> Well, hard-working but not clever people will do useless work and create extra work overloading everyone else. BUT, this happens when they don't have good management and leadership above them, to prioritize and handle them bite-sized pieces, and to set their frame of mind to focus on "results in the bigger picture".

I've always thought of "stupid" as different from "not smart". I can't fault people for not having the experience or knowledge that I or others have. I tend to think more of an "active stupid" as a lack of common sense, and making actually poor choices as opposed not making good ones.

To me, it's more the difference of "My laptop is overheating and I can't figure out why" versus "My laptop is overheating so I poured water on it to cool it off."
