User:Aaron Schulz/Irrational

Five definitions for the ambiguous word "irrational":
 * An action that does not logically follow from one's values
 * An action for which the justification was not a serious attempt to logically follow from one's values
 * An action that does not logically follow from one's own (egoistic) interests
 * An action for which the justification was not a serious attempt to logically follow from one's own (egoistic) interests
 * An action which was not thought out, e.g., largely emotional, chaotic, or somewhat random.

The above can be split into more definitions by resolving what is meant be "logically". Does it mean "formally", "probabilistically", "reasonably", or something else? Do heuristics that work well but can't be well explained by the actor count (this is very much how people think in practice)?
