 Something like this does capture the way we justify deferring to expert opinions of scientists or to the advice of doctors who know better than we do. Were we to try to second-guess them we could not profit from their expertise. To accept them as authoritative therefore requires deferring to their judgement, and allowing that to displace our own assessment of what is to be done. This is not blind deference: the subject remains attentive to higher-order considerations that determine whether the authority is trustworthy, acting in good faith, and so on. And the deference may be limited in scope and subject to checks of its effectiveness over time.
