It's self-propagating nonsense. In the immediate post-dotcom crash, I worked for a company that was run by a bunch of young HBS grads, who all had management consulting backgrounds, (and a few minor dotcom successes). They regarded themselves as geniuses. They couldn't make a decision on anything.

Their preferred working style was to not make decisions, and to hire consulting firms to make the decisions for them. So they hired these even younger consultants, who would work for a few weeks, and make their recommendations, and then those recommendations would not be put into action. No. Instead, more consultants were hired to review and then discard the work of the previous consultants. Rinse and repeat for a few cycles.

I cannot resist one story. The initial HBS/management consulting CEO was replaced by a new CEO, someone who had run one of the early search engine companies, and had a similar background. He turned out to be no better. What I found very entertaining about CEO2 was his business past. He was known for two decisions. 1) Declined to buy the very early Google for high six figures, when he had the chance. 2) Decided to buy Blue Mountain -- think Hallmark cards but online -- for $780M. Greeting cards. 3/4 of a billion dollars. 1000x the cost of Google at the time.

Yes, hindsight and all, but still. If I had made both decisions by flipping a coin, my expected value would far exceed what this business genius accomplished.
