One-paragraph thesis:

The widespread legal practice of using all-caps in consumer contracts to ensure key terms are conspicuous and consent is improved is deeply flawed. His empirical research demonstrates that all-caps text fails to enhance consumer understanding, provides no benefits for most readers, and significantly harms the comprehension of older individuals. Arbel calls for abandoning this unsubstantiated tradition and exploring more effective disclosure methods.

What this paper is about:

A hallmark of consumer contracts is long blocks of capitalized text. Courts and legislators believe that such “all-caps” clauses improve the quality of consumer consent and thus they will often require the capitalization of certain key terms in consumer contracts. Some of the most important terms in consumer contracts—warranty disclaimers, liability releases, arbitration clauses, and automatic subscriptions—will be enforced only because they appeared in all-caps in the contract. This Article is the first to empirically examine the effectiveness of allcaps with respect to the quality of consumer consent. Using an experimental methodology, the Article finds that all-caps is significantly harmful to older readers while failing to show any appreciable improvement over regular print for others. We collect evidence from standard form agreements used by America’s largest companies and find that, despite—and perhaps because— all-caps is ineffective, it is widely used in nearly three-quarters of consumer contracts. Based on these findings and other evidence reported here, this Article lays out the dangers and risks of continued reliance on all-caps and calls for abandoning all-caps.

Legal reliance on blocks of capital letters is unsupported contract lore rather than an evidence-based method of improving consumer consent

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 3–7, that courts and legislatures inherited all-caps from typewriter-era practice and repeatedly treat it as proof that onerous terms were conspicuous, read, and understood. That policy developed without direct evidence of improved consent and despite early legibility research pointing toward slower reading. This is significant because an untested typographic convention determines whether consequential waivers and disclaimers bind consumers. It connects to contract lore, conspicuousness, informed consent, legal formalism, typography, and evidence-based law.

Consumer inattention to fine print permits firms to shroud onerous terms, creating the no-reading problem that conspicuous disclosure is supposed to solve

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 3–4, that consumers usually know salient price and quantity terms but remain ignorant of arbitration provisions, automatic renewal, damages limits, warranty waivers, and other fine print. Firms can cut costs by hiding unfavorable terms that do not affect demand and may actively make them difficult to process. This is significant because the conspicuousness project responds to a genuine consent failure even if its chosen typography fails. It connects to rational ignorance, shrouded attributes, standard forms, asymmetric information, boilerplate, and consumer consent.

Conspicuous-disclosure rules make typography a gateway to enforcement of especially consequential consumer terms

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 4–6, that statutes and courts often condition enforcement of warranty disclaimers, liability releases, arbitration clauses, automatic subscriptions, and other important terms on conspicuous presentation. Capitalization is frequently treated as strong or dispositive evidence of conspicuousness. This is significant because formatting can determine compensation after wrongful death or serious property loss even when it did not change the consumer’s understanding. It connects to UCC section 2-316, warranty disclaimer, liability waiver, arbitration, automatic renewal, and procedural assent.

Courts and statutes widely equate capitalization with conspicuousness even though the supporting empirical record is absent and legibility evidence is mostly negative

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 11–16, that conspicuousness rules are a dominant response to uninformed contracting and that all-caps has become their principal mechanical implementation. Yet the authors find no empirical validation for improved consent. Typography studies dating to 1928 instead associate capitals with slower reading, plausibly because uniform letter height removes ascenders and descenders. This is significant because doctrine ignored the best available evidence while imposing serious consumer consequences. It connects to mandatory disclosure, conspicuous type, reading speed, ascenders and descenders, judicial notice, and regulatory evidence.

A computational study of standard forms from 500 high-traffic websites measures capitalization in contracts governing hundreds of millions of consumer relationships

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 17–19, that the prevalence of formatting matters to the proof demanded for its effectiveness. They analyze forms from 500 popular websites selected through Alexa traffic rankings and use a Python script to classify capitalization at word, sentence, paragraph, and header levels, defining a capitalized paragraph by an eighty-percent threshold. This is significant because it supplies systematic evidence about legal typography in use rather than relying on memorable cases. It connects to computational legal studies, standard-form contracts, web traffic, text classification, prevalence measurement, and corpus methods.

