Rationality is the quality of being guided by or based on reason.In this regard, a person acts rationally if they have a good reason for what they do, or a belief is rational if it is based on strong evidence.
It overlaps with psychology, philosophy, linguistics, cognitive science, artificial intelligence, logic, and probability theory. Psychological experiments on how humans and other animals reason have been carried out for over 100 years. An enduring question is whether or not people have the capacity to be rational.
Logic and rationality have each been taken as fundamental concepts in philosophy. They are not the same thing. Philosophical rationalism in its most extreme form is the doctrine that knowledge can ultimately be founded on pure reason, while logicism is the doctrine that mathematical concepts, among others, are reducible to pure logic.

choices made in such “hot” visceral states are not always rational, as dictated by economic theory. For example, David M. Cutler and colleagues (2003) investigate whether or not the increase in caloric intake over time could be seen as simply a rational response to the lowered
Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics. [1] Although the reality of most of these biases is confirmed by reproducible research, [2] [3] there are often controversies about how to classify these biases or how to ...
