Cognitive debt is defined by reliance on external systems, namely LLMs , to replace the effort of cognitive processes. This “outsourcing” of hard thinking results in: diminished critical inquiry, increased vulnerability to manipulation, and decreased creativity1. It has been compared to a “technical debt of the midn”
A particular strain of cognitive debt occurs in vibe coded projects where the owner or team loses the plot of their project and feels “less confident”2 about adding features3. By abdicating to the LLM, the developers no longer understand why design decisions were made or how the system works together3.
