People who get involved in things they do not understand, get their asses kicked, and blame other people are, by definition, idiots. Anyone who invested in Enron without taking the time to read an annual report (which made it startlingly clear that the business plan was "play a shell game") should have been diversifying in mutual funds and protecting themselves from their ignorance, not buying high-flying stocks directly.
You see, in the real world, when people take actions, those actions have consequences. When people make decisions out of ignorance, those consequences are frequently bad. "Genius" isn't knowing everything, it's knowing what you're a total !@#$ing dumbass about.
For example, you'd be a genius if you understood that these people and I have traded posts for years, and they understand my glib remarks. Instead, you don't know that you're a total !@#$ing dumbass about the established social interaction of long-time posters...which makes you an idiot.
