"Arguments from authority carry little weight — “authorities” have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts."

That's the most controversial, because a lot of people want to be authorities and don't want to be questioned.

For instance, the origins of Covid... or really lots of things about the pandemic were pushed by authorities with little justification other than authority. It turns out many of those things were subsequently reversed or reasonably doubted.
