Why your brain keeps making the same decisions – even when better options exist
Why do we keep making the same choices even when better options are available? Researchers found that simply repeating a decision can reshape what we prefer, causing familiar choices to feel better than alternatives. Instead of weighing every option from scratch, the brain often remembers what it chose before and repeats it. That shortcut may help explain many everyday habits and seemingly…
A recent study from TUD Dresden University of Technology sheds light on why people frequently choose familiar options even when better alternatives are available. The research, led by Professor Stefan Kiebel, examined nine new decision-making tasks and six previously published datasets involving over 700 participants. The study reveals that people's preferences are often shaped by their past decisions rather than a careful comparison of options.
According to lead author Dr. Ben Wagner, people tend to repeat actions they once preferred in a specific context, leading to continued preference even when those choices are no longer optimal. This behavior, not a result of rational comparison, can create irrational preferences. The findings, published in Communications Psychology, demonstrate how repetition can override logical decision-making and influence everyday choices such as shopping habits.
The study may help psychologists and researchers better understand and model human decision-making, potentially improving the design of environments where choices are regularly made.
