What is the famous jam study about choice overload?
Researchers found shoppers were more likely to buy jam when offered 6 options versus 24, suggesting too many choices reduced purchase likelihood.
Cognitive Biases
Choice Overload
A phenomenon where having too many options leads to anxiety, decision fatigue, and either no choice at all or a worse one.
Choice overload reduces decision quality and satisfaction by overwhelming cognitive capacity with excessive alternatives.
Core question
Can we reduce the number of options to the few that actually matter?
Example
An e-commerce site offering 47 subscription plans sees lower conversion than a competitor offering three clear tiers, because users cannot evaluate the differences.
How to apply
- 1.Curate options to a small set of meaningfully different choices.
- 2.Provide a clear default or recommendation.
- 3.Allow progressive filtering rather than showing everything at once.
Pitfalls
- ·Over-simplifying and removing options that serve distinct segments.
- ·Assuming fewer options always means better outcomes regardless of context.
- ·Hiding choices so deeply that informed users feel frustrated.
Questions

Simplify onboarding flows, pricing pages, and settings screens. Defaults and recommendations reduce cognitive load without removing flexibility.
