In 1995, psychologist Barry Schwartz conducted a now-famous study involving jam. Shoppers exposed to a display of six varieties were far more likely to make a purchase than those presented with twenty-four. The finding was counterintuitive: more choice led to less action.
This phenomenon, which Schwartz later called the paradox of choice, has since been replicated across domains ranging from healthcare to retirement planning. The underlying mechanism appears to be cognitive overload: when the number of options exceeds our processing capacity, we experience anxiety rather than liberation.
What is more, the very act of choosing among many alternatives triggers a phenomenon known as anticipated regret. We do not merely choose — we imagine all the options we are forgoing. In a supermarket of six jams, we simply pick one. Faced with twenty-four, we begin to wonder whether we are making the right call.
Far from being a trivial concern, this insight has profound implications for public policy, product design, and personal well-being. Pension systems that offer dozens of investment options, for instance, see lower enrolment rates than those with a simple default.
The lesson is not that choice is bad — autonomy remains a fundamental human value. Rather, it is that the architecture of choice matters as much as choice itself. A well-designed set of options can empower; a poorly designed one can paralyse.
