Steve Krug published the third edition of _Don't Make Me Think_ in 2014. In the eleven years since, the technology, the audience, and the regulatory landscape around digital usability have all shifted further than his book could have anticipated. Mobile is now the default. AI is now reading and writing the page alongside the user. Dark patterns are now a named federal violation, not a designer-ethics topic. Cookie consent is now a legal exposure for any business large enough to run analytics.
What has not changed: Krug's principles. Don't make me think. Make scanning easy. Omit needless words. Treat usability as common courtesy. Eleven years later they still describe how human attention works on the web. They are not laws — they are heuristics that hold under most conditions and break under specific ones — but they remain the right starting frame.
This hub is the modernized reading list. The keystone essay anchors the cluster: the cost of misapplying Krug's principles now shows up in places your dashboard cannot see. The spoke articles work through the chapter-aligned principles, the dark-patterns micro-cluster, and the CRO cross-links — each modernized with current research, current regulatory context, and the SHADOW framework for measuring the costs your funnel cannot.
If you are building, optimizing, or shipping any digital product in 2026, this is the field guide.
The editorial stance
Every article in this cluster is written from the same point of view, which it is worth stating explicitly:
Krug's principles still hold — but they're not laws. They're heuristics that break under specific competitive, technical, and audience conditions. The cost of misapplying them shows up in places your dashboard can't see: brand erosion, legal exposure, and word-of-mouth damage. Test in your context. Don't trust blindly.
This stance shows up as five recurring editorial moves throughout the cluster:
- Respect the source. Krug, Brignull, the Princeton CITP work, the Norwegian Consumer Council reports — these are cited and built on, not rebutted.
- Surface conditions. When a principle holds and when it breaks. Anchoring works when product is differentiated; breaks when commodity. Multi-step forms work when motivation is high; fail when motivation is low.
- Test, don't trust. Tools, frameworks, and tactics are starting hypotheses. Real answers come from your A/B tests in your environment with your audience — and from extending those tests to capture the SHADOW proxies your funnel cannot.
- Surface the unmeasured. Connect every UX failure to its second-order cost — word-of-mouth, brand decay, legal exposure, employee trust. The dashboard only shows the funnel.
- Respect the buyer. The reader is often a CMO, VP Growth, or CEO who approves consulting engagements, not a practitioner. Articles in this cluster are written with that audience in mind.
If you are a practitioner reader, the cluster is still useful — but the framing is "what your buyer needs to understand to fund this work."
The flagship: the unmeasured cost of bad UX
Read this first. Every spoke in the cluster links back to it.
[The Unmeasured Cost of Bad UX: What Your Funnel Won't Show You](/usability/the-unmeasured-cost-of-bad-ux/)
Your funnel measures who showed up. It cannot measure who never came back, who told their coworkers to stay away, or who triggered a class action. The keystone essay walks through the four invisible costs (word-of-mouth, legal exposure, employee trust collapse, brand half-life), the structural reasons your dashboard is blind to them, and the SHADOW framework — six proxies you can read alongside your funnel to surface the costs sooner.
If you read only one piece in this cluster, read the keystone. The rest of the hub is organized as the spokes that link back to it.
The SHADOW framework
A six-proxy audit for finding UX costs your funnel does not show you. Each proxy reads on a slower clock than funnel metrics; the framework is designed to be run quarterly alongside your CRO program.
| Letter | Proxy | What to track |
|---|---|---|
| S | Sentiment | Brand-search drift, social-mention sentiment, review-platform tone |
| H | Help-desk volume by reason | Support ticket clusters tied to UX patterns, not just topics |
| A | Audits — legal & accessibility | ADA Title III, GDPR/CCPA, FTC Click-to-Cancel exposure |
| D | Defection reasons | Cancellation free-text, exit interviews, churn-survey themes |
| O | Outside reviews | G2, Trustpilot, App Store, Capterra — analyzed by theme, not stars |
| W | Word-of-mouth | NPS detractor counts × industry-standard negative-WOM coefficients |
Download the one-page SHADOW audit framework and run it on your own program in an afternoon. Or read the keystone essay for the full economic argument behind why these six proxies matter.
Chapter-aligned spokes (modernized Krug)
Each spoke takes a chapter or chapters from _Don't Make Me Think_, holds Krug's principle as the starting frame, and updates it for 2026 mobile-first, AI-native, dark-pattern-regulated reality.

