Why the first version can mislead: The route adds avoidable effort between the user’s stated intention and completion. In this retail basket example, the obstacle is: “The visible action creates an account; the guest path is buried in unrelated copy.” Evidence should show whether the alternative remains usable and whether “Continue as guest” reaches the represented state. A viable alternative becomes materially harder to discover than the business-preferred account route.
What a fairer design does: Present guest and account routes together with clear consequences and comparable interaction effort.

Review questions (3)
How many steps, waits and channel changes separate “Create account” from the completed retail basket outcome?
Capture every peer option, its default state and visual prominence; do those states support “The options address the same decision”?
Measure the same task through the clearest available route: does the effort difference persist once “Different actions with genuinely different complexity” is accounted for?

Complete pattern context
How this example relates to Obstructed alternative
A relevant alternative within the current decision is hidden, blocked or made materially harder than the business-favoured action. The label describes a recurring design mechanism; whether a particular implementation is harmful or unlawful depends on the complete journey, audience, evidence and rules within scope.
The full guide explains inclusion and exclusion criteria, harms, fair design principles, evidence questions and the relevant EU legal information layers. The example page isolates one scenario so it can be shared and discussed without reproducing the complete library on one page.
A fictional platform labels a control “Delete account”, but the confirmation only hides the profile and leaves data and reactivation available indefinitely.
A fictional retailer places account deletion behind six help pages and requires a support ticket containing an order number even for users who never ordered.
