I would definitely think this would be very topic-dependent.

Perhaps the flip side to this is to consider when (if ever) lies or mistruths are allowable. After all, a lie, believed sincerely, makes the believer 'wrong' about something. I can certainly think of things told to me by people I care about, that if they turned out to be lies, I wouldn't gain any utility or value from their revelation.
