Carroll and Rosson: Paradox of the Active User

• Mark Springett recommended this one.
• It's from 1987 and is a book chapter in Interfacing Thought: Cognitive Aspects of HCI
• Mark says it's still relevant and I agree.
• Carroll and Rosson are talking about interface design.
• They note two major problems: the Production Paradox and the Assimilation Paradox
• These are a consequence of the Active User.
• Users are active, act, and have limited knowledge of the system.
• This causes a problem when the system is new (they don't know it), and as it continues to be used (they may not learn extra features).
