There's the filter bubble of the internet, in which we willingly surround ourselves only with information sources with which we agree, soon coming to the conclusion that everyone agrees with us.
The other kind is the filter we can choose to build to avoid falling into a rabbit hole of wasted time, misogyny and dissatisfaction. This is to avoid the endless clicking, the hateful comments, the mind-numbing noise of the net.
Here's a hint: The first kind of filter is easy to build and satisfying in the short run. It's reassuring to believe we're right.
The second kind, the one that builds a foundation for us to do better work, is always under attack from within and without, and it's tempting to stop using it. Tempting to give up, but ultimately worth the effort.
The easier the filter is to build, the less it's worth.
