I could be thinking of a different breed, but I always thought black bears, especially females, might behave differently than brown or grizzly bears with respect to the lay down and play dead tactic. I didn't think the same strategy worked for both and one may need to grab a weapon and fight back if you see the bear saying grace while you are playing dead. :)[/quote]
The two bear types do in many cases behave differently. However, a female black or grizzly will understandable in maternal cases with their young react exactly the same; naturally so. But black bears tend to be much more proprietorial, creatures of opportunity and thus a little less predictable, imo, in their aims.
Playing dead however needs to be weighed against many factors and it is not necessarily a good choice. The problem is that being surprised, as is much often the case, there are only seconds to react. If the action of the bear is predatory, often in black bears especially, then playing dead may not be wise whatsoever, in fact, fighting with everything you have available might be the only thing that helps. On the other hand, a 600 lbs grizzly may charge at 30 km/hour directly at you, only to stop, if you play it right, mere feet away, huffing, puffing and smacking the ground only to turn away and leave. In many cases it becomes a kind of test of wills and running excites food or threat instincts.
Although it is dangerous, if not deadly, to run from a bear, it is understandable. The flinch response and the fight or flight response usually requires training to overcome. FWIW, I think it's expecting a lot from occasional hikers to be able to overcome their reflex and panic responses, no matter how tragic the result.
Like you say it is understandable to flee and it is much to expect from occasional hikers, not understanding bear nature, to do the right thing - knowledge, as in all things protects.
Have mentioned this author before as he has worked in study near where I live and it is highly recommended to help with understanding bear natures in regards to encounters and other matters.
