In the world of television, the US medical drama House captivated audiences with its central character, the irascible and ill-tempered Dr Gregory House, portrayed by Hugh Laurie of The Night Manager fame. While such grumpy doctors might seem purely fictional, new research suggests that their abrasive approach could hold real-world persuasive power when addressing patients, a phenomenon scientists have dubbed the 'Dr House effect'.
Unpacking the 'Dr House Effect' in Persuasion
Researchers from Ispa – Instituto Universitario in Lisbon conducted a series of experiments to explore whether the unexpected rudeness of experts, akin to Dr House's bedside manner, might encourage people to pay closer attention to their messages. In the hit series, which aired for eight seasons until 2012, Dr House is often proven correct in his diagnoses despite his impolite and abrasive interactions with patients. For instance, when a short woman asks if he is high, he retorts, 'Higher than you!' or when a patient questions his rudeness, he bluntly replies, 'Yes. Don't think you are special!'
Experimental Insights into Expert Communication
To test this theory in a realistic setting, the Portuguese team designed experiments involving nearly 200 participants. In one part of the study, health information was delivered by either a dermatologist or a mother, using either a warm, polite tone or a cold, arrogant voice. The results were striking: when the speaker was identified as a dermatologist, participants found the rude delivery more persuasive than the polite one. Conversely, the mother was deemed more persuasive when she communicated politely.
Writing in the PsyCh Journal, the researchers explained, 'This pattern supports the Dr House effect, indicating a detrimental effect of politeness when combined with expertise, in contrast to impoliteness.' They theorise that unexpected behaviour, such as rudeness from an expert, captures attention more effectively, leading to heightened focus on the message being conveyed.
Implications for Real-World Interactions
This research challenges conventional wisdom about communication, suggesting that in certain contexts, like medical or expert advice, a gruff demeanour might enhance credibility and influence. However, it is crucial to note that this effect is context-dependent; for non-experts, such as the mother in the study, politeness remains key to persuasion. The findings highlight the complex dynamics of human interaction, where expertise and delivery style intersect to shape perceptions and outcomes.
