Semantically similar decisions — same territory, different trade-offs.
61% of plaintiffs who rejected the defendant’s last settlement offer and
proceeded to trial received an equal or worse financial outcome than the offer
they turned down, according to Kiser, Asher and McShane’s 2008 analysis of
2,054 California civil cases — the largest empirical study of settlement
decision-making errors in the published legal literature. The average cost of
that error was $43,100. On the inaction side, the Legal Services Corporation’s
2022 Justice Gap report found that 74% of low-income Americans who experienced
a substantial civil legal problem received no legal help at all — leaving the
majority of valid legal claims entirely unresolved. The data points in opposite
directions: the majority of those who fight tend to lose relative to the
settlement on the table, and the majority of those who never enter the legal
system leave their problem unaddressed.
The asymmetry between plaintiffs and defendants in the Kiser study deserves
attention. Defendants made the wrong decision (rejected an offer that turned
out better than the judgment) only 24% of the time, compared to 61% for
plaintiffs. This gap reflects a systematic pattern: plaintiffs tend to
overestimate the strength of their case and underestimate legal costs, while
defendants — typically insurance carriers or repeat litigants with actuarial
experience — calibrate more accurately. The average defendant error cost was
far higher ($1.14 million) when defendants did lose, but the frequency of
error was much lower. For most individual plaintiffs who are one-time
litigants, the risk is that optimism about court outcomes drives rejection of
settlements that would have served them better.
Both proxies measure something real but neither measures regret directly.
The 61% outcome-error rate captures financial inferiority, not necessarily
felt regret — some plaintiffs pursued litigation for non-financial reasons
(vindication, precedent, principle) and may not regret the decision even
after losing on the financial metric. The 74% non-engagement figure captures
the scale of unresolved legal problems among people without resources, not
the subjective experience of wishing they had acted. Case type and jurisdiction
affect the action-side figures substantially: the Kiser dataset draws from
California civil litigation and skews toward personal injury and products
liability, which have higher plaintiff error rates than contract or employment
disputes. Inheritance disputes, tax challenges, and small claims have
structurally different regret dynamics and are not well captured by either
source.

Peer-reviewed
Plaintiffs made the wrong decision in rejecting the defendant's last settlement offer in 61.2% of cases; average cost of plaintiff decision error: $43,100
Excerpt
“"Plaintiffs made the wrong decision in rejecting the defendant's last settlement offer or last demand in 61.2 percent of the cases. The average cost of the plaintiff decision error was $43,100. In products liability cases, plaintiffs in 61 percent to 69 percent of cases either recovered nothing or less than the defendant's offer."

Calculation
Kiser, Asher & McShane (2008) analyzed 2,054 contested civil cases in California in which both plaintiffs and defendants made settlement demands, rejected offers, and proceeded to arbitration or trial. "Decision error" = plaintiff's final outcome was equal to or worse than the defendant's last settlement offer. The 61.2% plaintiff error rate is used directly as the action-regret proxy: the majority of litigants who chose to fight rather than settle received an inferior financial result. This is not a survey of felt regret but a direct measurement of outcome inferiority — the closest available proxy for ex-post decision regret in civil litigation.

Government report
92% of the civil legal problems of low-income Americans received no or inadequate legal help; 74% of those who experienced a substantial problem received no legal help at all
Excerpt
“"Low-income Americans will face approximately 1.7 billion civil legal problems per year. For 92% of their substantial civil legal problems, low-income Americans do not get the legal help they need. 74% of low-income adults who experienced a civil legal problem in the prior year received no legal help whatsoever for their most serious problem."

Calculation
Legal Services Corporation contracted NORC at the University of Chicago for a nationally representative survey of approximately 5,000 US adults below 125% of the federal poverty line. The 74% figure measures the share of people with a substantial civil legal problem who received zero legal help — not purely regret, but the share who took no action and were left without resolution. This is the best available proxy for inaction regret: the overwhelming majority of people with real civil legal problems never engaged the legal system at all. The broader 92% "no or inadequate help" figure encompasses partial help. We use 0.74 as the inaction regret proxy rate because it represents total non-engagement — the clearest analog to "did not pursue the claim."
[2]RAND Corporation — The Perception of Justice: Tort Litigants' Views of Trial, Court-Annexed Arbitration, and Judicial Settlement Conferences
Reference source
Tort litigants' satisfaction was higher with arbitration and trial than with judicial settlement conferences, suggesting procedural participation has intrinsic value beyond financial outcomes
Excerpt
“"The three procedures studied — trial, court-annexed arbitration, and judicial settlement — differed considerably in the procedural fairness and satisfaction ratings they engendered, with arbitration hearings and trials viewed more favorably than settlement conferences. Tort litigants were sensitive to procedural variations, wanting a dignified, careful, and unbiased hearing of their cases."

Calculation
RAND R-3708 surveyed 286 litigants across three state courts. Used here as the corroborating source for the value of legal participation — it demonstrates that people who engage the legal process (even in settlement conferences) report higher procedural satisfaction than those who do not. This supports the inference that non-engagement (inaction) correlates with lower procedural satisfaction and potentially greater regret, though it does not directly measure inaction regret.
Caveats
PROXY MEASUREMENTS ON BOTH SIDES. Neither side uses a direct regret survey. The action rate (0.61) is Kiser et al.'s outcome-error rate from 2,054 California cases: it measures financial outcome inferiority relative to the last settlement offer, not felt regret. Plaintiffs who lost at trial but preferred the process, or who had non-financial goals (vindication, precedent), are counted as "errors" even if they do not regret litigating. The inaction rate (0.74) is the LSC Justice Gap figure for total non-engagement with the legal system among people who had a substantial civil legal problem — this is a barrier-to-access measure, not a direct regret measure. It may substantially overstate actionable regret (many non-engagers may have concluded that their problem did not warrant legal action) or understate it (those who did not know legal remedies were available cannot articulate specific regret). The two populations are structurally incomparable: Kiser's litigants had already reached negotiation; LSC's population had not entered the legal system at all. Case type matters enormously: plaintiff decision errors are highest in products liability (61-69%) and personal injury, lower in contract and employment disputes where plaintiff win rates are higher. In small claims, inheritance disputes, and tax matters, the relevant regret dynamics differ substantially from the California civil litigation sample. The Gilovich inaction-dominance pattern is plausible here — most people who never pursued a valid claim may carry longer-term regret than those who fought and lost — but the data gap on the inaction side means the delta of -0.13 should be read as directional rather than precise.
