A new study from TU Dresden University of Technology suggests that past decisions may influence current choices more strongly than previously thought. The findings offer fresh insight into how people make everyday decisions, develop habits, and continue choosing familiar options. The study was published in the journal Communications Psychology.
Why people continue choosing familiar options
Why do people often return to familiar choices, even when better alternatives are available? A research team led by Stefan Kiebel, Professor of Cognitive and Computational Neuroscience at TU Dresden, examined how previous decisions shape future preferences.
The researchers analyzed nine newly collected decision-making tasks and six previously published datasets involving more than 700 participants. The study focused on how people learn the value of different options in specific situations and which choices they prefer when those options are later presented in new combinations.
“Our research shows that many seemingly irrational preferences do not primarily result from people storing values relative to one another. Instead, they may develop because people repeat behaviors they previously preferred in particular contexts,” explains lead author Dr. Ben Wagner. “This repeated behavior can cause certain options to remain preferred in new situations, even when equivalent or better alternatives are available.”
How past decisions influence future choices
The findings show that people have a strong tendency to repeat decisions they have made before, even when those choices are no longer optimal for the situation.
Rather than carefully comparing the advantages and disadvantages of every available option, people may rely on memories of their previous choices. This remembered action can serve as a mental shortcut, increasing the likelihood that they will make the same decision again.
“What is surprising is how strongly repetition alone can change preferences,” Wagner says. “Options that were selected more often were not only preferred more frequently but were also rated as better.”
Repetition can shape personal preferences
The results may help explain behaviors that appear illogical in everyday life. Repeated choices can influence shopping habits, daily routines, and other decision-making patterns, particularly when people continue selecting familiar options despite the availability of comparable or better alternatives.
The study also offers researchers a more realistic way to understand human decision-making. These insights could contribute to future research in psychology and behavioral science, as well as the design of environments where people regularly make important choices.
