How Your Brain Figures Out What It Doesn't Know
hex0D passes along an article at NPR about a study that examined the biology behind the self-assessment of knowledge. Quoting:
"We isolated a region of the prefrontal cortex, which is right at the front of the brain and is thought to be involved in high-level thought, conscious planning, monitoring of our ongoing brain activity,' Fleming says. In people who were good at assessing their own level of certainty, that region had more gray matter and more connections to other parts of the brain, according to the study Fleming and his colleagues published in the journal Science."
In The Science of Fear (a book I heartily recommend), Daniel Gardner claims the strength of our "feeling of knowing" generally has no statistically significant correlation with factual reality. Humans are not very good at "knowing." and our most cherished concepts of "truth" may be unverifiable or demonstrably false.
Which is why, paradox intended, a person who knows he knows nothing is wise.
"In March 2003, Donald Rumsfeld engaged in a little bit of amateur philosophising: "There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know." What he forgot to add was the crucial fourth term: the "unknown knowns", things we don't know that we know - which is precisely the Freudian unconscious. If Rumsfeld thought that the main dangers in the confrontation with Iraq were the "unknown unknowns", the threats from Saddam we did not even suspect, the Abu Ghraib scandal shows where the main dangers actually are in the "unknown knowns", the disavowed beliefs, suppositions and obscene practices we pretend not to know about, even though they form the background of our public values. To unearth these "unknown knowns" is the task of an intellectual."
