德累斯顿工业大学的研究团队发现，人们存在强烈的倾向去重复之前做过的选择，即使存在更好的选择也不例外[1]。该研究通过分析超过700名参与者在9项新收集决策任务和6个已发表数据集中的表现，揭示了这一看似非理性的行为模式背后的认知机制[1]。
研究表明，纯粹的重复行为可以改变人们的偏好判断[1]。被更频繁选中的选项不仅会被重新选择，而且会被参与者评为更优[1]。德累斯顿工业大学认知计算神经科学系教授Stefan Kiebel领导的团队表示，"被选择得更频繁的选项不仅被优先偏好，而且被评价为更好"[1]。这一发现表明，人们对熟悉选项的偏好会在新环境中持续存在，形成一种决策的惯性。该研究已发表在《通讯心理学》期刊上[1]。
A research team at Technische Universität Dresden has discovered that people systematically repeat their previous choices even when superior alternatives become available.[1] The study, which examined over 700 participants across 9 newly collected decision-making tasks and 6 published datasets, reveals how this behavioral pattern shapes preference formation.[1] According to first author Ben Wagner, "Options that were chosen more frequently were not only preferred, but also rated as better."[1]
The research, led by Professor Stefan Kiebel from the Department of Cognitive Computational Neuroscience at Technische Universität Dresden, demonstrates that mere repetition can fundamentally alter how people evaluate their choices.[1] Rather than being purely irrational, this decision-making tendency reflects an underlying cognitive mechanism where familiar options maintain their appeal even in new environments.[1] The findings were published in Communications Psychology in 2025.[1]
