No, not if the book is wrong obviously . In this interview case, however, you’d want to be pretty specific about where you thought those flaws might be and suggest ways to make it even better.

By “the book” I meant a well thought out process that follows the law, protects parties in a dispute, prevents retaliation, encourages reporting, and is well documented and understood. I’m probably missing a bunch of other best practices - not a certified HR Specialist.

My only aim here was to distinguish between disputes that arise in politically charged areas vs. the handling of those disputes which, I would argue should not be charged at all but rather an efficient run-through of a dispute process that “works”.

"The book" in this case starts with legal obligations under the Civil Rights Act, the Age Discrimination in Employment act, etc. A milquetoast 'well, I treat everyone equally' doesn't even come close.

How is treating people equally "not even close" to complying with those laws? I feel like I'm misreading to your comment, but it seems like treating people equally is exactly the point of those laws.

If a person is interviewing for a supervisory or HR position, there's a lot more involved than just their personal behavior, and even with personal behavior, just saying "I treat everyone equally" in a blandly shallow manner suggests a lack of experience with or thought about clashes of perspective in an organization.

Or, to use an analogy, consider interviewing someone who, when asked about their preferences and strategies for ensuring code quality, answers "I just write correct code in the first place". Even if they're correct in that statement, that's not the sort of person you want in charge of that subject, because most people don't work like that, even if they wish they could.
