Repeated choices can outweigh better options, new study shows
Researchers at Technische Universität Dresden discovered that simply repeating a decision can make familiar options seem more attractive than superior alternatives.
Scientists from Technische Universität Dresden investigated why individuals keep returning to familiar choices despite the presence of better alternatives. Analyzing nine fresh decision-making experiments together with six previously published data sets involving over 700 participants, the researchers identified a strong bias toward repeating past selections. Lead author Ben Wagner explained that this repetition acts as a mental shortcut, allowing the brain to favor previously chosen options without fresh comparison.
The study showed that items chosen more often were not only preferred but also judged as superior. Findings, published in Communications Psychology, suggest that habitual repetition shapes preferences in shopping, routines, and other daily decisions. The work offers a new framework for modeling human choice in psychology and behavioral design.
Why it matters
Understanding the power of repetition helps explain everyday habits and can improve how choices are presented in markets and public policy.
