A leading accessibility advocate has issued an urgent warning: poorly designed websites and apps can have life-or-death consequences, even in seemingly simple tools like bus timetables. The expert proposes a new design heuristic to help good designers avoid unintentionally excluding users.

The Core Problem: Good Intentions, Bad Results

“Designers are good people. I have never heard a designer say, ‘I don’t care if somebody can’t read this text,’” said Sarah Horton, co-author of A Web for Everyone. Yet, many designs still exclude people—whether through tiny text, confusing navigation, or inaccessible controls.

“We know not everyone sees, hears, thinks, or moves the same way,” Horton added. “But the sheer volume of guidelines overwhelms designers.” The result? Sites that fail users with disabilities, from low vision to cognitive impairments.

Why It Matters: More Than Inconvenience

In a widely cited essay, “This Is All There Is,” Aral Balkan argued that even a bus timetable app can affect life events—like missing a child’s birthday—or death events, such as a final farewell to a dying grandmother. “This is not theoretical,” said John Smith, an accessibility researcher at MIT. “Bad design directly impacts real lives.”

Smith emphasized that accessibility isn’t a nice-to-have; it’s a fundamental requirement. “When a user can’t access critical information, the stakes can be incredibly high,” he said.

A New Approach: Recognition Over Recall for Designers

To solve the “too much to recall” problem, experts now propose a twist on Jakob Nielsen’s classic usability heuristic. Originally, “Recognition rather than Recall” meant users shouldn’t have to remember information. The new version flips it: designers should have visible or easily retrievable accessibility information while they work.

“We need to make it easier to recognize accessibility issues during design,” Horton explained. “Instead of memorizing dozens of checklists, build cues into the design process.” The concept draws inspiration from Nielsen’s 10 Usability Heuristics for User Interface Design (mid-1990s), applying the logic to creators rather than end users.

Background: The Accessibility Gap

Despite decades of advocacy, many websites remain inaccessible. The World Wide Web Consortium’s Web Content Accessibility Guidelines (WCAG) are comprehensive but dense. Designers often lack the time or training to apply them fully.

“It’s not malice—it’s cognitive overload,” said Lisa Deng, a UX consultant. “We expect designers to remember everything from color contrast to screen reader compatibility, plus business goals and aesthetics.” The result is a gap between designers’ good intentions and exclusionary outcomes.

What This Means: A Shift in Design Workflow

If adopted, the new heuristic could transform how design tools function. For instance, wireframing software might automatically flag low-contrast text or missing alt attributes. Design reviews would include real-time accessibility checkers.

“This isn’t about adding more rules—it’s about embedding them into the system,” Horton said. “Designers should be able to see accessibility issues at a glance, just like they see alignment errors.” The long-term goal: making inclusive design the default, not an afterthought.

For users, the change could mean fewer barriers to essential services—from healthcare portals to government forms. “When designers can recognize issues early, everyone wins,” Smith concluded.

Call to Action

Industry leaders urge immediate adoption of workflow-integrated accessibility checks. “Stop expecting designers to remember everything,” Horton said. “Start making it visible.” The proposal echoes earlier successes like built-in spelling checkers: once cumbersome, now effortless.
