CONCEPT
Sludge Audit
The systematic institutional review that classifies each instance of friction in a process as either purposeless waste or developmentally essential difficulty—eliminating the former and deliberately preserving the latter as AI tools remove both indiscriminately.
A sludge audit is the practical instrument that converts the distinction between
sludge and protective friction from a philosophical claim into a design decision. The distinction, developed by
Cass Sunstein and his collaborators, holds that friction is not a uniform phenomenon: some instances are pure waste, consuming time and attention while building nothing; others are developmentally essential, depositing the understanding on which all subsequent judgment depends. The problem is that the two kinds of friction are experientially identical in the moment of encounter—both feel like obstacles—and AI tools optimized for user satisfaction remove both indiscriminately, because the user prefers smoothness and the market delivers smoothness. The audit makes the distinction operationally actionable by requiring organizations, educational institutions, and tool designers to classify each point of friction by asking a single question: does this particular difficulty build something the person needs, or does it merely consume time and attention that could be better directed elsewhere? Implementation is sludge. Comprehension is protective. Execution is sludge.
