"Cached Thought" wiki entry has been copied below for you connivance.
A cached thought is an answer that was arrived at by recalling the old conclusion, rather than performing the reasoning from scratch. Cached thoughts can result in the maintenance of a position when evidence should force an update. Cached thoughts can also result in a lack of creative approaches to problem-solving if one repeats the same cached thoughts rather than constructing a new approach.
What is generally called common sense is more or less a collection of cached thoughts.
The above entry focuses only on the negative sides of cached thought. Probably because it can be a large barrier to rationality. In order overcome this barrier, and/or help others overcome it, it is necessary to understand why "cached thoughts" have been historically valuable to our ancestors and in what fashions it is valuable today.
'''Cached thought''' also allow for complex problems to be handled with a relatively small number of simple components. These problem components when put together only approximate the actual problem, because they are slightly flawed '''cached thoughts.''' Valid conclusions can be reached more quickly with these slightly flawed cached thoughts then without. The aforementioned conclusions should be recheck without using '''cached thoughts''' if a high probability of correctness is necessary or if the '''cached thoughts''' are more then slightly flawed.
Is this an appropriate expansion of the wiki entry? The words are drawn from my observation of the world. How else should the above wiki entry be expanded?
