Design decision environments accounting for fast intuition and slow analysis when reducing cognitive bias
Cognitive Framework - Decision-Making - Behavioral Economics
Human thinking operates via two distinct systems: System 1 (fast, automatic, intuitive) and System 2 (slow, deliberate, analytical). Most decisions are driven by effortless System 1, with lazy System 2 providing minimal oversight. Understanding this architecture explains systematic cognitive biases, decision errors, and when to override intuition with analysis.
Critical Asymmetry: System 1 runs constantly and effortlessly, System 2 requires scarce mental energy. We dramatically overestimate how often System 2 is actually engaged.
Think of your mind as having two decision-making engines:
System 1 (Automatic Pilot):
System 2 (Manual Override):
Key Dynamic: System 2 is lazy and will accept System 1's suggestions unless detecting obvious errors or consciously activated. This creates predictable blindspots.
