Ideología y razonamiento: un estudio sobre el sesgo a mi favor.

Myside bias has been characterized as the tendency for people to produce and evaluate arguments in a manner biased towards their ideology. The main objective of this paper is to analyze myside bias in an argument evaluation task. We constructed a test composed of two parts: a Likert-style questionnaire about personal attitudes and an argument evaluation task. Two controversial topics were employed for constructing this reasoning test namely, legalizing abortion and lowering the minimum age of criminal responsibility. Participants (N=247) were recruited from a secondary school and two universities in Córdoba, Argentina. We found a significant correlation between opinions regarding legalizing abortion and the assessment of arguments about abortion. However, we found a weak correlation between the Likert-score obtained regarding the age of criminal responsibility and the argument evaluation task towards that topic. Besides, we analyze the relation among myside bias and two variables of interest: educational level and formal instruction in logic. Regarding educational level, we haven't found a significant difference between the results obtained by secondary students participants and by university students participants. Regarding formal instruction in logic, we found that myside bias diminishes among participants with more training in logic. [ABSTRACT FROM AUTHOR]
