Uncertainty‐identity theory research shows that self‐uncertainty, directly or indirectly manipulated or measured, motivates group identification. Untested is an assumption that it is collective identity‐focused uncertainty that most directly motivates identification. Two studies tested this assumption. Study 1 (N = 140) measured self‐uncertainty relating to different aspects of self, with the expectation they would cluster into three distinct domains—individual, relational, collective self‐uncertainty. This expectation was supported. Study 2 (N = 382) manipulated uncertainty (low, high) and domain of self (individual, relational, collective) in a 2 × 3 design and measured identification. As predicted uncertainty strengthened identification (H1) and this was moderated by domain (H2)—it was only significant on collective self. Implications for self‐uncertainty fluidity and uncertainty reduction through group identification are discussed.

自我不确定性领域及其与群体认同的关系

不确定性身份理论研究表明，直接或间接操纵或测量的自我不确定性会激发群体认同。未经检验的假设是，以集体身份为中心的不确定性最直接地激发了认同。有两项研究检验了这一假设。研究1（N  = 140）测量了与自我不同方面有关的自我不确定性，并期望它们会分为三个不同的领域：个人，关系，集体自我不确定性。这一期望得到了支持。研究2（N = 382）在2×3设计中对不确定性（低，高）和自我领域（个人，关系，集体）进行了操纵，并进行了测量识别。正如预测的不确定性会增强识别（H1）一样，并通过领域（H2）加以缓和-它仅对集体自我具有重要意义。讨论了通过组识别对自我不确定性流动性和不确定性减少的影响。
