Not Knowing What One Doesn't Know

"Foolish people understand quickly, or believe they do, because they are not capable of imagining the difficulties and hence have no hurdles to leap over." -George Sarton

The above quote from the 1950s lines up with a named cognitive bias from late 1990s known as the Dunning-Kruger effect, the idea that unskilled people have no (or limited) capacity to realize the level of their own inadequacies.

Taken together, it seems fitting that a major goal of any society should be to instill the idea that we should never assume we're done learning.