All-caps is pervasive in major consumer contracts, with roughly seventy-seven percent containing a capitalized paragraph

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 18–20, that about seventy-seven percent of the sampled standard forms contain at least one all-caps paragraph; approximately 17.4 percent of detected headers and nine percent of words are capitalized. Because the sample includes firms such as Amazon, Facebook, Uber, and Dell, these forms structure a vast number of individual relationships. This is significant because even modest comprehension harm is multiplied across widespread contractual use. It connects to boilerplate prevalence, consumer scale, uppercase paragraphs, contract design, online services, and cumulative harm.

The near absence of all-caps from persuasive marketing is evidence against its effectiveness when firms genuinely want consumers to understand a message

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 19–20, that advertising uses many fonts, sizes, colors, and layouts but almost never long blocks of capitals. When firms have direct financial incentives to make attractive information comprehensible, professional guidance tells them to avoid all-caps. The convention appears principally in legal text used to bind consumers. This is significant because firms’ revealed design choices cast doubt on the claim that capitals communicate effectively. It connects to revealed preference, advertising design, copywriting, persuasive communication, legal genre, and disclosure incentives.

Every plausible behavioral justification for all-caps predicts improved recall, whether the mechanism is attention allocation, readability, warning, or slower deliberation

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 20–21, that capitalization might hypothetically direct a limited attention budget, make letters accessible, operate as a fire-siren warning of onerousness, or slow reading enough to promote reflection. Despite different mechanisms, each functional account predicts that the highlighted obligation should be remembered more accurately than ordinary text. This is significant because recall supplies a common, falsifiable outcome for otherwise vague judicial intuitions. It connects to salience, attention budgets, readability, warning signals, deliberation, and testable hypotheses.

All-caps should not satisfy conspicuousness without a meaningful behavioral effect because the error cost is enforcement of unknown and onerous terms

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 21–22, that a purely formal defense is normatively inadequate where capitalization supplies the but-for basis for enforcing a wrongful-death release or comparable limitation. If the type choice does not measurably improve understanding, it cannot plausibly solve nonreading merely by shifting responsibility to the consumer. This is significant because the severity of enforcement error determines how demanding the evidentiary burden should be. It connects to error-cost analysis, formal requirements, burden shifting, meaningful assent, liability releases, and consumer remedies.

A randomized experiment isolates capitalization by presenting 570 American respondents with an identical fifteen-paragraph subscription contract and varying one cancellation paragraph

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 22–27, that a controlled design can overcome confounding in field observation. Participants recruited online read a two-page TideTunes contract adapted from a music-service agreement; one group saw normal print and the other saw the automatic-billing and cancellation paragraph in capitals. They then chose among five cancellation rules without returning to the text. This is significant because randomization makes formatting the key systematic difference between groups. It connects to randomized controlled trials, MTurk, automatic renewal, experimental contracts, treatment assignment, and recall measurement.

The experiment uses demographic comparison, geolocation, digital fingerprints, attention checks, reading time, and multiple answer choices to improve response validity

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 22–27, that online samples require quality controls. The study compares sample demographics with the United States, uses Positly screening, verifies unique domestic participants through digital fingerprints and geolocation, includes attention checks, records an average 102-second reading period, and offers five plausible answers to reduce guessing. This is significant because the credibility of a null or harmful effect depends on subjects actually engaging with the contract. It connects to data quality, sample representativeness, attention checks, geolocation, statistical power, and construct validity.

Capitalizing the cancellation paragraph produced no improvement at all in respondents’ ability to identify the contract’s cancellation rule

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 27–30, that the primary experiment yielded the same proportion of correct answers in the all-caps and low-caps conditions. A non-inferiority analysis also rejects the hypothesis that capitalization supplied a policy-relevant benefit of ten percentage points or more. Thus the result is not merely a failure to obtain conventional statistical significance; the data affirmatively undermine a meaningful benefit. This is significant because the dominant legal convention failed its central comprehension test. It connects to null results, non-inferiority testing, statistical power, contract recall, conspicuousness, and evidence-based doctrine.

