Editing Rationality (section)

=== Ideal and bounded ===
Various theories of rationality assume some form of ideal rationality, for example, by demanding that rational agents obey all the laws and implications of [[logic]]. This can include the requirement that if the agent believes a [[proposition]], they should also believe in everything that logically follows from this proposition. However, many theorists reject this form of logical omniscience as a requirement for rationality. They argue that, since the human mind is limited, rationality has to be defined accordingly to account for how actual finite humans possess some form of resource-limited rationality.<ref name="Harman2013"/><ref name="Knauff2021b"/><ref name="Moser2006"/>

According to the position of [[bounded rationality]], theories of rationality should take into account cognitive limitations, such as incomplete knowledge, imperfect memory, and limited capacities of computation and representation. An important research question in this field is about how cognitive agents use [[heuristic]]s rather than brute calculations to solve problems and make decisions. According to the [[satisficing]] heuristic, for example, agents usually stop their search for the best option once an option is found that meets their desired achievement level. In this regard, people often do not continue to search for the best possible option, even though this is what theories of ideal rationality commonly demand.<ref name="Knauff2021b"/><ref name="Moser2006"/><ref name="Bendor2009"/> Using heuristics can be highly rational as a way to adapt to the limitations of the human mind, especially in complex cases where these limitations make brute calculations impossible or very time- and resource-intensive.<ref name="Knauff2021b"/><ref name="Moser2006"/>
