It also made it possible for us to host online citizens’ assemblies so that we know those 10 people in the room are diverse, but they also have something connecting them, without again doxxing themselves. It enables the best of both worlds: We enable whistleblowing, epistemic injustice can be corrected this way, but you don’t get astroturfing or bots.