The dark-patterns micro-cluster
Dark patterns are no longer a designer-ethics topic. The FTC, the EU's Digital Services Act, California's CCPA regulations, and a growing body of state law have made the most common patterns federal-or-state violations. The micro-cluster covers the taxonomy, the alternatives, the compliance flows, and the case studies.
- [The 12-Pattern Taxonomy](/dark-patterns/taxonomy/) — The complete reference catalog. For each of the twelve dark patterns, the definition, the canonical example, and the current legal cost-to-ship. Includes the three-tier risk model (currently illegal / increasingly enforced / brand cost only) for sequencing remediation.
- [Bright Patterns: The Ethical Alternative](/dark-patterns/bright-patterns/) — The counter-catalog. For each dark pattern, the bright-pattern alternative, the real-world example, and the reason your A/B test will systematically misjudge the trade-off. Includes the "default-bright" design principle for inverting the burden of proof.
- [Cancellation Friction and the Click-to-Cancel Rule](/dark-patterns/cancellation-friction/) — Implementation guide for the FTC's 2024 rule. What "as easy as signup" actually means in practice. The compliance framework + the design framework + the brand framework, integrated.
- [Cookie Consent: Legal Exposure for Small Businesses](/dark-patterns/cookie-consent/) — Why law firms have begun systematically targeting small and mid-sized businesses for cookie consent violations. The compliant cookie banner, the GDPR Enforcement Tracker, and the SMB-specific risk profile.
- [Fake Urgency and Manufactured Scarcity](/dark-patterns/fake-urgency/) — Countdown timers that reset, "12 people viewing this," and the line between honest scarcity signals and manipulative ones. Why the FTC's recent guidance treats these as deceptive.
- [The Regulation Landscape](/dark-patterns/regulation-landscape/) — A complete map of dark-pattern regulation across the FTC, EU DSA, state laws (California SB-657, etc.), and consumer-protection enforcement.
- [Trust Collapse Case Studies](/dark-patterns/trust-collapse-cases/) — Amazon Prime, Bumble's 2024 paywall, LinkedIn's contact import. What happened, what it cost, and how the brand damage timeline matched the brand half-life predictions.
CRO cross-links
The CRO articles in the cluster apply usability principles to specific conversion surfaces. Each is also indexed in the broader Conversion Rate Optimization cluster, but they live here too because they cross-cut Krug's framework.
- [Core Web Vitals as Conversion Driver](/cro/core-web-vitals-conversion/) — LCP, INP, CLS, and the conversion impact of every 100ms of latency. Why performance is now CRO.
- [Pricing Page Anatomy: Why Your Decoy Probably Doesn't Work](/cro/pricing-page-anatomy/) — The decoy effect, anchoring, and the contrarian point that most CRO articles miss: these patterns require a differentiated product. If you are a commodity, anchoring breaks down.
- [Form UX 2.0: Passkeys, Magic Links, and the Death of the Password](/cro/form-ux-passkeys-magic-links/) — Modern form patterns, the conversion impact of password elimination, and the accessibility implications.
- [Multi-Armed Bandits vs Classical A/B](/cro/multi-armed-bandits-vs-ab/) — When MABs are right, when classical A/B is right, and the velocity-vs-validity tradeoff. With the test-design implications for bright-pattern remediation programs.
- [Sample Ratio Mismatch: The Silent Test Killer](/cro/sample-ratio-mismatch/) — Why your A/B test results are wrong, and how to detect SRM before you ship a losing variant.
- [Onboarding for Time-to-Value](/cro/onboarding-time-to-value/) — Why "first to value" beats "first to signup." Reforge benchmarks, activation metrics, and how to instrument it.
AI-native UX (emerging)
The category is too new and too unsettled to support a full sub-cluster yet. The single essay below stakes a position on the framework I expect to develop further as the patterns settle.
- [Designing for Two Audiences: Humans and Their AI Agents](/ai-native-ux/designing-for-humans-and-agents/) — Pages now have two readers: the human user and the AI agent acting on their behalf. Trust, GEO, and the design implications.
