Although the effects of openness to experience (OTE) on individual creativity are well-established, research on how such effects unfold in a team context is scarce. Drawing on theories of group norms and uncertainty reduction, we argue that team mean OTE leads to a climate of team psychological safety which, in turn, facilitates team creativity. We test our hypothesis over three independent studies, the first comprising 35 business student project teams, the second based on 28 professional teams from the automotive industry, both conducted in the United Kingdom, and the third comprising 24 healthcare teams in Portugal. As predicted, across all three studies, team mean OTE was positively associated with team creativity via the affective emergent state of team psychological safety. Furthermore, the mediating role of team psychological safety remained significant even when accounting for team OTE variance, alternative motivational and cognitive emergent states, namely team promotion focus (studies 1 and 2) and team exploration climate (study 3), as well as empowering leadership (study 3). Finally, in study 3, we examined the differential impact of the two major facets of OTE, intellect, and openness, and found that intellect, but not openness, was responsible for driving the indirect effects. Further analysis did not support alternative perspectives concerning team OTE variance or the interaction between mean and variance. Our findings not only contribute to theoretical understanding regarding the relationship between team personality composition, specifically OTE, and team creativity but also provide much-needed insight into how such effects unfold. We delineate several practical implications for team design and development.

开放、安全感和创造力：团队的角色意味着开放的体验在团队心理安全和团队创造力的出现中

尽管体验开放性 (OTE) 对个人创造力的影响已得到充分证实，但关于这种影响如何在团队环境中发挥作用的研究却很少。借鉴群体规范和不确定性减少的理论，我们认为团队平均 OTE 会带来团队心理安全的氛围，进而促进团队创造力。我们通过三项独立研究检验了我们的假设，第一项由 35 个商科学生项目团队组成，第二项基于来自汽车行业的 28 个专业团队，均在英国进行，第三项由葡萄牙的 24 个医疗团队组成。正如预测的那样，在所有三项研究中，团队平均 OTE 通过团队心理安全的情感紧急状态与团队创造力呈正相关。此外，即使考虑了团队 OTE 方差、替代动机和认知紧急状态，即团队晋升焦点（研究 1 和 2）和团队探索氛围（研究 3）以及授权领导，团队心理安全的中介作用仍然很重要（研究 3）。最后，在研究 3 中，我们研究了 OTE 的两个主要方面（智力和开放性）的不同影响，发现智力（而不是开放性）负责驱动间接影响。进一步的分析不支持有关团队 OTE 方差或均值与方差之间的相互作用的其他观点。我们的研究结果不仅有助于从理论上理解团队个性构成（特别是 OTE）与团队创造力之间的关系，而且还提供了关于这种效应如何展开的急需的见解。我们描述了对团队设计和开发的几个实际影响。
