This year's election and its aftermath made one thing clear: There are multiple Americas and we're not listening to each other.

It's not necessarily our fault either. Search engines and social media platforms like Google and Facebook have been accused of creating "filter bubbles" for users, using algorithms to determine what we see based on what they think we want to see, often excluding information that might challenge our pre-existing beliefs or make us feel uncomfortable.

Since the presidential campaign kicked off last year, the filter bubble has been the subject of fierce discussion, credited with (or blamed for) everything from the surprise of Donald Trump's victory to the proliferation of fake news to the eroding of democracy.
