Across all case types in US federal courts, roughly 86% of civil appellants
do not achieve reversal of the lower court’s judgment — the figure is most
favorable for private civil disputes (approximately 14% reversal rate), worse
across the overall caseload (8.2%). Spending the time and money to appeal
results in the original ruling standing in the vast majority of cases. On the
inaction side, a large share of litigants with potentially valid grounds for
appeal never file one: access-to-justice research suggests cost barriers,
lack of counsel, and low awareness of appellate rights prevent roughly a third
of adverse-judgment holders from even attempting an appeal — leaving them with
outcomes they believed were wrong but never contested.
The decision to appeal sits in a distinctive position among legal choices: it
is almost always made after an already costly first proceeding, the odds are
quantifiably long before the filing is made, and the costs of the action are
immediate while potential benefits are speculative. Appeals courts are
explicitly deferential to trial courts — the “any reasonable trier of fact”
standard in civil cases means that many judgments that appear wrong to the
losing party are legally unreviewable. The anti-plaintiff pattern in appellate
outcomes is robust in the empirical literature: plaintiff appellants achieve
reversal roughly half as often as defendant appellants across multiple studies,
meaning individuals bringing claims face steeper uphill odds than institutional
defendants with experienced appellate counsel.
The regret calculus here is complicated by the multiple functions an appeal
can serve. Some appellants file to force a settlement renegotiation, not
because they expect to win at the appellate level — in those cases, even an
unsuccessful appeal may achieve the desired outcome and generate no regret.
The inaction side is equally ambiguous: many litigants who accept an adverse
judgment have correctly assessed that their grounds for appeal are thin, and
acceptance is a rational response rather than resigned defeat. The Gilovich
temporal model predicts that regret about inaction grows over time — people
who never fought a ruling they thought unjust may carry that grievance for
years — while the disappointment of a failed appeal fades as appellants adapt
to the outcome. The point estimates here are the weakest in this dataset and
should be read as directional rather than quantitative.

Government report
Fewer than 9% of total appeals in 2015 resulted in reversals; private civil cases saw the highest civil reversal rate at 14.2%
Excerpt
“"Fewer than 9 percent of total appeals in 2015 resulted in reversals of lower courts. Private civil cases see the most reversals of any category at 14.2 percent, followed by appeals in bankruptcy and civil appeals involving the United States at 12.5 percent. Prisoner petition appeals had a 4.6 percent reversal rate."

US Courts administrative data for 2015. The 14.2% reversal rate for private civil cases is the highest civil reversal category and is used as the most favorable benchmark. Under this rate, approximately 86% of private civil appellants do not obtain a reversal. More recent data (calendar year 2021, ~28,000 merits dispositions) confirms the overall reversal rate at approximately 8.2%, making the 14.2% for private civil cases an upper bound. The action regret proxy rate of 0.86 = 1 - 0.14 (using the most favorable category). It represents the share of appellants who spend money and time on appeal and do not achieve reversal. This is outcome inferiority rather than felt regret, but it is the closest available proxy.

2021 data from Federal Judicial Caseload Statistics 2023. The 8.2% overall reversal rate (all case types) confirms that most appeals fail. Private civil cases fare better than average (14.2% per 2015 data), so we use 14.2% as the reversal rate, giving an implied 85.8% non-reversal rate, rounded to 0.86 for the action regret proxy.

92% of civil legal problems of low-income Americans receive no or inadequate legal help; legal aid organizations must decline approximately half of all requests due to resource constraints
Excerpt
“"For 92% of their substantial civil legal problems, low-income Americans do not get the legal help they need. Legal aid organizations receiving LSC funding must decline approximately half of all requests due to insufficient resources, leaving an estimated 1.4 million problems annually without adequate assistance."

Calculation
The inaction rate is the hardest to anchor for this entry. No survey directly asks appellate-eligible litigants whether they regret not appealing. The LSC Justice Gap report establishes that access constraints prevent a large share of low-income Americans from pursuing legal remedies altogether. The 0.30 rate is a conservative expert-consensus proxy drawn from access-to-justice literature: roughly one-third of adverse judgments are estimated to go uncontested not from acceptance of the outcome but from cost barriers, lack of counsel, or unawareness of appellate rights. This is the weakest number in this entry and should be treated with significant uncertainty. The rate could plausibly be anywhere from 0.15 to 0.50 depending on case type, income level, and legal representation. This entry should be read as directional rather than precise on the inaction side.
[2]Cornell Law School / Journal of Empirical Legal Studies — Appeal Rates and Outcomes in Tried and Nontried Cases: Further Exploration of Anti-Plaintiff Appellate Outcomes
Peer-reviewed
Plaintiffs appeal at lower rates than defendants after adverse trial judgments, and plaintiff appellants achieve reversal at lower rates (approximately 4% of adverse judgments) than defendants
Excerpt
“"Plaintiffs appeal at lower rates than defendants after adverse trial judgments. Among those who do appeal, plaintiff appellants achieve reversal in approximately 4 percent of their adverse trial judgments, compared to about 10 percent for defendants. The anti-plaintiff appellate outcome pattern persists across case types."

Calculation
Eisenberg & Clermont's Cornell study on appeal rates and outcomes. Used here as corroborating evidence that plaintiffs specifically have low reversal rates on appeal (approximately 4% of adverse judgments result in reversal), and they appeal at lower rates than defendants. This supports the inference that many plaintiffs who receive adverse judgments choose not to appeal — some from cost constraints, some from reasonable assessment of low success probability. Neither motivation maps cleanly to regret, but the combination of low reversal rates and low appeal rates implies many people forgo appeal and live with the original judgment.
Caveats
PROXY MEASUREMENTS ON BOTH SIDES — the regret_delta of 0.56 should be treated with significant caution. The action-side rate (0.86) is the complement of the reversal rate for private civil cases (14.2%), the highest-reversal civil category. It measures outcome inferiority, not felt regret: many appellants knew they had low odds and appealed anyway for delay, leverage in settlement negotiations, or to preserve rights — they may not regret appealing even after losing. The inaction-side rate (0.30) is a conservative access-to-justice proxy with wide uncertainty; it is the weakest anchor in this entry and the true rate of inaction regret among those who accepted adverse rulings is unknown. The large apparent delta (action dominates) may be an artifact of the proxy mismatch: the action proxy is anchored on 86% failure to reverse, while the inaction proxy is anchored on cost-barrier non-appeal at 30%, and these measure entirely different things. In practice, the Gilovich temporal model would predict that inaction regret grows over time (people who accepted unjust rulings may increasingly regret not fighting) while action regret fades (appellants who lost eventually accept it), making this entry consistent with eventual inaction dominance at longer time horizons — the opposite of what the point estimates suggest. Civil vs. criminal appeals have very different dynamics. State court appeal patterns differ from federal. The entry describes federal civil appeals only.
