It’s one thing to be skeptical of a consensus, it’s another to go against it. When it comes to subjects outside your expertise, it’s best to go with the consensus, most of the time. It’s possible to support something and question it at the same time.

Skepticism is necessary for good decision making, but it needs to be healthy skepticism. Healthy skepticism not only involves questioning the assertions of others, but also ruthless honesty with yourself.
