Is the internet a polarizing force?
I have seen where a lot of people claim that the internet has caused people to seek out- "self select"- only those voices who they agree with and exclude opposing views. This, supposedly, causes "us" to be less likely to experience differing points of view and makes confirmation bias almost unnecessary because we hear nothing but what we want to hear. I seriously doubt this.
I don't know about you, but for me the internet has exposed me to points of view radically opposed to my own (both past and present) that I would have never heard had I never gotten online.
I have also noticed that people who I have known for years who are online a fair amount have had a greater change in their overall attitudes on different issues than those who hate the internet (or avoid it for whatever reason). I don't think this is a coincidence.
Every controversial idea I espouse meets with opposition at some point, and I am constantly disagreeing with someone on some site. In "real life" I never debated politics or religion even when I was thinking the other person was completely off their rocker- preferring just to stay silent for the sake of peace. How many times did others do the same for me? On the internet, for good or bad, this doesn't happen. If you claim "liberty is better than slavery" someone is bound to vigorously type "BS!".
I'm not sure where all these people are who have managed to find corners of the internet that only feed their already dearly-held convictions, to the exclusion of everything else, but that isn't my experience. Not by a long shot.
It makes me suspect the agenda of those who make the claim that "the internet is polarizing society".
