I'm sorry you view the concept of expertise that way, but hey that's your own problem.
I guess you'd let me command your army unit then right? Because hey expertise is really just a presumption by the experts.
I expected someone to say that. This was actually one of the things I found most frustrating about bad military leaders. Of course, there is a culture known as JFDI (Just Flaming Do It), because in battle what matters is usually that
something is done decisively, rather than that the plan that we implement is necessarily perfect - it's usually much better to shout 'follow me!' and run forwards than it is to spend a few minutes static under fire working out exactly what to do.
What irritated me was when that attitude spread where it wasn't necessary. You could be out on the hills doing a bit of walking as adventure training, and the corporal would come up with a route, and brief his section. If one of the privates put up his hand and said 'excuse me Corporal, but wouldn't [this minor variation] make the route easier?', he'd usually be told 'pipe down lad, I'm in charge here' - in quite a few cases, he'd have been right, and sometimes everyone would have a miserable time because the commander's plan was actually quite stupid. Yes, the corporal will usually be right more often than the private - that's why he's a corporal - but it's stupid to expect him to be infallible, and counterproductive to make everyone act as if he is when it's not necessary. It gets much worse when you replace the corporal of five years' service and a couple of operational tours with a second lieutenant of two weeks', who dismisses the suggestions of his much more experienced juniors because he feels that listening to them would weaken his authority. Tell me that never happens at a political meeting!
It says something that JFDI disappears in the planning stage among special forces - absolutely anyone can chip in, and if they come up with something stupid then everyone else is wise enough to see that it's stupid, but they're also not afraid to take it on if it's actually useful. I liked that culture, and tried to make it work in regular work as much as possible - when I gave briefings to small groups of NCOs and/or officers, I usually ended them with 'any questions or suggestions?' Every now and again, someone with far less training and experience pointed out something I hadn't thought about.
EDIT: More to the point, why should a political community be run along the same lines as a military unit? I respect the RSM's right to come into his soldiers' rooms, inspect them and occasionally throw things out of the window, but wouldn't advocate for the police to start carrying out room inspections!
SECOND EDIT: I recognise that this is supposed to be a Q&A thread, so am happy if you'd rather stop the conversation.
