Progressive Disclosure: From Training Wheels to Week-Long AI Agents

Substack · 3 months ago · 8

Progressive disclosure is an interaction design technique that presents essential features prominently while deferring specialized options to secondary layers, supported by 40 years of evidence showing novices learn faster and experts need only one additional click. Research from 1984 demonstrated that hiding advanced functions reduces beginner errors by approximately 25% and speeds learning, while modern applications of the pattern achieve an 80/20 split where most tasks complete at level 1. The pattern becomes increasingly important for AI agents and long-running processes, requiring careful data-driven decisions about what goes where, honest labeling, and strict adherence to two levels maximum to maintain usability and discoverability.
