When Henry Kissinger was first made head of the US National Security Council, Daniel Ellsberg of RAND Corporation was briefing him on options for Vietnam, and chose to add these words of advice:
You've been a consultant for a long time, and you've dealt a great deal with top secret information. But you are about to receive a whole slew of special clearances, maybe 15 or 20, that are higher than top secret...Scarcely 2 years later, Kissinger, in a meeting with Ellsberg, dismissed the group resignation of a team of consultants in Cambodia in protest of the policy of escalation because "They never had the clearances." Yet the consultants turn out to be correct. Kissinger's course of action was a failure.
First, you'll feel exhilarated by some of this new information... you will forget there was ever a time that you didn't have it, and you'll be aware of the fact that you have it now and most others don't... and that all these other people are fools.
Over a longer period of time... you'll eventually become aware of the limitations of this information... In the meantime, it will become difficult for you to learn from anybody who doesn't have these clearances. Because you'll be thinking as you listen to him, "What would this man be telling me if he knew what I know?" And that mental exercise is so torturous that... you'll give it up and just stop listening...
The danger is that you'll become something like a moron. You'll become incapable of learning from most people in the world, no matter how much experience they may have in their particular areas that may be much greater than yours.
Maybe it's time to change out the morons in charge.
