Degrees of ultracrepidarianism
The shoemaker may well be able to recognise 'good or poor workmanship' in other contexts, and 'the scientist' will (or should) have a wider scientific knowledge/know where to look up relevant scientific information, in both cases in a manner in which the 'person in the street' may not.

All I know is that I know nothing
The following quotes consist of individuals recognizing the limits of their knowledge. Viewer discretion is advised.

All men have to take most of their opinions upon authority–that is, to believe because others believe; and the reason is often a very good one. [...] In that sense I take my astronomy and nearly all my mathematics upon authority, as well as my belief in Rome or in Julius Caesar. I have not personally investigated the arguments in one case, or the evidence for facts in the other. My name is Rob Hafernik and I'm not an archeologist, I only play one on the Internet. Since I don't have any training in archeology, I'll be careful to document anything I say that relates to archeology back to some expert on the subject or clearly mark it as my own non-expert opinion. I do, however, have a BS degree in Aerospace Engineering (Texas A&M;, 1979) and worked as a government contractor for NASA on the Space Shuttle for three years. So, I'll express my professional opinion to matters relating to orbital dynamics, spaceships and so on.

As regards science, especially biology and physiology, I am not competent to criticize his interpretations. But as regards mathematics, he has deliberately preferred traditional errors in interpretation to the more modern views which have prevailed among mathematicians for the last eighty years. Their famous correspondence is said, by a learned German named Schmeidler, to have been entirely composed by Abélard as a literary fiction. I am not competent to judge as to the correctness of this theory, but nothing in Abélard's character makes it impossible. --Кřěĵ (ṫåɬк) 13:07, 3 June 2019 (UTC)
