Social media algorithms are designed to show us more of what we already believe. It's dangerous to be surrounded by too much homogeneity.
We are each irrational in our own way and carry bias. It's easy to live in a bubble of our own assumptions and judgments. Diverse opinions and ways of thinking can help to ensure that we're open to other ways of thinking. It can also challenge us to have to stand up for what we really believe and test if it's in our core or something we're trying on at the time.
