It's a social indicator, not a definitive attribute. I've known several MBAs personally and only one was legitimately intelligent -- the rest were sales guys who thought their MBA entitled them to make big decisions with perilously little background or knowledge of much of anything related to the situation. I know an MBA right now who is pursuing a business wherein he offers wifi hotspots to small businesses. His literature claims that renting one of his hotspots will make the business "PCI compliant". I've personally advised him on multiple occasions (gently at first, growing more stern over time) that this claim is patently ridiculous and only displays his incompetence to anyone knowledgeable in IT, but he refuses to amend his materials or statements. Just the tip of the iceberg with him. Granted these are anecdotes, but I think they embody the anti-MBA ethos. Qualified persons strongly dislike MBAs because MBAs often feel their MBA grants them immunity from doing things incorrectly, and that they are instantly authorities on everything without requiring any experience or research. I swear they have to explicitly teach that in business school, like: "Now, this degree grants you the magic power of never needing advice, information, or training, and you will always be right, and normal people won't understand that because they didn't go to business school... but remember, business school is the only school that matters. No one would have money without us! Just tell the nerds to shove it if they try to tell you anything else." It's far too universal a feeling among MBAs to be coincidental.
