PsyBlog featured a new research study on facial evaluation and the power of a smile. The study found that when judging men just on their facial appearance, there was a relationship with actual intelligence. But when it came to judging women, there was no relationship between how intelligent they were perceived and their actual intelligence. The study suggested that this is because women are primarily judged on their attractiveness overruling perceptions about intelligence.
Interestingly, the study also found ‘high intelligence’ faces appear to be smiling more than the ‘low intelligence’ faces. A similar pattern was described for the perception of trustworthiness.” In the other words: frown to look more stupid and smile to look more intelligent. ~Jeremy Dean, PsyBlog
