6 reasons why couples post their lives on social media

People who post more often are more likely to be psychopathic and narcissistic.

A survey of 800 men ages 18 to 40 found that "narcissism and psychopathy predicted the number of selfies posted, whereas narcissism and self-objectification predicted editing photographs of oneself posted" on social-media networks. Another study discovered that posting, tagging, and commenting on Facebook is often associated with narcissism in both men and women.
