Economics[edit]
Individuals or organizations are called rational if they make optimal decisions in pursuit of their goals. It is in these terms that one speaks, for example, of a rational allocation of resources, or of a rational corporate strategy. For such "rationality", the decision maker's goals are taken as part of the model, and not made subject to criticism, ethical or otherwise.

Artificial Intelligence[edit]
Within artificial intelligence, a rational agent is one that maximizes its expected utility, given its current knowledge. Utility is the usefulness of the consequences of its actions.
