The study also found that many people who take selfies and post them immediately and directly on social media demonstrate a lack of impulse control. It makes sense, and actually makes up an entire branch of psychology. However, many non-narcissistic people also spend a lot of time editing their selfies. This behavior is described as auto-objectification. Auto-objectification refers to a state of being where physical appearance becomes a part of your personality that you highly value. People in this state build their self-esteem on their physical appearance, rather than their accomplishments or abilities.
