<p>This study examines whether conceptual metaphors facilitate adaptive goal switching, particularly following the failure of a subgoal related to a superordinate goal. We tested the hypothesis that the “open-door” metaphor, which symbolizes transition and opportunity, encourages individuals to pursue alternative subgoals after failure. The research included a pilot study (<i>n</i> = 524), three preregistered studies (Study 1: <i>n</i> = 316; Study 2: <i>n</i> = 613; and Study 3: <i>n</i> = 335), and two supplemental studies (Study S1: <i>n</i> = 249; Study S2: <i>n</i> = 738). Exposure to the open-door metaphor, compared with control conditions and metaphors emphasizing closure, significantly increased engagement with new subgoals. Moreover, the metaphor shaped participants’ perception of goal switching as reengagement rather than disengagement, which mediated subsequent goal-directed behavior. These findings suggest that metaphors can serve as powerful cognitive tools for promoting flexible self-regulation. Implications for education, health promotion, and behavior change are discussed.</p>
