A status quo bias or default bias is a cognitive bias which results from a preference for the maintenance of one's existing state of affairs.[1] The current baseline (or status quo) is taken as a reference point, and any change from that baseline is perceived as a loss or gain. Corresponding to different alternatives, this current baseline or default option is perceived and evaluated by individuals as a positive.[2]
Status quo bias should be distinguished from a rational preference for the status quo, as when the current state of affairs is objectively superior to the available alternatives, or when imperfect information is a significant problem. A large body of evidence, however, shows that status quo bias frequently affects human decision-making. Status quo bias should also be distinguished from psychological inertia, which refers to a lack of intervention in the current course of affairs.
The bias intersects with other non-rational cognitive processes such as loss aversion, in which losses comparative to gains are weighed to a greater extent.[2] Further non-rational cognitive processes include existence bias, endowment effect, longevity, mere exposure, and regret avoidance. Experimental evidence for the detection of status quo bias is seen through the use of the reversal test. A vast amount of experimental and field examples exist. Behaviour in regard to economics, retirement plans, health, and ethical choices show evidence of the status quo bias.
