“Arguing in good faith means being willing to consider the possibility that we are wrong and that the person we are arguing with is right. It means constantly monitoring and trying to control for our own biases. And it means being willing to revise our positions once we realize that we can no longer defend them. This doesn't require self-doubt or indecision. But it does require humility and enough respect for reality to understand that we really will be wrong from time to time. Once we admit this, we should also be able to see that always acknowledging the possibility that we might be wrong is the only way to make sure that we are always at least right about something.”
