'Shep' although I can understand to some degree yr angst about this subject as I'm from the old school where CRM & ALAR etc where words that where being dreamed up by some uni boffins but Threat & Error management have a very real place in today's work place not just aviation.
A slippery floor at a supermarket is a threat, you don't need to have a gun held to yr head to be threatened.
High terrain around an aerodrome is a threat as well as fatigue despite both pilots knowing the area well & feel they had adequate rest the previous night.
That terrain will always be there, you can't change it you may think you know it well enough not to even consider it anymore but it only takes a slight distraction & bingo that terrain is now a huge threat hence bringing it to ones mind just as a top-up prior to decent could very well mitigate a threat not even thought of.
There's been plenty of cases where the pilots who where well versed with the AD & it's surroundings flew a perfectly serviceable plane into terrain.
Everything we do in our lives could be considered a threat,a risk so to speak and like in aviation where the risks are calculated, learned & assessed the same goes for you simply getting in yr car to drive to work although the latter we take for granted & see the results nightly on the news!.
CRM which is all part of ALAR/threats etc to me means I am not alone up there whilst flying & there are many things to consider where once upon a time I would never have considered half the stuff I do these days of any consequence.
It's about being educated, right or wrong we live & work in a very different world these days where work pressures,time scheds & family life is fast & forever changing:-).
Stay safe out there guys/gals, the bogey man is ever present!
