德累斯顿工业大学的研究团队发现，人们倾向于不断重复之前做过的选择，即使存在更优的替代方案1。该研究分析了9项新的决策制定任务和6个已发表的数据集，涉及700多名参与者1。研究表明，单纯的重复行为会改变人们的偏好，使得熟悉的选择在新环境中仍被优先选择1。
研究负责人、认知计算神经科学教授Stefan Kiebel的团队在《Communications Psychology》期刊2025年第3卷第1期发表了这一成果1。首席作者Ben Wagner指出："令人惊讶的是，重复本身能够多么强烈地改变偏好"1。研究发现，许多看似"非理性"的偏好不一定主要源于人们基于其他价值观的选择，而是源于人们倾向于重复在特定背景中曾经偏好的行为1。更频繁被选择的选项不仅获得更高偏好，而且被评为更好的1。这一发现有助于解释许多日常生活中看似非理性的决策和习惯养成行为1。
Researchers at Dresden University of Technology have identified a fundamental pattern in human decision-making: people tend to repeat previous choices even when superior alternatives are available.1 The team analyzed nine new decision-making tasks and six published datasets involving over 700 participants to reach this conclusion.1
The research reveals that repetition itself can substantially reshape preferences.1 According to Ben Wagner, the study's lead author, "It is surprising how strongly repetition alone can change preferences."1 The findings suggest that many seemingly irrational preferences may not stem primarily from how people assign value based on other considerations, but rather from their tendency to repeat actions they previously favored in specific contexts.1 Notably, options selected more frequently were not only preferred more highly but were also rated as objectively better by participants.1
The study, led by Professor Stefan Kiebel of Dresden University of Technology's Department of Cognitive Computational Neuroscience, was published in Communications Psychology, Volume 3, Issue 1, 2025.1
