May be something related to child resistant packaging. From the CPSC FAQ on the Poison Prevention Packaging ACT “For a package to be child-resistant, at least 85% of tested children must not be able to open the package during the first 5 minutes of the test”.https://www.cpsc.gov/FAQ/PPPA
There is considerable overlap between the intelligence of the smartest bears and the dumbest tourists (in reference to why the Yosemite garbage cans are difficult to use)
Worked in Yellowstone.
The bears are smarter than the majority of tourists.

Bears, only rarely, if ever, find themselves in trouble with natural features. And they can’t read the warning signs.
Design a camp ground so that people who don’t read the rules naturally fall in a pit that the rules warned about. Clear out the pit about sunset, and bus the pit folk to a motel.
Is that pit lined with mattresses so that those peeps will just isolate themselves for a day? I read the first sentence and nodded in approval: let the natural selection take the wheel but the second sentence made it much more humane.

How the hell they arrived at that number we may never know, but I’ll bet you it’s buried on page 4,987,253 in clause 6, subsection 8 of European Union Product Safety Report 156.421a. Or something.
85% of the time, it works every time
