What Is Status Quo Bias? Preferring Things to Stay as They Are

Presented with the same set of options, people select the one labelled as current or as the default considerably more often than when the same option is presented without that label. The effect has been demonstrated in experiments where the options are held constant and only which one counts as the status quo is varied, which isolates it from any genuine advantage of the existing arrangement. It appears in real decisions about pension allocation, insurance, energy supplier and medical treatment, and the differences in outcome between defaults are frequently enormous, with participation rates in retirement schemes differing by tens of percentage points depending on whether enrolment is automatic. The size of those real-world differences is what makes the effect consequential rather than a laboratory curiosity.

Several mechanisms contribute and they are not exclusive:

• •Loss aversion, since moving away from the current state means giving up what it provides, which registers as a loss
• •Regret avoidance, since a bad outcome following action feels worse than the same outcome following inaction
• •Effort, since evaluating alternatives costs attention and the default requires none
• •Implied recommendation, since people reasonably infer that a default was chosen by someone who knew what they were doing
• •Uncertainty, since the current arrangement's outcomes are known and alternatives are not
• •Genuine switching costs, which are a real reason rather than a bias and must be separated from the rest

Because defaults carry so much weight, whoever sets them exercises real influence, and that fact has generated a policy literature and an ethical argument. Automatic enrolment in pension schemes with an option to leave raises participation dramatically compared with requiring people to opt in, which is the most cited application. Organ donation rates differ substantially between countries with opt-in and opt-out registration, though the relationship is complicated by other differences in how the systems work and the effect is smaller than the raw comparison suggests. Default settings in software determine what nearly everyone uses. The ethical question is whether deliberately exploiting the effect respects autonomy, since the person retains the choice and is being steered, and the answer offered by advocates is that some default must be set and setting it thoughtfully is better than setting it carelessly.

The power of defaults raises a question about who sets them, which applies well beyond deliberate policy. Software configurations are chosen by developers and are adopted by nearly all users, so privacy settings, data sharing and notification behaviour are determined by whoever wrote them. Contract terms are drafted by one party and accepted by the other without negotiation. Pension fund allocations are set by administrators. Medical pathways embed defaults in forms and systems. In each case somebody chose, frequently without considering that they were choosing for everyone, and the resulting arrangement carries the force the effect gives it. Recognising that there is no neutral default, since some option must be presented first or presented as standard, converts the question from whether to influence choices into how to do it responsibly, which is the argument advocates of the approach make.

Treating every preference for the existing arrangement as an error is itself a mistake and the qualifications matter. Existing arrangements have survived, which is weak evidence that they work, and a proposal to change something that has operated for a long time should carry some burden of explaining why it persisted. Switching costs are real. Uncertainty about alternatives is a genuine reason for caution where the current outcome is acceptable. And the information available about an existing arrangement is more reliable than projections about an alternative, which is a rational basis for discounting the latter. The bias is the residual after all of those are accounted for, and separating it from them in any particular case is difficult, which is why an accusation of status quo bias is frequently a rhetorical move rather than a diagnosis.

The same option is chosen more often when labelled as current or default, demonstrated with the options held constant. Loss aversion, regret avoidance, effort and the inference that a default was recommended all contribute. Automatic enrolment raises pension participation by tens of percentage points. Genuine switching costs and the evidence that an arrangement has survived are reasons rather than bias.
