"Some methods and strategies developed in the field of behavioral economics have created problems with replication or did not result in success when used in uncontrolled conditions, e.g. in medicine, where attempts to encourage patients by doctors with specific impulses to follow the recommendations ended in failure .. Perhaps this is related to the inappropriate choice of methodology of science, especially in areas such as social psychology, as indicated by the work of economic behaviorists, including Daniel Kahneman, who responded to the replication crisis in 2014 , referring to the less strict methodological standards applied to researchers conducting replication.. He also criticizes the lack of contact between the replicators and the authors of the original research.. In addition, he points out that elements considered insignificant (such as font and word selection) have a significant impact on the behavior of people, including scientists themselves.. Influences of non-substantive aspects of work in a highly rational environment are important, especially with the assumption that pure rationality of science is a myth.. With this caveat, I will discuss the concept of systemic irrationalism and then the selected heuristics described by Science is a highly rationalized system of cooperation between people."
