The article of record as published may be found at https://doi.org/10.1007/s10869-019-09646-7Contributing to abusive supervision, creative leadership, and negative creativity research, we examine how and when leaders’ creative mindset relates to interpersonal aggression toward followers in the form of abusive supervision. Drawing upon moral disengagement theory, we theorize that leaders’ daily creative mindset positively relates to daily episodes of abusive supervision via state-based moral disengagement. Furthermore, we propose that trait-based moral disengagement moderates this indirect process such that low trait-based moral disengagement diminishes this effect. We found support for our hypotheses using a longitudinal study with a daily data collection over a 2-week period (Study 1) and an experimental study (Study 2). Our findings reveal the potential perils of leader creativity in leader-follower contexts and the importance of considering the moral disengagement process.This research was supported by grants funded by National Natural Science Foundation of China (Grant Nos. 71872190 and 71502179), Guangdong Province Higher Vocational Colleges and Schools Pearl River Scholar Funded Scheme (2018), and a Fulbright Scholarship sponsored by the U.S. government, awarded to Xin Qin, and grants by National Natural Science Foundation of China (Grant Nos. 71402164, 71732008, and 71772160), awarded to Song Wang
