Cognitive Biases Quiz

Can you spot 12 common thinking traps? From confirmation bias to sunk cost fallacy — this科普 quiz helps you recognize the cognitive biases that shape your everyday decisions.

What Are Cognitive Biases?

Cognitive biases are systematic patterns of deviation from normative rational judgment. Since Kahneman & Tversky's groundbreaking research in the 1970s, psychologists have identified over 100 distinct cognitive biases.

Why Do We Have Biases?

The human brain uses two thinking systems:

System 1: Fast, intuitive, automatic (drives ~95% of daily decisions)
System 2: Slow, rational, energy-intensive

Cognitive biases mostly arise from System 1 heuristics — mental shortcuts the brain uses to save energy. They're usually helpful, but can lead to systematic errors in specific situations.

How to Reduce Bias

1. Awareness — acknowledging your biases is the first step 2. Slow down — give System 2 time to engage 3. Seek disconfirming evidence — fight confirmation bias 4. Use checklists — systematize your decisions
