The Impact of Social Media Echo Chambers on Political Polarization
Quick fact
According to a 2015 study, Facebook users were about 15% more likely to encounter content from politically like-minded sources than from opposing ones, and algorithmically curated feeds were 5% more politically homogeneous than what users would have seen if they had scrolled through all content chronologically.
Why this is interesting
You scroll through your feed and it feels like everyone agrees with you. But are you really seeing the whole picture, or is an algorithm quietly building a bubble around you?
