How does a person, or is it even possible to, escape, transcend or conquer meta-ignorance?
Meta-ignorance being that state of mind made most recently "famous" by Don Rumsfeld in his refering to the (Bush) administration's "don't know what we don't know".
So - how does one acquire knowledge of something - deliberately! - if he isn't even aware of his lacking it. So - not knowing THAT you don't know AND not knowing WHAT you don't know are two slightly different questions.
I'm trying to address both. How does one "make sure" he knows what he needs (or wants!) to know?
This is along the lines of the "golden hammer" philosophy. If you don't tell someone there are other tools that can be used to solve problems, everything looks like a nail. The reason is because other tools haven't been demonstrated to be as useful as the "golden hammer".
Educated people do not manage administrations. If educated people did manage administrations, things would be approached empirically instead of just using a blanket application (golden hammer) for everything.
Of course the statement by Rumsfeld was pure political BS. They didn't not know anything, they refused to see the obvious. Not seeing was in the realm of Bush's handlers who told him what not to see. Politics are run by corruption rather than reason. Those who make a fortune profiteering control the "blinders" that administrations wear, and EVERY administration wears them. As is said "don't follow the nose follow the money".
