Cached thought

From Lesswrongwiki

Jump to: navigation, search

A cached thought is an answer that was arrived at by recalling a previously-computed conclusion, rather than performing the reasoning from scratch. Cached thoughts can be useful in saving computational resources at the cost of some memory load, and also at the risk of maintaining a belief long past the point when evidence should force an update. In particular, cached thoughts can result in a lack of creative approaches to problem-solving, as cached solutions may interfere with the formation of novel ones. What is generally called common sense is more or less a collection of cached thoughts.
