This is a Lexicon entry: the mechanism, when it shows up, and the countermeasure. The full correction, with real-world cases and the audit prompt, hasn't been written yet.
Definition
The foundational distinction between two modes of thought: System 1 is fast, automatic, emotional, unconscious and effortless - it jumps to conclusions. System 2 is slow, deliberate, logical, effortful and conscious - it checks the work. Almost every cognitive bias in psychology can be traced to System 1 operating where System 2 should have been in charge.
When it shows up
Every waking moment where a decision forms before you notice you are deciding. Intuitive judgments, snap reactions, automatic routines. Any response that felt immediate.
Failure mode
System 1 produces an answer instantly and confidently; System 2 rarely activates to check unless deliberately prompted. Speed and confidence mask the lack of analysis. Errors made by System 1 are invisible to System 1.
Countermeasure
Any important judgment gets a five-second pause before commitment. The pause does not improve the answer directly but creates the gap where System 2 can engage.
