Of course experts can be wrong, but you won't know that they wrong or how in any particular instance, so you won't be justified in agreeing on something contrary and silencing dissenters who bring up the expert opinion. I'm just talking about obvious reasonable behavior here. For instance, experts probably agree that nuclear radiation causes cancer. It would not be sensible to believe that nuclear radiation doesn't cause cancer and then expose people to that radiation, believing it's harmless just because experts are at risk of being corrupted.
