Calculation of the social laziness syndrome level indicators in the game of top-level sport teams

The aim of the study was to calculate instrumentally available indicators of reducing the level of results of highly professional top-level teams in football (1,458 matches), hockey (1,551 matches) and basketball (274 matches) in 2016-18 due to social laziness syndrome. Using the method of determining the rating of the team from the previous results the difference in the ratings of two participants in the upcoming match and the proportion of actually won victories was compared. Comparing the proportion of matches won with the advantage in the ranking it was found that the dynamics of compliance of these indicators begins to distort considerably with a significant advantage of one of the teams. In contrast to other works where the amount of social laziness could not be established experimentally, in the present work it is found that a team cannot expect more than 85% of the winning probability even with a huge advantage over an opponent. The effect of social laziness syndrome is quantified. It indicates itself in the games of unequal teams and allows a weaker team to gain an additional 10-17% of the won matches of professional teams of the top level.
