I'm not the executive that I used to be: Understanding causes and consequences of personality change in the upper echelons

Even as studies concerning the importance of executive personality traits continue to proliferate, there remains a need to integrate the burgeoning literature surrounding Upper Echelons Theory (UET) with mounting psycho-logical evidence that adult personalities change over time. Current models of executive personality largely stop short of modeling the capacity and consequence of leader personality change, threatening the validity and usefulness of UET research more broadly. We argue that some UET personality literature conflates personality change with other cognitive phenomena and, by so doing, falls victim to the 'jingle' fallacy. To clarify and expand the conversation concerning executive personality change, we detail what is known about adult per-sonality change and suggest opportunities for bridging the gap between UET and other disciplines. We discuss possible drivers of executive personality change, possible firm-level outcomes, and insight into how executive personality change will advance UET research. We also outline methodologies to capture the phenomenon.
