Posting selfies on social media can reveal a person's personality and self-image. Research has found that the positivity in selfies is related to extraversion and agreeableness, while duckface selfies are associated with narcissism. People who score higher on self-objectification tend to post more selfies, which leads to more feedback from friends online, encouraging them to post even more photos of themselves. Narcissism is also associated with frequently posting gym selfies. Additionally, the type of selfies a person posts can indicate their personality traits. For example, people who post selfies in which they are dressed to impress are more likely to be self-disciplined and enjoy orderliness. Overall, posting selfies can be a way for people to control the image they project and receive positive feedback from others. However, it can also contribute to social comparison and feelings of inadequacy.
