People are biased toward beliefs that are welcomed by their in-group. Some beliefs produced by these biases—such as climate change denial and religious belief—can be fruitfully modeled by signaling theory. The idea is that the beliefs function so as to be detected by others and manipulate their behavior, primarily for the benefits that accrue from favorable tribal self-presentation. Signaling theory can explain the etiology, distinctive form, proper function, and alterability of these beliefs.
