Seven Steps or Bust: The Cognitive Science Behind Good UX Design

A product design principle holds that no digital process should exceed seven steps, a limit rooted in Miller's Law — psychologist George Miller's 1956 finding that human working memory can hold roughly seven items at once. Every additional step in a digital flow adds cognitive load, and once users exhaust their mental bandwidth, they abandon the task entirely. Good UX is defined by invisibility: the user accomplishes their goal without consciously noticing the interface, while bad UX creates friction that drives users away and damages word-of-mouth. Designers are urged to challenge every step in a flow by asking what would break if it were removed — and to delete it if the answer is nothing. Amazon's now-legendary one-click purchase patent illustrates how eliminating even a single moment of hesitation can have outsized commercial impact.
