Spot on, in every interview I ask the hiring manager if they have ever jumped out of a plane, and if they say "no" my respect for them drops to zero (sorry, it's a fundamental subconscious response I can't help it). I call their boss, tell them that their subordinate forgot to self-actualize, and I get made their manager on the spot. It's how I got my last two jobs.
I have seriously thought of operating a horse camp for executives. Most of what's out there is touchy feely healing lodge crap, where historically, cavalry was where leaders were minted, and their core training was sometimes as short as a few weeks.
People in offices spend most of their time around unstable neurotic personalities, and it means they have no gravitas to bring to their teams. That instability breaks creative flow and prevents people from committing, and that dissonance is what creates stress and suffering that staff take home.
It's no accident that one the most famous charisma trainers, Olivia Fox-Cabane, was/is also a horsewoman as well.
It's funny to say remedial horse camp for crap execs, but if you have ever been on one of those infantalizing management retreats, treating people like adults would be orders of magnitude better.
