1) Proving yourself in a technical field gives me a better feeling about your perspicacity of another technical field (counter-example: Richard Feynman) than someone who hasn't. Mr. Gates has this background, Ms. McCarthy doesn't. Not a guarantee, but a first-order filter.
2) Your statement when you could just do your own review of the data negates your premise, unless you think parent is an MD.
