I've met several MBA's, and they are more 'partially literate' in that they can write huge quantities of stuff, but each paragraph has nothing to do with the last paragraph.

Similarly, they can read whole books very quickly, but they do so by reading just the first sentence on every page. This is what gives them the superpower of reading large technical emails, and responding to them in seconds about a completely unrelated topic.

The most highly educated person in my extended family has the worst spelling and grammar of anyone I've ever seen. Getting a hand written note from them is always a guessing game.

God, this annoys the crap out of me. People say I write novels in my emails, so I tried breaking things up once for an MBA. It resulted in a dozen or so emails that when concatenated would equal the "novel" they'd have originally complained about.

Lesson learned: MBA's seem to value incomplete communication, and email headers over a condensed explanation of what's actually relevant.

That's how you know they are real.
