The ‘jam paradox’ describes the phenomenon whereby a very wide range of options can make it more difficult for consumers to make a decision and, paradoxically, lead to a reduced willingness to buy.
The term originates from a well-known study by Sheena Iyengar, which examined how different levels of choice affect purchasing behaviour.
In a classic experiment, customers were offered a jam stall with either a large or a small selection of varieties. The results showed that:
- A wider choice led to greater interest, but fewer actual purchases
- A smaller selection led to less interest, but significantly more sales
This behaviour can be explained by decision overload: the more options there are, the harder it becomes to make a decision, and the greater the likelihood of uncertainty or procrastination.
Typical effects of the jam paradox are:
- so-called „choice overload“ (overwhelm caused by having too many options)
- Fear of making decisions or procrastination
- Lower conversion rates despite high levels of attention
- Regret after making a decision („Should I have chosen something else?“)
This concept is highly relevant in practice for start-ups and businesses, particularly in product design and marketing.
Key implications are:
- When it comes to product variants, less is often more
- Clear positioning makes purchasing decisions easier
- Structured options improve conversion rates
- Reducing complexity increases user satisfaction
Examples of use:
- E-commerce: Limiting product filters or variants
- SaaS products: simplified pricing models
- Marketing: clear and focused communication of the offering
- UX design: intuitive and streamlined decision-making processes
The jam paradox shows that too much choice does not automatically lead to better outcomes; on the contrary, it can reduce the quality of decision-making and the likelihood of a purchase.
