“Free and unencumbered dialogue is not optional either. We need to be able to discuss things so that others might tell us where we are stupid. And we’re all stupid. We might be stupid in our own peculiar ways, but nevertheless, we are all stupid. There is no such thing as an unbiased opinion, just like there is no such thing as a viewpoint without a blind spot. The best we can do is be aware of and try to counteract our biases and blind spots. But we can’t do it individually; we have to do it collectively, and more importantly: in a distributed fashion.”
