Algorithms on social media pick what people read. There’s worry that social media algorithms are creating filter bubbles, so that they never have to read something they don’t agree with and thus cause tribal thinking and confirmation bias. A filter bubble is your own personal universe of information that’s been generated by algorithms that are trying to guess what you’re interested in. And increasingly online we live in these bubbles. They follow us around. They form part of the fabric of most websites that we visit and I think we’re starting to see how they’re creating some challenges for democracy.
