Numerous studies have sought proof of whether people are genuinely honest by testing whether cognitive control mechanisms are recruited during honest and dishonest behaviors. The underlying assumption is: Deliberate behaviors require cognitive control to inhibit intuitive responses. However, cognitive control during honest and dishonest behaviors can be required for other reasons than deliberation. Across 58 neuroimaging studies (1,211 subjects), we investigated different forms of honest and dishonest behaviors and demonstrated that many brain regions previously implicated in dishonesty may reflect more general cognitive mechanisms. We argue that the motivational/volitional dimension is central to deliberation and provide evidence that motivated dishonest behaviors recruit the perigenual anterior cingulate cortex. This work questions the view that cognitive control is a hallmark of dishonesty.
许多研究通过测试认知控制机制是否在诚实和不诚实行为中被招募，来寻找证明人们是否真的诚实的证据。其基本假设是：有意识的行为需要认知控制来抑制直觉反应。然而，诚实和不诚实行为中的认知控制可能出于除了深思熟虑之外的其他原因而被需要。在 58 项神经影像学研究（1111 名受试者）中，我们研究了不同形式的诚实和不诚实行为，并证明了先前与不诚实行为相关的许多大脑区域可能反映了更普遍的认知机制。我们认为，动机/意志维度对于深思熟虑至关重要，并提供了证据表明，有动机的不诚实行为会招募扣带回前侧的中央旁回。这项工作质疑了认知控制是不诚实的标志的观点。
