comes to choosing a mate, the researchers said. The findings are preliminary and more studies need to be done to confirm the results, Sorokowska said.
– You are what you reek? It turns out that we can tell a lot about someone's personality just by their smell, according to the New York Daily News. Sixty people in Poland wore the same T-shirt for three nights, and did not use soap, smoke, drink, or "eat odorous foods" during the study. Those shirts were then sniffed by 200 lucky volunteers, who were asked to judge the smells based on five personality traits, such as extroversion, neuroticism, and dominance. The results weren't perfect, but the smellers' predictions about extroversion and neuroticism were about as accurate as those of raters who made their judgments after watching a video. MyHealthNewsDaily notes that the smell-testers did especially well in detecting dominance in members of the opposite sex.
