Mathematical modelling of the anchoring effect on the underconfidence bias / Modelado matemático del efecto del anclaje sobre el sesgo de subconfianza

Macbeth, Guillermo, Razumiejczyk, Eugenia 25 September 2017 (has links)
The anchoring effect is defined as the tendency of human thought to the fixation on certain pieces of information that affect decision-making. In the same context, the underconfidence bias is understood as an agent’s propensity to underestimate his or her own objective performance. While some aspects of these phenomena are well known, there are no formal models that specifically describe the relationship between both. This paper presents: i) an experiment that illustrates the anchoring effect on the underconfidence bias by both reducing and amplifying such bias in the domain of geographic decision tasks and ii) the foundations of a new mathematical model that promotes precision in the study of the relationship between anchoring and underconfidence. / Se define el efecto de anclaje como la tendencia del pensamiento humano a la fijación endeterminados fragmentos de información que afectan la toma de decisiones. El sesgo de subconfianza, por su parte, se entiende como la propensión de un agente a subestimar su desempeño objetivo. Si bien se conocen algunos aspectos de la interacción entre ambos efectos, no se dispone de modelos formales que describan tal relación específica. Este estudio presenta: i) un experimento que pone en evidencia el efecto que ejerce el anclaje tanto para reducir, como para amplificar la subconfianza en tareas de decisión geográfica y ii) los fundamentos de un modelo matemático novedoso que permite estudiar con mayor precisión la relación del anclaje con la subconfianza