All-caps did not act as a fire-siren warning that alerted readers to the existence or importance of the tested cancellation term

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 29–30, that the data provide no support for the fire-siren theory. Readers exposed to the capitalized paragraph were no more likely to retrieve the automatic-renewal and cancellation rule than readers who saw ordinary type. A visual signal cannot justify enforcement as a warning if it does not change the relevant response. This is significant because conspicuousness doctrine often assumes that visual distinctiveness itself creates notice. It connects to salience, warning design, attention capture, inquiry notice, automatic renewal, and consumer cognition.

All-caps substantially harmed older readers: respondents over fifty-five made errors at roughly twice the rate of peers who saw low-caps text

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 30–32, that capitalization has a sharply heterogeneous age effect. Among respondents older than fifty-five, about sixty percent in the all-caps condition answered incorrectly, compared with about thirty-one percent in the low-caps condition—a twenty-nine-point difference. The estimated effect for younger participants was negligible. This is significant because a supposed consumer-protection device may selectively burden a vulnerable group rather than merely fail on average. It connects to aging and vision, heterogeneous treatment effects, accessibility, disparate impact, consumer vulnerability, and inclusive design.

A null average benefit combined with substantial harm to older readers shifts the justificatory burden to defenders of all-caps

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 30–32, that the conventional presumption should reverse. The primary study finds no general comprehension gain and evidence of substantial harm among older participants, while capitalization can determine whether onerous clauses are enforced. On that evidence, continued reliance requires an affirmative justification rather than inertia. This is significant because it reframes a familiar drafting practice as an intervention that must earn legal legitimacy. It connects to precaution, evidentiary burdens, status quo bias, age-sensitive regulation, contract enforcement, and empirical legal studies.

A second experiment tests whether all-caps becomes useful under severe time pressure by randomizing capitalization across three short contracts with strict reading limits

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 32–34, that any attention-allocation advantage should be most visible when readers have little time. Eighty-one participants encountered three contracts with key clauses randomly shown in capitals or ordinary type and faced respective reading limits of twenty-three, twenty, and fifteen seconds, producing 240 usable responses. This is significant because the design gives the salience theory a deliberately favorable stress test. It connects to bounded attention, time scarcity, randomized experiments, contract skimming, cognitive load, and ecological validity.

Even under strict time pressure, all-caps did not improve accuracy and ordinary type performed somewhat better in two of the three tests

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 34–35, that the timed study supplies no evidence of a capitalization advantage. Low-caps participants did somewhat better in the second and third contracts, although only one comparison approached conventional significance and the study was underpowered. The authors therefore treat the pattern cautiously while emphasizing that it again fails to rescue the fire-siren theory. This is significant because the format remains ineffective under the condition thought most likely to favor it. It connects to time pressure, exploratory evidence, statistical uncertainty, attention allocation, replication, and contract design.

Readers rated an all-caps contract substantially harder to read and somewhat harder to understand than the same contract in ordinary type

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 35–38, that subjective experience points in the opposite direction from the convention’s justification. In a 102-person study, respondents randomly assigned the fully capitalized contract rated it about twenty-two percent harder to read, a statistically significant difference, and about thirteen percent harder to understand, a difference that was not statistically significant. This is significant because conspicuousness should facilitate access to information rather than impose perceptual friction. It connects to readability, subjective difficulty, typography, cognitive fluency, user experience, and informed consent.

All-caps readers took about thirteen percent longer to finish, a directionally important but statistically inconclusive result

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 38–39, that capitalization may slow readers rather than promote efficient review. Participants assigned all-caps took about 94.7 seconds on average, compared with 83.4 seconds for low-caps, but large variance prevented a statistically confident conclusion. The authors note that reading-time data may also mix careful reading with skimming or disengagement. This is significant because slower processing would compound the costs of already unread standard forms. It connects to reading speed, processing fluency, measurement error, skimming, transaction costs, and accessibility.

