Belief Bias



Let’s talk about cognitive biases: BELIEF BIAS

The belief bias describes the tendency to evaluate the strength of an argument by virtue of how believable the conclusion is (to you).

It’s a form of confirmation bias because conclusions that you find believable tend to be those that support your preexisting beliefs.

For example, someone could say “pelicans are birds, and all birds fly. Therefore, pelicans fly.” Seems to make sense, right? We know that birds tend to fly, so the conclusion seems believable to us. However, upon further thought, we may realize that not all birds fly (e.g., penguins), making the argument fallacious.
