Both. Depends on whether or not they can smell you. Usually pre-dawn I am moving up hill towards my hunting spot (because thermals are flowing down hill during the night), and encountering bears at that time they usually can't smell me. so sometimes they get huffy, but after I announce I am a person they leave. If the bear can smell me they always run off, because we hunt them too. I've been inside 10 yards from dozens and dozens and dozens of bear (without bait) and have not yet been injured, even though some of the bears take more convincing to leave than others, and some of those times have been with sows and cubs. However, I know 2 people, personally, who have been attacked by black bears. So it's rare but can happen. Carry bear spray until you can read bear body language and have the confidence to interact with bears without protection. Most people that are scared of bears just haven't ever spent much time with them and it's more a fear of the unknown. That doesn't mean I'm careless around them though.
