Can There Ever Be Too Many Options? A Meta-Analytic Review of Choice Overload
Journal of Consumer Research · 2010
Summary
The study found a mean effect size close to zero, with substantial variation across conditions.
For your marketing
Possible founder application
Avoid blanket advice to remove pricing plans or features just to reduce option count. Define the decision task and test whether complexity, preference uncertainty or decision goals create friction for your own users.
Identify the decision users are struggling with before removing options. For a pricing page, you could test clearer differences between plans or a recommended starting point against the existing page. Measure the relevant completed decision and downstream fit. Fewer plans should be a hypothesis to test, not an automatic conclusion from this research.
Reported result
What the study found
The authors report a mean effect size close to zero, with substantial variation across conditions. The evidence did not support a general rule that larger assortments reliably cause overload.
Research question
What the authors investigated
Does offering more options reliably make people less likely to choose or less satisfied?
Design
A quantitative meta-analysis synthesized 63 conditions from 50 published and unpublished studies on choice-set size and choice overload.
Sample and setting
Cross-study synthesis of 63 experimental conditions from 50 published and unpublished studies, involving 5,036 participants; conditions covered varied choice tasks and products.
Scope and transfer
Limitations to keep in view
The pooled average does not show that choice size never matters; heterogeneous tasks and contexts can produce different effects. This is a 2010 synthesis of the literature available at that time, not the last word on choice architecture.
