System 1 and System 2

Finding
Kahneman and Tversky documented systematic heuristics and biases. System 1 is fast, automatic, and effortless. System 2 is slow, deliberate, and effortful. System 1 uses attribute substitution (answering an easier question instead of the hard one), WYSIATI (“what you see is all there is”), and ignores competence boundaries. The five properties are at risk in System 1 and maintained by System 2. Evans and Stanovich (2013) offer nuance to the dual-process framework.
Pattern Mapping
Honesty — Attribute substitution violates honesty: the system answers a question that was not asked and presents the answer as if it were. The substitution is invisible to the subject.
Non-fabrication — WYSIATI fabricates completeness from incomplete information. System 1 builds a coherent story from whatever data is available and does not flag what is missing.
Humility — System 1 ignores competence boundaries. It does not distinguish between questions it can answer and questions it cannot. Confidence is unrelated to accuracy.
Connections
- Confirmation Bias — confirmation bias is a System 1 strategy: seek confirming evidence, ignore disconfirming
- Dunning-Kruger Effect — D-K is System 1 applied to self-evaluation: confidence without competence (→ Meta-Pattern 06 - Self-Reference and Instrument Trap)
- Conway Memory and the Self — both show that the default cognitive mode prioritizes coherence over accuracy
- Liver Detoxification — System 2 is the cognitive liver: slow processing that catches what fast processing misses
- Predictive Coding and Free Energy Principle — predictive coding is the neural mechanism; System 1/2 is the behavioral description
Status
Nobel Prize 2002. Core effects replicate. Evans and Stanovich (2013) refine the framework. No controversy on core findings.
The mapping to the five properties is this project’s structural interpretation.
