It has been proposed that information sharing, which is a ubiquitous and consequential behavior, plays a critical role in cultivating and maintaining a sense of shared reality. Across three studies, we test this theory by investigating whether or not people are especially likely to share information that they believe will be interpreted similarly by others in their social circles. Using neuroimaging data collected while people who live in the same residential community viewed brief film clips, we find that more similar neural responses across participants is associated with a greater likelihood to share content. We then test this relationship using two behavioral studies and find (1) that people are particularly likely to share content that they believe others in their social circles will interpret similarly and (2) that perceived similarity with others leads to increased sharing likelihood. In concert, our findings support the idea that people are driven to share information to create and reinforce shared understanding, which is critical to social connection.
有人提出，信息共享作为一种普遍存在且具有重要影响的行为，在培养和维持共享现实感方面起着关键作用。在三项研究中，我们通过调查人们是否特别倾向于分享他们认为社交圈子中的其他人会有相似解读的信息来检验这一理论。利用居住在同一社区的人们观看简短电影片段时收集的神经成像数据，我们发现参与者之间更相似的神经反应与分享内容的可能性更大相关。然后，我们通过两项行为研究来检验这种关系，发现：（1）人们特别倾向于分享他们认为社交圈子中的其他人会有相似解读的内容；（2）与他人的感知相似性会导致分享可能性增加。总之，我们的研究结果支持了这样一种观点，即人们被驱使去分享信息以创造和加强共享理解，这对社会联系至关重要。
