It’s easy to get trapped in your own echo chambers, to surround yourself with people who think like you do and to watch news media that reflect your belief system. But when we do that, we limit our ability to think for ourselves. Instead, we are at the mercy of social media algorithms, a circle of friends, and others who reinforce a tight control over what you can think and believe. You can find yourself swept up into a belief system that you may not truly want to belong in, but without learning to question it, you will never know for sure.
