A social scientist presents evidence to support his claim about how social media shapes political perceptions among voters.

Social Media can negatively affect a person's way in which they feel about themselves - much less, someone or something else.  Some people believe everything they read and they believe if it is on the internet then it must be true.  Sometimes we try to compare ourselves to what we are reading about.  We wonder if we look like this - we wonder if we should vote like this or that, based on what our friends and family say.  There is so much propaganda and fake news out there, but people really believe it.  Social Media can make you feel dissatisfied with yourself - or make you think that you have to be like others and think like others to be successful.  

Explanation:

People should not always trust the press.  Do not believe everything you read about politics and the world - they are saying what they think they want you to hear.  They are trying to sway you with pretty pictures and good news.  There are a lot of "falsehoods" about the politicians out there on the internet.  I will admit that FB has attempted to get rid of some of the fake news, but in reality, who can you trust.  You cannot trust FB.  They are also going to give to you and your accounts what they want you to see and to think.  Quit being a zombie and think for yourself.  Use empirical evidence.  This evidence - can be verified.
