triple checking
I'm thankful for threads like this, even though I lament the man's injury that led to it.
First, thanks again to Pax for reminding us of those 4 rules. (I've bookmarked this thread in 3 of my bookmark folders for frequent review: shotguns, rifles & pistols.)
Second, I want to offer a comment about fallability of human consciousness and a story about the importance of "triple checking" when it comes to activities that can lead to death.
Somewhere between Rene Descartes & Albert Einstein, humans in the western world came to believe that we are "machines". This is due in large part to a pervasive view that philosophers of science call "the mechanistic perspective": the world and everything in it are machines ("mechanisms").
As a biologist who has taught anatomy & physiology, I can attest to the large number of references in modern biology textbooks to "mechanisms" in our body: hearts are viewed as pumps; blood vessels as pipes; kidneys as filters; bones as levers, brains as computers, etc.
The view is egregiously incorrect. Neither we nor any other living thing is a machine. Living beings lack the precision of machines that can be precisely programmed to do a repetitive task over and over and over again without fail.
Human cognition, including perception, is fallable. That's why crimes are hard to convict based on eye witness accounts alone.
Rock climbers (I'm one, even though never got past novice stage) do a routine when rappeling: check the knot, double check the knot, then have your partner check your knot. You only get to make one mistake when rappeling.
Here's a story that I recently posted in another thread (pirates and guns) a couple of weeks ago that relates to my obsession with triple checking.
A few years ago, I walked into the Eddyline kayak store in Anacortes, WA to pick up my new kayak. I was greeted by somber faces all around.
When I asked why everyone was so somber, they told me that morning a man had been found in the harbor upside down in his kayak, drowned. Seems he was a novice, and when he put the tight-fitting neoprene spray skirt on the cockpit, he forgot to leave the pull strap out. He also had no knife to cut himself out.
He flipped over, couldn't get the neoprene skirt off, couldn't eskimo roll, and couldn't cut himself out.
All the way home (6 hour drive), with my kayak on my truck, I thought about the way he died, imagining the horror of what his last minutes must have been like.
Since then, I've always triple checked:
Pull strap out? Check.
Pull strap out? Check.
Pull strap out? Check.
Now, I do the same thing with my guns.
