  • Irrationality is cognition, thinking, talking or acting without inclusion of rationality.
  • The term is used, usually pejoratively, to describe thinking and actions that are, or appear to be, less useful or illogical than other more rational alternatives.

      Irrationality is doing something without rationality, without reason or any logic behind it.
  • people fail to realize the irrationality of their actions and believe they are acting perfectly rational, possibly due to flaws in their reasoning

      This is impoetant because it is a valid reason for irrationality and also a reason for people being idiots.

      I thinl this is very important bacause it is a big reason why peopl are stupid/irrational.
  • Irrational is not always viewed as a negative. The Dada and Surrealist art movements, for example, embraced irrationality as a means to "reject reason and logic". Andre Breton, for example, argued for a rejection of pure logic and reason which are seen as responsible for many contemporary social problems [1].

      Being irrational is not always bad, its just when it is the wroung reason for irrationality, sometime you need irrationality, it could help you think a little differenter.
  • Irrationalist is a wide term. It may be applied to mean one without rationality, for their beliefs or ideas. Or, more precisely, it may mean someone who rejects some aspect of rationalism, variously defined. For example religious faith may be seen as, in part, a rejection of complete rationalism about the world; this would be contested by some religious thinkers, in that the rational is a debatable term. On the other hand, it might be considered irrationalist to buy a lottery ticket, on the basis that the expected value is negative.

      This paragraph is important because it touches a little more on irrationality, like the example they give.
  • 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. People with a mental illness like schizophrenia may exhibit irrational paranoia.

      I wonder if irrationality is really related to a mental disorder.
  • The term irrational is often used in psychotherapy and the concept of irrationality is especially known in Rational Emotive Behavior Therapy originated and developed by American psychologist Albert Ellis. In this approach, the term irrational is used in a slightly different way than in general. Here irrationality is defined as the tendency and leaning that humans have to act, emote and think in ways that are inflexible, unrealistic, absolutist and most importantly self- and social-defeating and destructive[1].

      I think this is important because it shows how irrationality is used for psycotherapy
  • Irrational thought was seen in Europe as part of the reaction against Continental rationalism. For example Hamann is sometimes classified as an irrationalist.
  • In psychology, excessive rationality without creativity may be viewed as a form of self-control and protection
