I have a theory that people who find themselves running major-league companies are real organization-management types who focus on what they are doing this quarter or this annual budget. They are somewhat impatient, and focused on the present. Seeing these things requires more people with a historical perspective who are more thoughtful and more right-brained -- but we end up with an army of left-brained immediate doers.
So it's more or less guaranteed that every time we get an outlying, obscure event that has never happened before in history, they are always going to miss it. And the three or four-dozen-odd characters screaming about it are always going to be ignored.
If you look at the people who have been screaming about impending doom, and you added all of those several dozen people together, I don't suppose that collectively they could run a single firm without dragging it into bankruptcy in two weeks. They are just a different kind of person.
So we kept putting organization people -- people who can influence and persuade and cajole -- into top jobs that once-in-a-blue-moon take great creativity and historical insight. But they don't have those skills.

I want to emphasize how little I understand all of the intricate workings of the global financial system. I hope that someone else gets it, because I don't. And I have no idea, really, how this will work out. I certainly wish it hadn't happened. It is just so intricate that all I can conclude, by instinct and by reading the history books, is that it will be longer, harder and more than we expect.
This is a very good quote, but Grantham is being coy in his last paragraph. What he really means is something like this:
"I have been around long enough to know that nobody knows enough about financial markets to bet the ranch on any particular set of assumptions about market behavior. The only way to survive and prosper in the long run is to expect extreme events, and to use simple investment/trading models whose results don't vary a lot if your assumptions about the odds of such events turn out to be way off."
