Hindsight is 20/20 though, people may not realize that the people handling important things aren’t actual experts until the bottom falls out of whatever function the purported expert was managing.
In such a position I would slightly prefer to say “I should have hired an expert” and not “I was not keen enough to know that the person I hired was not actually an expert”
