Decision-making is a special process of human activity aimed at choosing the best possible action. Both in the life of an individual and in the daily activities of organizations or society as a whole, decision-making is the most important component that determines their future. Yielding to the computer in the speed and accuracy of calculations, a person has a unique ability to quickly assess the situation, highlight the main thing and discard the secondary, measure conflicting estimates, fill in the uncertainty with his guesses. At the same time, the number of erroneous decisions is large, and the strength and depth of their negative impact is growing along with the power of human society.
