人们常常会忽视与他们坚定信念相矛盾的证据。然而，人们对控制这种行为的神经机制知之甚少。我们使用神经成像来研究在面对反证时维持信念的神经系统，向40名自由主义者提出与他们强烈持有的政治和非政治观点相矛盾的论点。对政治信仰的挑战增加了默认模式网络的活动，默认模式网络是一组与自我表达和脱离外部世界相关的相互联系的结构。具有更大信念阻力的试验表明，背内侧前额叶皮层的反应增加，眶额皮层的活动减少。我们还发现，当评估反证时，改变主意的参与者在杏仁核和杏仁核中显示的BOLD信号较少。这些结果突出了情绪在信念改变阻力中的作用，并提供了对信念维持、动机性推理和相关现象所涉及的神经系统的深入了解。
People often discount evidence that contradicts their firmly held beliefs. However, little is known about the neural mechanisms that govern this behavior. We used neuroimaging to investigate the neural systems involved in maintaining belief in the face of counterevidence, presenting 40 liberals with arguments that contradicted their strongly held political and non-political views. Challenges to political beliefs produced increased activity in the default mode network—a set of interconnected structures associated with self-representation and disengagement from the external world. Trials with greater belief resistance showed increased response in the dorsomedial prefrontal cortex and decreased activity in the orbitofrontal cortex. We also found that participants who changed their minds more showed less BOLD signal in the insula and the amygdala when evaluating counterevidence. These results highlight the role of emotion in belief-change resistance and offer insight into the neural systems involved in belief maintenance, motivated reasoning, and related phenomena.
