A bear in the wild is not going to be a great target without bait and I most certainly would not be on the same level as the animal if I was armed with a bow. Remember, you still have to get home and if you've wounded a bear, even a small one, you have a big problem should you cross it going to home.
If you have bears using a trail on a regular basis, I'd hang a stand where a clear shot can be had WITHOUT leaving scent on the trail they use and I'd be hunting the low light periods during each day by entering the stand from a direction favorable to the wind.
If you live in an area that's well-populated, your scent will likely mean little to a bear as they acclimate to people's presence. And while bear have been dubbed as being half blind you best think twice about moving in the presence of a bear unless you are significantly higher up than said bear. But its noise that will spoil your chances faster than anything when all three senses are considered. A bear can hear a gnat pant and pinpoint its position from a half mile. I've watched bear at our deer feeders in the cabin yard sit up and stare at the woods fully two minutes before hearing a car on the road myself. I've watched a bear in the cabin yard watch with her ears as she follows another bear approaching the yard for a half hour before the other bear enters.
A bear will get used to your smell as long as you're not stinking up HIS trail. A bear might sit and watch you as long as you don't approach or make radically sudden moves but a bear hearing things not natural to its environment will be gone before you know it was there. There are exceptions to every "rule" and one of the cluster exceptions is if you startle a bear on a trail and it feels like there is no way out of the situation and all you have is a bow and a couple arrows, well, you might wish you had something that goes boom.
Baiting bear makes the hunting quite predictable. Winging it like you're suggesting put the odds way up in the bear's favor. You can increase YOUR odds by using the stand but if you think you can stalk or still hunt a bear you'd better do a lot of practicing.
