I wish more people had the time and/or inclination to fact-check what they believe and pass onto others. How many plausible claims for or against candidates did you fact check this election cycle and how much time did you spend doing it? I stop short at name calling because the truth is I spent hours trying to verify certain claims and most voters don't have that kind of time. It's inundating to try obtain reliable facts and evidence from a credible source.
The question in my opinion is does Facebook profit from turning a blind eye to the kind of polarizing self-affirming material and the feedback-loop of a bubble they create for their users because it keeps them in-house? If they do profit from this and Facebook is the sole source of news for an increasing number of adults what, if anything, can or should be done?
