Comment savoir ce qu'il faut croire ? | Paula Slier | TEDxUniversity of Johannesburg

Paula Slier, correspondante de guerre qui couvre depuis plus de vingt ans des zones de conflit comme Gaza, la Syrie, le Liban, l'Afghanistan, l'Irak, l'Ukraine et la Libye, s'interroge sur la manière dont l'information façonne nos convictions. S'appuyant sur son expérience des zones de guerre et sur l'environnement informationnel numérique actuel, elle examine comment les algorithmes, l'indignation, les réactions émotionnelles et la manipulation narrative influencent la vie quotidienne. Son argument central est que l'intelligence seule ne protège pas de la manipulation, car les personnes sont les plus vulnérables lorsque émotion, peur, espoir, appartenance et identité se croisent.

• Leçons sur la propagande tirées des zones de conflit
• Comment les algorithmes et l'indignation influencent les croyances
• Pourquoi émotion et identité accroissent la vulnérabilité

For more than two decades, Paula has reported from some of the world’s most dangerous conflict zones - Gaza, Syria, Lebanon, Afghanistan, Iraq, Ukraine, Libya and beyond - where information can be as powerful as weapons themselves. In war zones, survival depends on understanding narratives: propaganda, emotional triggering, fear, identity, and the stories people are persuaded to believe. For years, she believed information warfare belonged mainly to politics, governments, extremist groups, and digital platforms. This talk explores what happens when the battlefield moves beyond geography and politics and into everyday human experience. Drawing on lessons from physical war zones and today’s digital information environment, it examines how algorithms, outrage, emotional activation, and narrative manipulation increasingly blur the boundaries between public warfare and private vulnerability. At its core, this talk argues that intelligence alone does not protect us from manipulation. Human beings are most vulnerable when emotion, hope, fear, belonging, and identity intersect.
