What Is Belief Bias In Behavioral Economics?

Belief bias is a phenomenon in which people’s evaluations or judgments of the truth or validity of an argument are influenced by their existing beliefs or biases. This can happen because people tend to be more receptive to arguments that support their existing beliefs, and may be less receptive to arguments that challenge their beliefs. For example, if you have a strong belief in a particular political ideology, you may be more likely to accept arguments that support that ideology, and less likely to accept arguments that challenge it. Belief bias can lead to errors in judgment and decision-making, as it can cause people to overlook evidence that contradicts their existing beliefs, and to make decisions that are not supported by the evidence. To avoid belief bias, it is important to carefully evaluate the evidence and arguments that are presented, and to consider them objectively, rather than letting our existing beliefs or biases influence our evaluations or judgments.
