Five teardowns to start with
The biases
Browse by bias
Price
Price & attribute framing
The same price feels smaller in the right unit.
Social
Social proof
When unsure, we copy what people like us do.
Price
Zero-price effect
Free feels different from cheap, not just cheaper.
Social
Authority
We lean on experts and badges when we can't judge for ourselves.
Principle
Incentive (principle)
A reward for doing something changes what we do.
Anchoring
Reference price
A price feels cheap or dear only next to another price.
Time
Urgency (deadline effect)
A deadline makes acting now feel necessary.
Risk
Regret aversion (risk reversal)
We pick the option we're least likely to regret.
