The anchoring effect is a bias in the decisions and responses of people, caused by the involuntary interaction in thought systems 1 (Instinctive) and 2 (Rational) and activated by the way in which situations or questions are formulated. This bias leads to the generation of inconsistencies in predictions about the decision-making of individuals with respect to those expected from orthodox economic theory where individualism and rationality predominate in the search for equilibria that maximize the expected utility. This paper analyzes this effect through a survey of 810 people from the city of Bogota, in which 7 questions were answered, of which 5 were aimed at identifying the sociodemographic characteristics of the respondent to segment the sample, and 2 questions for the what anchoring effect. Initially the existence of the effect is verified and then the resistance and the same time that there are some groups of people, segmented by gender, university career, socioeconomic stratum, family education and ages, in order to determine the differences between each one of them. . . Finally conclude by proposing and analyzing how the anchoring effect can affect different types of activities according to sociodemographic characteristics.
