This research explores perceptions of interpersonal influence in the form of flattery that occurs in a consumer retail setting. Across 4 experiments, results demonstrate empirical evidence of a sinister attribution error (Kramer, 1994), as consumer reactions to flattery were more negative than warranted by the situation. Results across 3 experiments demonstrated that there are 2 types of information processing occurring when consumers make trust judgments in response to flattery. Depending on when flattery occurs, consumers engage in either automatic or deliberative processing of information provided by the sales context. The final experiment further suggests that the automatic processing occurred through categorization based on social cues.
