[1]There is a sign in the subway that explains New York completely. “NYC: tolerant of your beliefs, judgmental of your shoes.” We are open to many walks of life, but your shoes … well, that’s another story. Researchers at the University of Kansas say that people can accurately judge 30 percent of a stranger’s personality simply by looking at the person’s shoes.
[2]The study involved volunteers filling out a personality questionnaire and providing photos of            ______that they most frequently wear. Then 63 students looked at the photos and were able to accurately guess the volunteers’ gender, age, social status, and even whether the owner was extrovert or introvert, liberal or conservative, and their degree of emotional stability and openness.
[3]Here are some interesting findings from the study. Practical and functional shoes generally belong to agreeable people. Ankle boots belong to those with more aggressive personalities. Uncomfortable looking shoes are usually worn by those with calm personalities. Those who are most worried about their relationships wear brand new or well-kept shoes. This is because they are worried about what others think of their appearance. Liberals wear less expensive shoes. The more boring the shoes are, the harder it is for the owner to form relationships. This is because he doesn’t care about what others think of his appearance.
[4] “Shoes convey a thin but useful slice of information about their wearers,” the researchers of the study said. “Shoes serve a practical purpose, and also serve as non-verbal cues with symbolic messages. People tend to pay attention to the shoes they and others wear.”
[5] The researchers noted that some people would choose shoe styles to hide their actual personality traits, but they also noted that volunteers were likely to be unaware that their footwear choices were revealing deep insights into their personalities.
