I disagree with you on academia, as the checks & balances plus the peer review system for worldwide recognised published research kill and destroy bullshitters. I am not saying there aren't any but having been in both academia & corporate, the latter is infested with them.

In startup world, they get also eliminated quite rapidly as they will just fail. Success of any startups is not to raise funds but to get customers who will pay for value and for that bullshitters cannot trick the system.
