Without new experiences we are left alone with our ideas, which themselves can be exploited. The algorithms have learned that exposure to different ideas can fuel a moral outrage that keeps us clicking, engaging, and posting. Nuance or concreteness aren’t profitable. Facts are elided and extreme versions of different ideas are presented to us to ensure that we remain emotionally engaged with a particular platform or community. Those responsible will argue that this is not the intent, but intention is not really the issue. The algorithm tests and tests and tests and finds approaches that work.
