If you're conscientious
Hard workers stand out.
A study from the University of Liverpool found that participants were able to gauge people's conscientiousness levels pretty accurately by glancing at their photos.
In the first part of the study, the researchers had a group of nearly 200 participants rate themselves on personality traits, including conscientiousness, then took photos of them.
Using photos of the people who said they were the most and least conscientious, the researchers created composite images of an accordingly highly conscientious person and a highly unconscientious person. They followed this procedure for four other traits.
Next, they had a group of people look at the composites and rate the imaginary people on those traits. Participants were able to accurately detect which face belonged to people with varying degrees of all of the traits.
