Are we on the same page? Leader-follower value congruence as a boundary condition in the emergence of charismatic effects
通过三项实验检验了领导者-追随者价值观一致性在魅力信号与魅力效应关系中的调节作用，发现价值观一致时魅力信号更有效，不一致时可能产生反效果。
In the emergence of the charismatic effect, the leader–follower value congruence assumption posits that the charisma signal creates a charismatic effect for followers who have congruent values with the leader but may repel followers with incongruent values. Whereas this assumption is a central pillar of charisma signaling, it has not been causally tested. We theorize the charisma signal, leader–follower value congruence, and their interaction as predictors of the charismatic effect (i.e., perceived leader charisma, prototypicality, and effectiveness). In three preregistered experiments, we manipulate the charisma signal and communicated leader values by relying on video-recorded speeches and measure follower values beforehand. We operationalize leader–follower value congruence as the degree to which communicated leader values and measured follower values match. Study 1 showed mixed results for the leader–follower value congruence assumption, whereas Studies 2 and 3 – using polarized rhetoric – fully support it. We found some evidence that value congruence moderates the charisma signal–charismatic effect relationship, such that the relationship becomes stronger (weaker) with more value congruence (incongruence) in Studies 1 and 3 (but not in Study 2). Theoretical and practical implications as well as limitations are discussed.
