Priceless: The Myth of Fair Value (and How to Take Advantage of It)
William Poundstone · amazon.com Paid Beginner
The foundational text on why customers judge price relative to context, not in absolute terms - the psychology behind every charm price, anchor and bundle you'll ever run. Dense with Kahneman-Tversky-backed research but written for a general reader.
- 'Coherent arbitrariness': people anchor on an arbitrary first number and judge everything after relative to it.
- A price can feel like a bargain or a rip-off purely based on framing, not the number itself.
- Charm pricing, decoy pricing and reference pricing all exploit the same underlying bias.
