The Interface Paradox – Part 4: Designing Protective Friction
·1433 words·7 mins
Examines nuclear launch protocols, financial circuit breakers, and deliberate two-step hazard confirmation as demonstrations that protective friction is a structural safety feature, not a design failure.
The Interface Paradox – Part 3: The Medical Interface Crisis
·1379 words·7 mins
Traces EHR interface design failures to measurable medication error rates, establishing that the medical interface crisis is a CRIP-equivalent phenomenon in clinical software design.
The Interface Paradox – Part 2: The Touchscreen Cockpit
·1529 words·8 mins
Documents aviation's glass cockpit transition and how digital interfaces increased IEAF in the mode-confusion regime, with accident data quantifying the cost of reducing electromechanical friction.
The Interface Paradox – Part 1: The Paradox of the Simple Action
·1627 words·8 mins
Uses TMI, Therac-25, and AF447 to establish that minimal input leading to maximal consequence is the signature failure mode of modern interface design, introducing the Interface Error Amplification Factor.