A four-arm experiment compares ordinary type, all-caps, a boxed clause, and bolding only the key sentence in a recreational-vehicle liability disclaimer

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 39–41, that comparative design can ask whether capitalization fails because disclosure design is futile or because lawyers chose the wrong intervention. The 241-person experiment presents a recreational-vehicle rental agreement and randomizes the liability disclaimer among low-caps, all-caps, a box, and selective bolding of the dispositive sentence. Questions separately test on-road and off-road injuries. This is significant because it benchmarks the legal default against plausible alternatives in the same text. It connects to comparative treatment design, liability waivers, selective emphasis, visual borders, comprehension testing, and legal design.

Selectively bolding the key sentence produced the lowest error rates and substantially outperformed ordinary text on the main liability question

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 41–43, that targeted bolding is a promising alternative to blanket capitalization. On the on-road-liability question, the bold condition produced a twenty-seven-percent error rate, compared with fifty-seven percent for low-caps, fifty-two percent for all-caps, and forty-eight percent for the box. On the off-road question, bold again had the lowest error rate—thirteen percent, versus twenty-one, thirty, and twenty-four percent—although that comparison was not statistically significant. This is significant because a simple design change can materially improve comprehension where the canonical method cannot. It connects to selective salience, information hierarchy, liability disclaimers, effect size, visual design, and consumer understanding.

The bolding result is an existence proof that contract presentation can improve understanding, not a universal prescription for bold text

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 41–44, that selective bolding should be treated as an existence theorem rather than a finished regulatory formula. It shows that readers can respond to a well-targeted intervention, which makes the persistent failure of blanket capitals more informative. Yet only one bolding comparison was statistically significant, other attempted interventions did not succeed, and effective design is likely contextual. This is significant because it preserves the possibility of useful disclosure without converting one experiment into new drafting lore. It connects to proof of concept, replication, context-sensitive design, behavioral interventions, external validity, and regulatory humility.

Judicial reliance on all-caps has concrete high-stakes consequences, including denial of personal-injury recovery and enforcement of class-action waivers

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 45–47, that typography is not a harmless drafting eccentricity. Courts have invoked capitalized text when enforcing releases that foreclose compensation for serious injuries and clauses that prevent collective litigation. A person’s substantive legal position may therefore turn on a convention that the experiments find ineffective or harmful. This is significant because the costs of a false inference of notice are borne in lost remedies, not just awkward reading. It connects to exculpatory clauses, personal injury, class-action waivers, procedural rights, meaningful assent, and access to justice.

A formal all-caps safe haven gives firms incentives to satisfy the appearance of disclosure while preserving consumer ignorance

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 45–48, that the legal convention can align form with strategic nondisclosure. A firm obtains an enforcement advantage by capitalizing onerous language even if the format does not improve comprehension and may make reading harder. The contrast with marketing is revealing: when firms want audiences to understand favorable claims, they generally avoid long capitalized blocks. This is significant because a rule intended to discipline drafters may instead give them a cheap way to manufacture consent. It connects to safe harbors, strategic compliance, shrouded attributes, firm incentives, revealed preference, and consumer exploitation.

Courts and lawmakers should stop assigning all-caps any special weight in deciding whether a term was conspicuous or knowingly accepted

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 45–50, that the legal system should abandon its reliance on capitalization. The case rests on mutually reinforcing considerations: no affirmative empirical foundation supported adoption; prior reading research predicts difficulty; the authors’ main and exploratory studies show no benefit and possible harm; industry avoids capitals when comprehension matters; and erroneous enforcement can impose grave losses. This is significant because the remedy is not merely better drafting advice but removal of an evidentiary shortcut from contract doctrine. It connects to doctrinal abandonment, conspicuousness, evidentiary weight, judicial notice, statutory reform, and contract legitimacy.

