RESUMO:

Several studies have addressed the evidences of behavioral biases regarding individual’s decisions either in an isolated or in a group composition. However, there are not reports in the academy about researches that seek to observe how the consciousness impact about the bias or knowledge regarding biases by individuals in the reduction of its impacts. In this way, the current research has its main objective focused on the investigation of the decreasing impact of information regarding behavioral biases related to the decisions taken by individuals. In other words, this research seeks to answer how the conscious or knowledge about de biases act concerning their decisions. It is a descriptive, quantitative research developed from a quasi-experiment done through a survey. The samples are of non-probabilistic types, composed by participants of an extension course in finance (210 valid observations), and another one by the accounting students of UFRN (288 valid observations). The quasi-experiment was implemented from an execution plan that sought to determine the evidence and intensity of the behavioral biases in two distinctive moments, before and after, the exposition of the videos that explained and promoted the consciousness and objective information to the individuals about the different behavioral biases. The cross-tab technique was used having as a significant statistical verifier the McNemar test, bearing in mind that it would be the most adequated test for studies that involve “before and after”. The results have shown a significant reduction on the impact of the loss aversion and mental accounting and marginally for the anchoring biases. However, it was not possible to notice a significant change according to the statistical point of view regarding the endowment effect. Therefore, the current research presents retraction evidence about the impact on behavioral biases from the moment that the individuals have become conscious regarding the biases. To the verify the persistence of this impact over time, a new intervention was made a few months after, seeking to check the possibility of the impact being only transitory. For this sample, the impact does not seem to persist over time. However, that does not mischaracterize the main idea of the research, neither the knowledge as a dampening of the behavioral biases, considering that the intervention done was extremely short and raised significant impact, that could provoke insights for future researches with the use of long-term methodologies as for example, semester courses.
