Abstract

In this work, no denying the role, or even more so, the value of rational thinking, it is assumed that it is not the only effective tool for man to achieve his valuable goals. It is conjectured here that sometimes irrational thinking is an equally good (and sometimes even better than rational thinking) means of achieving them. In the light of these assumptions, the goal of my work is to indicate the benefits that may be the result of irrational thinking in the colloquial (i.e. unscientific) domain of everyday human practice. The given examples of irrational thinking come from research in the field of cognitive and social psychology and behavioural economics. Their results prove that irrational behaviours (including thinking) are neither accidental nor senseless, and on the contrary systematic and easy to predict, they constitute important arguments for considering the phenomenon of irrational thinking. I also discuss this issue although only to a limited extent.
