Identity leadership is manifested via integrative complexity: Comment on Haslam et al. (2019).

Haslam, Reicher, and Van Bavel (2019) convincingly argued that experimenters in the Stanford Prison Experiment (SPE) influenced prisoners via identity-based communication. However, Haslam et al. focused on direct mechanisms of identity communication. In our comment, we discuss a less direct-but potentially equally important-communication mechanism by which leaders in the SPE may have influenced followers: integrative complexity. This consideration of integrative complexity not only bolsters the basic point of Haslam et al.'s article also provides new avenues for understanding the mechanisms by which leader identity processes work in cases like the SPE.
