Practical Significance
Many social institutions rely on individuals to make rational judgments. A fair jury trial, for example, requires that the jury ignore irrelevant features of the case, weigh the relevant features appropriately, consider different possibilities open-mindedly and resist fallacies such as appeal to emotion. The various biases demonstrated in these psychological experiments suggest that people will frequently fail to do all these things. However, they fail to do so in systematic, directional ways that are predictable.
Cognitive biases are also related to the persistence of superstition, to large social issues such as prejudice, and they also work as a hindrance in the acceptance of scientific non-intuitive knowledge by the public.
