Re-tell Lecture — Communication

Why stories persuade better than statistics Researchers in communication studies have consistently found that stories are more persuasive than statistics alone. When people hear a compelling narrative about a single individual, they engage emotionally: mirror neurons fire, oxytocin levels rise, and the listener mentally simulates the character's experience. Statistics, by contrast, are processed analytically and rarely produce an emotional response. A charity appeal featuring one named child raises more money than one citing millions in need, a phenomenon psychologists call the identifiable victim effect. This does not mean data is useless — it provides credibility — but the most effective communication combines both: a personal story that creates emotional engagement, followed by data that confirms the story is representative of a larger pattern. Advertisers, politicians, and public health campaigners have long understood this principle. Anti-smoking campaigns that feature individual stories of illness consistently outperform those that rely solely on mortality statistics, even when the statistical message is objectively more informative.

How body language shapes communication Research suggests that a significant proportion of human communication is nonverbal. Facial expressions, gestures, posture, eye contact, and tone of voice all convey meaning that can reinforce, contradict, or completely override spoken words. When someone says they are fine while avoiding eye contact and crossing their arms, listeners instinctively trust the body language over the words. This principle has important implications for public speaking, job interviews, and cross-cultural communication. Studies of political debates show that viewers who watch candidates with the sound off form impressions of competence and trustworthiness that predict election outcomes about as well as polls do. In professional settings, maintaining appropriate eye contact, using open gestures, and matching one's posture to the conversation's tone are consistently associated with higher ratings of credibility and likeability. However, nonverbal cues vary across cultures: direct eye contact signals honesty in many Western contexts but can be considered disrespectful in parts of East Asia and the Middle East. Effective communicators adapt their body language to the cultural expectations of their audience.

The spread of misinformation online A landmark study published in the journal Science in twenty eighteen analysed the spread of roughly one hundred and twenty-six thousand verified true and false news stories on a major social media platform over an eleven-year period. The findings were striking: false stories spread faster, reached more people, and penetrated deeper into networks than true stories in every category of information studied. The researchers found that false news was seventy per cent more likely to be shared than accurate news. Importantly, this difference was driven primarily by human behaviour rather than automated accounts. False stories tend to be more novel and more emotionally charged than true ones, triggering surprise and disgust — emotions that motivate sharing. The platform's algorithmic amplification of engaging content compounds the problem: content that generates reactions is shown to more users, regardless of its accuracy. Solutions proposed include media literacy education, labelling disputed content, and adjusting algorithms to prioritise accuracy alongside engagement. However, each approach involves trade-offs: labelling can backfire by drawing attention to false claims, and algorithmic changes may reduce platform revenue.
