The Inmates Are Running the Asylum: Why High-Tech Products Drive Us Crazy and How to Restore the Sanity

Alan Cooper invented Visual Basic's interaction model and then spent the rest of his career arguing that engineers should not design the products they build. This book introduced personas as a design method — not the diluted marketing personas used today, but richly researched archetypes grounded in behavioral patterns. Cooper's core claim is that software is hostile to normal people because the people who build it optimize for their own mental models, and that design must be an independent discipline with authority in the development process. The book was published in 1999, when this was a genuinely controversial position in the industry, and Cooper fought the cultural war for design's seat at the table when almost no one else was fighting it. The organizational argument — that interaction design must happen before engineering begins — remains uncomfortable and largely unimplemented in most product teams.
