status quo bias can also be a rational route if there are cognitive or informational limitations. Informational limitations Decision outcomes are rarely certain, nor is the utility they may bring. Because some errors are more costly than others (Haselton & Nettle, 2006), sticking with what worked in the past is a safe option, as long as previous decisions are "good enough". Cognitive limitations Cognitive limitations of status quo bias involve the cognitive cost of choice, in which decisions are more susceptible to postponement as increased alternatives are added to the choice set. Moreover, mental effort needed to maintain status quo alternatives would often be lesser and easier, resulting in a superior choice's benefit being outweighed by decision-making cognitive costs. Consequently, maintenance of current or previous state of affairs would be regarded as the easier alternative. Irrational routes The irrational maintenance of the status quo bias links and confounds many cognitive biases. Existence bias An assumption of longevity and goodness are part of the status quo bias. People treat existence as a prima facie case for goodness, aesthetic and longevity increases this preference. The status quo bias affects people's preferences; people report preferences for what they are likely rather than unlikely to receive. People simply assume, with little reason or deliberation, the goodness of existing states. Longevity is a corollary of the existence bias: if existence is good, longer existence should be better. This thinking resembles quasi-evolutionary notions of "survival of the fittest", and also the augmentation principle in attribution theory. Psychological Inertia is another reason used to explain a bias towards the status quo. Another explanation is fear of regret in making a wrong decision, i.e. If we choose a partner, when we think there could be someone better out there. Mere exposure Mere exposure is an explanation for the status quo bias. Existing states are encountered more frequently than non-existent states and because of this they will be perceived as more true and evaluated more preferably. One way to increase liking for something is repeated exposure over time. Loss aversion Loss aversion also leads to greater regret for action than for inaction; more regret is experienced when a decision changes the status quo than when it maintains it. Together these forces provide an advantage for the status quo; people are motivated to do nothing or to maintain current or previous decisions. Change is avoided, and decision makers stick with
