What is the myside bias?

The myside bias is defined as the tendency to favor one's own beliefs or conclusions while ignoring or undervaluing evidence that contradicts those views. This cognitive bias is prevalent in situations where individuals are asked to evaluate arguments or information related to their pre-existing opinions. It leads to a skewed assessment of evidence, often resulting in distorted reasoning where individuals systematically prefer information that supports their stance while dismissing information that challenges it. This phenomenon can severely hinder objective decision-making and understanding, as it causes an imbalance in how information is processed, often reinforcing misconceptions and perpetuating polarized views.

The other options do not accurately capture the essence of myside bias; for instance, considering alternative views and weighing evidence impartially reflects an open-minded approach rather than a bias. Additionally, a method of investigating unbiased opinions does not relate to the inherent tendency of bias as exhibited in myside bias.
