This study examines the necessary personality traits for Innovative Behavior at Work, using the Necessary Condition Analysis (NCA) methodology. Four studies were conducted, with a total of 1157 self-assessments based on the Big Five Inventory and of Innovative Work Behavior scales – encompassing narrow and exact replications. Our findings consistently highlight Openness and Extraversion as unanimous necessary personality traits for innovative behavior. Conscientiousness emerged as a necessary condition in 3 studies. Thanks to replicability approach, the research proposes thresholds for these traits, offering a nuanced understanding of their role in fostering corporate innovation. The study advances theory by shifting focus from correlation to necessity. It offers practical implications for HR and psychology practices in the assessment of future innovators. It also contributes methodologically by demonstrating replicability in NCA studies, paving the way for further exploration of personality and other innovation dynamics.
