For black bears, foregoing a fight is their default setting, even when cubs are involved. You almost have to try to get mauled by one.

I’ve ran into plenty while hiking, even with cubs, and the second they realize I exist, they haul ass in the opposite direction.

That being said, if one doesn’t run away when you make a lot of noise and wave your arms around, exercise caution because it might be acclimated to humans or starving.
