Does Saying “Thanks a Lot” Make You Look Less Than? The Magnitude of Gratitude Shapes Perceptions of Relational Hierarchy

Gratitude expressions provide shared warmth benefits to both the thanker and the helper. Little work has explored how gratitude expressions shift how observers see these individuals on another important dimension: their relative rank. We consider how the magnitude of gratitude expressions shapes observers’ perceptions of the thanker’s and helper’s relative status and power. Seven studies find that thankers who expressed more, compared to less, intense gratitude than expected made their helpers seem relatively higher rank, though this pattern was inconsistent across metrics of gratitude in studies using real-world expressions. These effects emerged across a range of contexts and relationships. Mechanism analyses yielded several null results, while underscoring the role of perceptions of agency. Observers may make their inferences directly, based on intuiting the real association between a thanker’s gratitude and their helper’s power and status. Our findings demonstrate that gratitude signals rank relationships, qualifying current recommendations to express gratitude publicly.
