Cognitive Biases & Systematic Errors

Level: advancedModel #22
thinking
Description

Human judgment follows predictable patterns that produce systematic errors. These aren't random mistakes—they're built into how System 1 processes information. Availability bias makes us overweight vivid examples. Confirmation bias makes us seek evidence that supports existing beliefs. Understanding these patterns helps recognize when intuition leads astray.

Applications
Check for availability bias by asking "am I overweighting this because it's vivid or recent?" The dramatic example that comes to mind easily might be the rare exception, not the typical case.
Combat confirmation bias with active disconfirmation. Don't ask "what confirms my belief?" Ask "what would prove me wrong?" Seek out smart people who disagree and understand their reasoning.
Be suspicious of strong intuitions in domains with poor feedback. You might feel certain about investing, parenting, or strategy, but these involve delayed, noisy feedback where biases flourish unchecked.
Remember that base rates usually matter more than specific details. The story feels compelling, but statistics are typically more reliable. Your intuition focuses on the narrative; good decisions focus on frequencies.

System 1 vs System 2 Thinking
The mind operates through two distinct systems. System 1 runs automatically and effortlessly—instant pattern recognition, emotional responses, and intuitive judgments. System 2 requires conscious effort—deliberate analysis, logical reasoning, and complex calculations. Most of life runs on System 1; System 2 steps in only when needed or surprised.

Mental Accounting & Reference Point Dependence
We treat identical amounts of money differently depending on mental categories—found money feels different than earned money, even though both have equal value. We evaluate outcomes relative to reference points rather than absolute terms—gaining $10 from $0 feels different than gaining $10 from $100. These mental accounting quirks create predictable irrationalities.
