I hope you are here because you know generally what a "filter bubble" is, and you want to do more than just being aware of the problem. You should want to pop your own personal filter bubbles. This page will get you started.
You might not always have the time, knowledge, or energy to engage critically with the algorithmically-run feeds in your life. In these times, turn them off. Don't use the feed when you are uncritical. Put the phone down. Close the laptop. Touch grass, or sit and stare at a wall. Commit to it. Don't use the device. Don't put it in charge. Do not touch it, if you are not prepared to be in charge.
"Turn it off" works at many levels; it covers a lot of what it means to be in charge of your device. Don't allow it to do more than you are wanting it to do
Everyone has to "turn it off" sometimes. You may not (yet) have the complete set of academic or technical skills to get online outside your bubble. Your available time and energy may be too small. In the end, "turn it off" is the common resting place for responsible geeks and laypeople alike. It can always be turned off.
It can always be turned off - but you don't always control the power switch. ... So learn to mistrust general human judgements about the world when coming from the filter-bubble-unsavvy.
