Many people are still unaware that certain social media sites, like Facebook use a complicated computer algorithm to control what appears in your news feed or home page. Basically, you see more of what you’re expected to like and less of what you aren’t. This is designed to encourage you to engage with and continue spending time on their platform and has obvious advantages for them. The more time you spend on their site or app, the more impressions their advertiser’s ads get and the more money the company makes. However, one of the most interesting and unanticipated effects these algorithms have had is what some are calling the “echo chamber.”