Replacing all-caps with another universal formatting safe haven would recreate the same vulnerability to manipulation and contextual mismatch

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 50–51, that reform should not simply canonize a new font treatment. Any mechanical rule can be gamed by surrounding the nominally emphasized term with distracting text, overusing the required signal, or ignoring how the term functions in the document and transaction. Conspicuousness is relational and contextual, not an intrinsic property of a single typographic command. This is significant because it cautions against rebuilding the failed formalism under a different visual label. It connects to rules and standards, regulatory arbitrage, information overload, contextual interpretation, salience dilution, and legal formalism.

Contract design should separate a salient notice marker or heading from a readable low-caps explanation of the legal term

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 51–52, that two distinct disclosure functions need not be forced into the same typography. A brief heading, icon, or selectively bold sentence can alert a reader that an important issue exists, while the operative body remains in ordinary type that is easier to process. Blanket capitalization tries to supply both notice and explanation and may accomplish neither. This is significant because separating attention capture from substantive communication opens a more coherent design space. It connects to layered notice, information architecture, headings, icons, plain language, and progressive disclosure.

Failure of the leading conspicuousness device supports skepticism about disclosure mandates, while success of selective bolding shows that disclosure is not necessarily futile

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 52–53, that the evidence cuts in two directions in the broader debate over mandatory disclosure. The entrenched intervention fails despite extraordinary legal confidence, which reinforces concern about untested disclosure mandates. But selective bolding improves performance in one study, indicating that presentation can sometimes help readers. This is significant because the right lesson is empirical discrimination among interventions, not categorical faith in or rejection of disclosure. It connects to mandatory disclosure, behavioral law and economics, policy experimentation, evidence-based regulation, debiasing, and consumer information.

Onerous terms should be presumptively unenforceable unless the drafting firm can show that its disclosure method effectively communicated them

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 53–54, that conspicuousness should become performance-based. Instead of courts assuming that a prescribed format creates notice, a firm seeking to enforce an onerous term should bear the burden of showing that its chosen presentation actually communicated the term effectively. The default would be nonenforcement when that proof is absent. This is significant because it replaces a typographic proxy with an outcome-oriented accountability rule. It connects to burden shifting, performance standards, unconscionability, informed consent, evidentiary proof, and default rules.

A performance rule would use firms’ existing A/B-testing capacity to generate innovation and cumulative knowledge about effective contract communication

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 53–55, that firms are better positioned than courts or consumers to test competing presentations at scale. Companies routinely A/B test marketing and interface choices; if enforceability required effective communication, that capacity could be redirected toward contract terms. Successful practices could diffuse, while drafters would have skin in the game rather than receiving a free safe harbor. This is significant because the reform harnesses private experimentation to build an evidence base that doctrine currently lacks. It connects to A/B testing, regulatory incentives, innovation, information production, compliance design, and organizational learning.

Disclosure should be evaluated for vulnerable subgroups and may properly minimize misunderstanding rather than maximize average comprehension

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 54–55, that average treatment effects are an inadequate target when an intervention harms identifiable readers. Because the primary study shows a large adverse effect among older participants, a disclosure method that modestly raises the mean could still be unacceptable if it imposes concentrated misunderstanding. Regulators might therefore minimize error across groups or set protective floors. This is significant because accessibility and distribution belong inside the definition of effective communication. It connects to heterogeneous effects, vulnerability, social welfare functions, distributional analysis, universal design, and anti-discrimination norms.

Contract law should abandon untested all-caps formalism, demand proof from firms, and pursue targeted methods that genuinely help consumers understand consequential terms

Professor Yonathan A. Arbel and Andrew Toler claim, in “ALL-CAPS” on manuscript pages 55–56, that capitalization should lose its privileged role in contract enforcement. Across prevalence evidence, a large primary experiment, exploratory tests, reader reports, and an alternative-format study, capitals do not improve comprehension and may harm older readers, while targeted highlighting shows qualified promise. The authors would shift proof to firms and encourage empirically validated design. This is significant because it turns an examination of typography into a general program for evidence-based consent. It connects to contract modernization, consumer protection, empirical legal reform, legal design, performance regulation, and meaningful choice.