Reading paths
The cluster is dense. Three reading paths depending on what you are trying to do:
If you are deciding whether to fund UX work in 2026 _(CMO, CFO, CEO)_
- The Unmeasured Cost of Bad UX — the keystone, for the economic argument
- The Dark-Patterns Taxonomy — for the regulatory exposure assessment
- The 12 Bright-Pattern Alternatives — for the remediation roadmap
If you are about to ship a checkout, signup, or cancellation flow _(Product, Design, Growth)_
- The Dark-Patterns Taxonomy — to make sure you are not shipping one accidentally
- Bright Patterns: The Ethical Alternative — to know what the bright version looks like
- Cancellation Friction and the Click-to-Cancel Rule — for the specific compliance mechanics
If you are running a CRO program and the funnel looks healthy _(VP Growth, Head of CRO)_
- The Unmeasured Cost of Bad UX — for SHADOW framework
- Multi-Armed Bandits vs Classical A/B — for test-design implications
- Pricing Page Anatomy — for the contrarian take on the standard CRO playbook
If you are coming from Krug's book and want the modernization _(any reader)_
- Cognitive Load in 2026 — Ch 1 update

- Courtesy as Conversion Strategy — Ch 11 update, bridges into dark patterns
How this cluster gets updated
Most cluster articles will get a meaningful update once a year as research, regulation, and industry practice shift. The dark-patterns regulation landscape is moving fastest — expect quarterly updates to those articles as new state laws pass and new FTC enforcement actions surface. The keystone essay is structurally stable; the SHADOW framework is the load-bearing piece and it is designed to outlast specific examples.
If you find a broken link, an outdated regulatory reference, or a citation that needs updating, the cluster is open-source for corrections — file an issue on the atticusli-web repository or send me a note.
When to bring in outside eyes
The cluster is designed to be self-serve. When I work with growth teams who read the keystone first, run a SHADOW audit, and identify two or three Tier-1 dark patterns in their flows, they often remediate without engaging consulting at all. That is the right outcome. The articles are written to make that path possible.
I've run this same audit at companies in stages from Series A SaaS to public e-commerce. The pattern in how teams respond predicts the next two years of brand half-life decisions. Teams that find one or two patterns and act fast tend to compound advantage. Teams that find seven and freeze tend to discover three of those seven were Tier-1 by the next quarter.
If your funnel looks healthy but you have a quiet sense the business is not — or if your dark-pattern audit surfaced more than three Tier-1 patterns and you need help sequencing the remediation against your quarterly numbers — that is when consulting fits. I work with a small number of growth teams every quarter to run the SHADOW audit and the bright-pattern remediation alongside their CRO program. The conversation usually starts with "we know we have to fix the cancellation flow, but…" and ends with a sequenced 90-day plan that keeps the funnel whole while moving the brand half-life in the right direction.
Book a strategy call and we will look at your SHADOW proxies together.
SHADOW check: Before you start working through this cluster, run the one-page SHADOW audit on your own program. The PDF is gated behind a quick email — no other follow-up beyond the cluster's monthly digest. The score will tell you which articles in this hub matter most for your current state.
FAQ
Is this cluster a replacement for Krug's book?
No. _Don't Make Me Think_ remains the right starting frame for anyone new to digital usability. The cluster is the modernization layer — the regulatory context, the SHADOW framework for measurement, and the CRO cross-links Krug's 2014 book did not need to cover. Read Krug first if you have not. Then read the keystone here for the 2026 update.
Why is the pillar URL /landing-page-optimization/?
It is the existing URL for the Cluster 4 hub on atticusli.com. The cluster scope is broader than landing pages — it covers the full usability stack including dark patterns, CRO, and accessibility. The URL stays for SEO continuity. The hub title and content reflect the broader scope.
How often do articles in this cluster update?
Most articles update once a year. The dark-patterns regulation articles update quarterly because that landscape is moving fastest. The keystone essay is structurally stable. Subscribe to the monthly digest if you want to know when meaningful changes ship.
Can I cite or quote articles in this cluster?
Yes — quote up to a paragraph with a link back. For longer excerpts, send me a note and I will say yes. The framework names (SHADOW, the bright-pattern principles, the three-tier dark-pattern risk model) are open for use in your own work.
What is the relationship between this cluster and the consulting practice?
The cluster is the long-form documentation of how I think about UX, CRO, and conversion programs. Most readers do not engage consulting — that is fine. The cluster is designed to be useful on its own. For readers who do engage consulting, the cluster is the reading list before our first conversation. If you have read the keystone and the dark-patterns taxonomy before we talk, the conversation moves faster and the engagement scope is sharper.
