I've been meaning to ask this for a while now: Is there evidence that human cognition consists mostly of cached lookups, or is this just theorizing? Google reveals that the term "cached thoughts" originated here; I've been perusing some of the literature on pattern recognition, but most of those studies examine how we pattern-match faces, objects and letters rather than thoughts. I've yet to see any study or paper that directly supports Eliezer's claims in this post, which makes me a bit suspicious.
