Irrationality is cognition, thinking, talking or acting without inclusion of rationality. The term is used to describe thinking and actions that are, or appear to be, less useful or more illogical than other more rational alternatives.
Irrational behaviors of individuals include taking offense or becoming angry about a situation that has not yet occurred, expressing emotions exaggeratedly (such as crying hysterically), maintaining unrealistic expectations, engaging in irresponsible conduct such as problem intoxication, disorganization, or extravagance, and falling victim to confidence tricks.
The study of irrational behavior is of interest in fields such as psychology, cognitive science, economics, game theory, and evolutionary psychology, as well as of practical interest to the practitioners of advertising and propaganda.
Morality (from the Latin moralities "manner, character, proper behavior") is a sense of behavioral conduct that differentiates intentions, decisions, and actions between those that are good (or right) and bad (or wrong). A moral code is a system of morality (for example, according to a particular philosophy, religion, culture, etc.) and a moral is any one practice or teaching within a moral code. Immorality is the active opposition to morality, while amorality is a passive indifference toward morality.
