La bonne parole by Dominique Mehl, published in March 2003 by EdLM, is a French‑language paperback that explores the intersection of mass media, psychoanalysis, and public opinion. The author examines how psychological insights are employed in media discourse to shape societal attitudes and influence collective perception. Drawing on theories of influence and media effects, the book considers the ways in which psychologists engage with public forums, offering commentary that can affect opinion formation and cultural narratives. With 398 pages, the work provides a detailed look at the mechanisms through which expert voices are amplified in the public sphere, and it raises questions about the responsibility and impact of such interventions. Intended for readers interested in media studies, psychology, and communication, La bonne parole offers a thoughtful analysis of contemporary media practices and their psychological underpinnings.
