The author demonstrates that the bulk of futurological forecasts do not come true as well as predictions contained in scientific fiction. In his view the systematic mistakes of such forecasts are due not to the shortcomings of predictions, but to the fact that the development of civilization is unfolding in irrational direction. It is connected with the substitution of "paradigm of development" by the "paradigm of entertainment" - the distinguishing manifested process which has psychological roots. The author states that underestimation of the changes in human psychology is still alive and well in futurological forecasts what diminishes their exactness.
