Although it is a slightly upsetting truth to many, physical attractiveness doesn't only matter when it comes to choosing a partner, but also when it comes to a person's employment. My parents are both business people who have always stressed the importance of appearance when pursuing a job, so the concept of the physical attractiveness bias wasn't as a complete shock. Even though I had grown up with this idea, it was still surprising to see how much emphasis was placed of physical attractiveness.
Many studies have shown that there is a distinct attractiveness bias in many work settings which gives people who are more physically appealing a better chance at getting an interview and being hired when compared to their unattractive counterpart. The ideology behind this is that these attractive people are more intelligent, better in social settings, possess better self-control and more self-confident. In recent years the problem of judging an applicant largely based on appearance has started to diminish, but the bias is still an important factor. Although organizations are now looking more carefully at applicants qualifications, if it comes down to two applicants who are very comparable as far as qualification, the more attractive person will most likely be hired.
