Abstract

Since the outbreak of the new coronavirus, the assessment of the validity of information has become important from the national to the individual level. Belief bias is one of the cognitive biases that make them deviate from what is rational. In previous studies, it has been confirmed mainly by syllogism, but there is a big difference between syllogism and the information that people actually evaluate, and this difference may cause a difference in the individual tendency of belief bias. Therefore, in this study, we created a text task that is similar information people evaluate in real life, in order to examine whether there is a difference in the tendency toward belief bias. The results showed that there was no relationship between the tendency toward belief bias in syllogism and the text task, suggesting that the mechanism of belief bias in each task is different. Next, in order to explore the mechanism of belief bias in the written task, I developed a model that assumes that people evaluate the probability that the information in the text is correct, and make a judgment about its validity. The model predicted about 50% of the belief bias.
