The article discusses the controversies surrounding football's video assistant referee (VAR) system, which was introduced to reduce refereeing errors but has instead created new uncertainties and challenges in understanding fundamental rules like offside and handball. The author explores the broader implications of VAR, highlighting the limits of rationality in various aspects of life beyond football. The article suggests potential solutions to improve the accuracy and efficiency of VAR decisions, such as implementing AI technology and creating new metrics like the Foul Probability Index. Ultimately, the debate over VAR reflects a larger societal shift towards data-driven decision-making and the ongoing quest for precision in measuring complex concepts. [Extracted from the article]
