Status Quo Bias
The disproportionate tendency to choose or stay with the current state, default, or previously chosen option even when costless, clearly-labeled alternatives would serve as well or better.
“A series of decision-making experiments shows that individuals disproportionately stick with the status quo.”

Provenance
Where it was first filed
William Samuelson & Richard Zeckhauser, 1988 — Status Quo Bias in Decision Making. Coined the term and gave the first experimental demonstration. Subjects answered decision problems either with options presented neutrally or with one option framed as the existing status quo; the status-quo label substantially raised that option's selection rate. The paper paired the lab experiments with field data on Harvard employees' health-plan choices and faculty TIAA/CREF retirement allocations, where existing enrollees changed allocations far less than new enrollees.

Tested variation 1
Original questionnaire experiments
Labeling an option as the status quo significantly increased the probability it was chosen; the bias grew with the number of alternatives and shrank when the subject had a strong independent preference.
William Samuelson & Richard Zeckhauser, 1988 · yield Not reported as a single standardized effect size in the original paper; reported as significant shifts in choice proportions across framings. · 486 students (mostly first-year MBAs at Boston University School of Management plus public-policy students at Harvard Kennedy School)

Tested variation 2
Field study: organ-donation default (online experiment)
Effective consent to be a donor was far higher under the opt-out default than the opt-in default; the neutral condition was close to opt-out. Cross-national data showed opt-out (presumed-consent) countries had dramatically higher effective consent and significantly higher actual donation rates.
Eric J. Johnson & Daniel G. Goldstein, 2003 · yield 42% consent under opt-in vs 82% under opt-out (79% neutral); roughly a doubling of consent · 161 U.S. online respondents (plus cross-country panel of European nations)

Tested variation 3
Field study: automatic 401(k) enrollment
Participation rose sharply under auto-enrollment, and most auto-enrollees passively stuck with the employer-set default contribution rate and default fund—an allocation almost no prior cohort had actively chosen.
Brigitte C. Madrian & Dennis F. Shea, 2001 · yield Under auto-enrollment ~75% of participants stayed at the 3% default contribution rate and ~80% in the default fund; ~61% changed nothing from the defaults · Administrative records of employees at one large U.S. corporation

Pre-registered replication
Strong support for status quo bias in three scenarios (budget allocation, investment portfolios, college job offers); failed to find conclusive support in the wagon/car-color scenario.
Qinyu Xiao, Choi Shan Lam, Muhrajan Piara & Gilad Feldman, 2021 · yield Cohen's h around 0.38–0.52 for the replicating scenarios; below-small (h≈0.19, non-significant) for the failed wagon-color comparison · N1 = 311, N2 = 316 U.S. MTurk participants

Method
How the judgment forms
Samuelson and Zeckhauser attributed status quo bias to several coexisting forces: loss aversion (losses from departing the status quo loom larger than equivalent gains, per prospect theory), the cognitive and transaction costs of deliberation, regret avoidance (omission errors feel less painful than commission errors), and a preference for consistency/commitment. Defaults additionally signal an implied recommendation and exploit inattention/procrastination, which is why field default effects (organ donation, auto-enrollment) are so large.
A live debate is whether status quo bias is genuinely distinct from the 'default effect' or whether studies conflate them: a registered report (Yam & Feldman) argues that Dinner et al. (2011), often cited for default effects, arguably measured status quo bias instead. Loss aversion as the master mechanism is also contested, since defaults move behavior even with negligible stakes and one-click reversibility, pointing to implied endorsement and effort/attention rather than valuation asymmetry alone.

Verdict · replication
robust
The lab effect held in a 2021 pre-registered replication (Xiao, Lam, Piara & Feldman) in 3 of 4 original Samuelson–Zeckhauser scenarios, with effect sizes around Cohen's h 0.38–0.52; the wagon-color scenario failed. The closely related default effect is among the most reliably reproduced findings in behavioral science (organ-donation defaults, 401(k) auto-enrollment), though scholars increasingly stress that 'status quo bias' and 'default effect' are sometimes conflated and that boundary conditions matter.

On record
Documented in the wild
Organ-donation consent gap between opt-in and opt-out countries · 2003
Johnson & Goldstein documented that countries with opt-out (presumed-consent) defaults had vastly higher effective donor consent than opt-in countries (e.g., Austria near-universal vs Germany around 12%), and a controlled online experiment showed consent of 42% under an opt-in default vs 82% under an opt-out default with one-click reversibility.
401(k) automatic-enrollment inertia at a large U.S. firm · 2001
After the firm switched to automatic enrollment, most employees passively remained at the default 3% contribution rate and default fund—an outcome almost no prior cohort had actively selected—demonstrating large-scale status quo/default inertia in retirement saving.
New Jersey vs Pennsylvania auto-insurance 'right to sue' default · 2004
New Jersey defaulted drivers into a limited right to sue (cheaper) while Pennsylvania defaulted them into the full right to sue; drivers overwhelmingly kept whichever option was their state's default (79% of NJ drivers kept the limited right; 70% of PA drivers kept the full right), showing default-driven status quo retention in a high-stakes consumer-law setting.

Final frame · the counter-move
Force an active, symmetric choice: strip the 'current'/'default' label, ask 'if we were starting fresh today with none of these in place, which would we pick?', and where appropriate set the default to the option you'd want chosen by reflection (since defaults are sticky either way).
Default-switching field experiments show the choice architecture, not stable preferences, drives outcomes—e.g., organ-donor consent moved from 42% to 82% purely by flipping the default with one-click reversibility, implying the same lever can be set to counter inertia.

Adjacent reels
- Default EffectThe behavioral lever that produces much real-world status quo bias: people disproportionately accept whatever option is pre-set. Often used interchangeably, but scholars argue they are conceptually distinct (a default need not be the pre-existing state).
- Endowment EffectInflated valuation of items one already owns; like status quo bias it stems from loss aversion, but it requires possession/ownership whereas status quo bias applies to defaults and baselines without ownership (Kahneman, Knetsch & Thaler 1991).
- Loss AversionProposed core driver: leaving the status quo means weighing forgone reference-point holdings as losses, which loom larger than equivalent gains.
- Omission BiasPreference for inaction over action contributes to status quo retention because errors of omission feel less blameworthy/regrettable than errors of commission.
- Sunk Cost FallacyBoth produce persistence with a current course, but sunk cost is driven by prior irrecoverable investment, whereas status quo bias needs no prior investment—just the option being the current/default state.
