Belief bias is when a person tends to favor an argument on the basis of their personal beliefs about its conclusion, rather than the strength of the argument itself.
In general, people are more likely to be less critical of conclusions that they agree with, and more critical of those that they disagree with.
Agreement with a conclusion tends to stem from an individual’s personal values, beliefs, and knowledge.
Example of Belief Bias
- A politican that you agree with on most matters proposes a new type of policy. Agreeing with this policy without forming an understanding of the details is an example of belief bias.
