Narratives, including narratives personally told to me, indicate clearly they have tactical excellence in their family/clan groups. That is indicative of a reasonable amount of intelligence.
Other narratives, indicate they are aware of what would happen if they began killing humans wholesale. We have narratives of past fights between these things and humans, and clearly, while BF has had some victories and has lots of nocturnally superior abilities, humans once they feel really threatened, will hunt an opponent almost to extinction - at least in their own backyard.
It may be a bit of genetic memory as well.
But for whatever reason, they elect to not embrace a general confrontational mindset - something that to me indicates a bit of prudent reasoning.
And THEN, with scores, and hundreds of endeavors to look for them and plant hundreds of trail cameras, they seem to be able to avoid the traps and drives of a supposed "superior mind."
In truth, most BF hunters have no idea what they're up against, much less how to succeed. And that's proven every day that passes.
