algorithm radicalization

/ˈælɡərɪðəm ˌrædɪkəlaɪˈzeɪʃən/

Common

When recommendation algorithms push someone toward increasingly extreme content over time.

The mechanism is not ideological. The algorithm doesn't care about the content. It cares about watch time. Radicalization is a side effect of engagement optimization, not intent.
