And yet qualified electricians make mistakes, take cheap routes, etc. leaving folks with unsafe houses all the time. Perhaps people would be better served not Appealing to Authority on that matter.As it happens, I know some pretty serious pure mathematicians.
They can tell me some things that I can (almost) make sense of. I believe them. It would be pointless for me to ask them to back up their reasoning - I wouldn't understand it.
This generalises across most fields of technical expertise.
The reason I believe the electrician who tells me that the wiring in my house is safe after inspecting it is because they're a qualified electrician. That's not fallacy, that's accepting the distribution of knowledge and expertise that is part and parcel of human society.
There's a reason why people who go to doctors get second and sometimes third opinions.
