If you look at things that are actually hard, nobody keeps you from getting the info. You're just not going to understand that graduate seminar in ergodic theory, though you're welcome to attend.
The reason they keep you from the info is of course you'll see the naked emperor.
Science is "easy" because we can model it, to a degree.
Non-science is so hard that we can't even model it, it's that complicated. So instead we try to voodoo our way around it, rely on simple heuristics, history, etc.
But the man who invented 1-800-GOT-JUNK and plastered the phone number on the side of every one of his bins was not some better of Richard Feynman. He understood one thing really well: If you solve a problem, have simple messaging, and unabashedly self-promote you will win.
The lawyers, and accountants, and technologists, will all come and help you with the complicated stuff in exchange for a piece of that mountain of cash.
I think one has to differentiate between "complex" and "complicated". Complex stuff requires Big Brains. Business is not complex, all its processes are simple and fairly well-understood; but it is complicated by the interaction of so many factors.
If you have ever been in a relationship, you know how irrational people are: ergo, ability in logic and mathematics plays little role.
Went to MIT in engineering/science, and I would do a mental face-palm when I heard other engineers try to ‘sell’ what they are working on.
It’s the “curse of knowledge” where you forget how to relay ideas because you forget your axioms have been updated but the person you are talking with has not had theirs updated.
This is to say some people (in all fields) can sell ideas, and some can’t. Just as some can do high level mathematics, and some can’t. Those curves overlap in unexpected ways.
This goes a little further beyond this point I was making, but I also see collective decision making like this as being more fair. Everyone at the buisness is affected by these decisions, so everyone should share in the decision making process. Natural leaders and experts should become apparent and people will listen to them if they don't attempt to bludgeon them with their credentials.
And what kind of "high level physics" do engineers know? A typical masters track doesn't cover the hard maths like in GR, sounds more arrogant than anything... kind of proving my point ;)
That said, I do always try to bring along "business people" in engineering challenges and considerations, for which you don't need a full engineering degree. I do appreciate when I get the same treatment.
