And such experts are routinely denounced by people who know little about the subject in question. I leave examples as an exercise for the reader.
True, but that seems inconsistent with taking human experts but not algorithms as authorities. Maybe these tend to be different people, or they're just inconsistent about judging human experts.
Presentation will influence how people receive your ideas no matter what. If you present good ideas badly, you'll bias people away from the truth just as much as if you presented bad ideas cleverly.
I'm not sure that explains why they judge the algorithm's mistakes more harshly even after seeing the algorithm perform better. If you hadn't seen the algorithm perform and didn't know it had been rigorously tested, you could justify being skeptical about how it works, but seeing its performance should answer that. Besides, a human's "expert judgment" on a subject you know little about is just as much of a black box.
I'm really late here, but a few problems:
