686: Todd Libby on Deceptive Patterns

What It Covers

Todd Libby explains deceptive patterns in web design, covering five proposed WCAG 3.0 guidelines that address manipulative UX tactics like artificial time pressure, misleading wording, hidden preselections, and obstructive overlays that harm users financially and psychologically.

Key Questions Answered

• •Artificial Time Pressure: WCAG 3.0 distinguishes between essential timers (movie ticket checkout limits) and artificial timers (fake countdown clocks that reset on browser refresh). Artificial pressure creates false scarcity to manipulate purchasing decisions and violates proposed accessibility standards by exploiting cognitive vulnerabilities.
• •Misleading Wording: Double negatives and confusing language in opt-out flows disproportionately harm users with cognitive disabilities and learning differences. Buttons should state clear actions like "Unsubscribe" rather than "Don't not opt me out" to ensure users understand consequences before clicking, making interfaces testable and compliant.
• •Hidden Preselections: Trump 2020 campaign used pre-checked boxes with text about the radical left that enrolled donors in monthly recurring payments, costing supporters hundreds of thousands of dollars. WCAG 3.0 aims to prevent checkboxes that affect finances, privacy, or safety from being pre-selected or buried in complex text.
• •No Obstruction Rule: DoorDash covered delivery fee prices with tooltips on mobile, preventing informed decisions. The guideline requires overlays to be dismissible, movable, and never obstruct essential information needed for task completion, with particular protection for users with motor control limitations who cannot easily dismiss small close buttons.
• •Roach Motel Patterns: Amazon's seven-step cancellation process exemplifies patterns that trap users through exhausting multi-page flows. The guideline requires completion processes to avoid misinformation and unnecessary redirects, ensuring users can cancel subscriptions or services without navigating deliberately complex paths designed to increase abandonment rates.
