What is it about social media that makes teenagers abandon all common sense, reason and logic?

They may trust too much. It may be those damn raging hormones. Social media tends to make people expose too much. Is it competition? Is it jealousy? Is it naivete? It is likely those combined and more. I bet many live and learn hard lessons and then they think what was I thinking? There needs to be more education about things involving social media. This includes bullying, pedophilia, sex rings, etc.
