INSERM neuroscience research director whose "Screen Damage" became a bestseller questioning heavy screen use in children.
Michel Desmurget is a neuroscience research director at INSERM, France's national institute for health and medical research. His book — published in French as "La Fabrique du crétin digital" and in English as "Screen Damage" (2022) — became a bestseller in France, arguing that heavy recreational screen use in children is associated with slower cognitive and language development. Desmurget's research adds a French, INSERM-backed voice to the international body of work on screens and child development, and his book has been widely discussed among European researchers, educators, and policymakers weighing limits on children's screen use.

BOOKS
Screen Damage: The Dangers of Digital Media for Children (La Fabrique du crétin digital)
Michel Desmurget, a neuroscience research director at INSERM, published this essay in French in 2019 (English translation, Screen Damage, followed from Polity Press in 2022). Rather than presenting new experiments of his own, Desmurget synthesizes published research to argue that heavy recreational screen use — which he says now averages several hours a day across French children, from toddlers through teenagers — is associated with weaker language development, poorer concentration and memory, lower academic achievement, disrupted sleep, reduced physical activity, and higher rates of low mood and aggression among the heaviest users. The book became a bestseller in France, received a special mention from the 2019 Prix Femina essai jury, and was described by France Inter radio as a 'public health book.' TechKids includes it as a widely read synthesis of association-level evidence on screen time and child development, not as new clinical evidence of its own.
TV Lobotomie : La vérité scientifique sur les effets de la télévision
TV Lobotomie was Michel Desmurget's first popular-science book on media and children, published in 2011, eight years before his better-known La Fabrique du crétin digital. Writing as an INSERM neuroscience research director, Desmurget reviews published research on television viewing and argues that heavy childhood TV exposure is associated with weaker language and attention development, poorer school performance, and worse physical-health markers such as higher rates of childhood overweight, rather than being a neutral pastime. The book previewed the argument he would later extend to smartphones, tablets, and video games in his 2019 book: that the sheer volume of screen exposure, not any single device, is the variable most consistently associated with these outcomes in the literature he surveys. TechKids includes it as the origin point of Desmurget's screen-time advocacy, predating his more widely read later work.
Faites-les lire ! Pour en finir avec le crétin digital
Faites-les lire! is Michel Desmurget's 2023 follow-up to La Fabrique du crétin digital, shifting from diagnosis to a proposed remedy: recreational reading. Across a 416-page essay, the INSERM neuroscience research director argues that pleasure reading is associated with stronger language skills, creativity, sustained attention, writing ability, and academic performance than other leisure activities, including screen-based ones, and that this gap has practical stakes as French children's voluntary reading has declined. He distinguishes decoding text from genuine comprehension and argues family reading habits shape whether children read for pleasure at all. The book closes with concrete strategies for parents, teachers, and librarians to rebuild reading habits. TechKids includes it as Desmurget's own proposed counter-measure to the harms he associates with heavy screen use in his earlier books, giving the library a paired 'problem/response' framing from the same author.
VIDEOS
Le temps passé par les enfants devant les écrans est « hors normes, extravagant » (France Inter grand entretien)
Two months after La Fabrique du crétin digital was published, Michel Desmurget was the morning grand entretien guest on France Inter, France's most-listened-to public radio station, interviewed by Nicolas Demorand. The INSERM neuroscience research director calls the time French children now spend on recreational screens « hors normes, extravagant » — outside all norms — and walks through the associations his book draws from published research: heavier recreational screen use tracking with weaker language development, poorer concentration, lower school results, and shorter sleep. Desmurget's deliberately alarmist framing — a « fabrique du crétin » — is his own rhetoric, not a clinical finding, and the interview shows how that framing carried his synthesis into France's mainstream morning-news audience. TechKids includes it as the flagship French broadcast interview for the book, alongside the print interviews the same autumn.
¿Cómo afectan las pantallas a tus hijos? (BBVA Aprendemos Juntos talk)
In this long-form filmed talk for Aprendemos Juntos 2030 — the Spanish-language education series produced by BBVA and distributed with El País — Michel Desmurget speaks for close to ninety minutes on how screens relate to children's development. The INSERM neuroscience research director argues that heavy recreational screen use is associated with weaker language, shorter attention, and disrupted sleep in children; contends that app and platform design is engineered to keep young users engaged; and dismisses the « digital natives » idea as a myth unsupported by the studies he reviews. He closes with his standing recommendations: little or no screen time in the early years, firm daily limits afterward, and reading as the leisure habit he says is most consistently associated with stronger cognitive and emotional development. TechKids includes it as his major Spanish-language talk, extending his French argument to a global audience.
Le livre, seul « antidote » face aux écrans (France Inter grand entretien)
Two days after Faites-les lire! was published, Michel Desmurget returned to France Inter's weekend grand entretien, interviewed by Marion L'Hour and Ali Baddou. Where his 2019 appearance pressed the case that heavy recreational screen use is associated with weaker language, attention, and school outcomes, this interview argues the response: the INSERM neuroscience research director presents pleasure reading as the one everyday habit he says the literature most consistently associates with stronger language, concentration, general knowledge, and empathy in children — the « antidote », in his own deliberately pointed word, to the screen habits he criticizes. He urges parents to read aloud early, keep books visible at home, and defend reading time against recreational screen time. TechKids includes it as the broadcast companion to the Faites-les lire! entry: the same author moving from diagnosis to remedy.
STUDIES
« El consumo digital exacerbado devora todo lo emocional y lo cognitivo de nuestra humanidad » (La Nación interview)
This long interview by Hugo Alconada Mon, one of Argentina's best-known investigative journalists, ran in La Nación as Michel Desmurget's book reached Spanish-language readers in late 2020. Desmurget repeats his most provocative contention — that today's « digital natives » may be the first children to test lower on IQ than their parents — and lists the outcomes he says the research literature most consistently associates with heavy recreational screen use: slower language development, disrupted sleep, weaker concentration, lower school results, and higher risk of excess weight. He frames the cumulative exposure in school-time terms: by his estimate, the hours a child spends on recreational screens between ages two and eighteen rival roughly thirty school years' worth of classroom time. The IQ-reversal claim is Desmurget's own reading of Flynn-effect data, contested by other researchers; TechKids relays it as his, not as settled science.
« C'est l'ensemble de notre humanité qui est impacté par les écrans » (Millénaire 3 interview)
Millénaire 3, the foresight publication of the Métropole de Lyon — the public authority of Desmurget's own home region, where his INSERM lab (Institut des sciences cognitives Marc Jeannerod) is based — published this extended interview by Cédric Polère in April 2024. Desmurget restates his synthesis in civic terms: heavy recreational screen use in children is, in the research he reviews, associated with weaker language, concentration, and school achievement, and he argues the erosion runs beyond test scores to empathy, attention, and shared culture — « l'ensemble de notre humanité ». He connects declining reading skill among French school-leavers to civic vulnerability, contending that citizens who read poorly are easier targets for misinformation, and again offers reading as the counter-habit. TechKids includes it as a rare local-government-published interview, showing his argument entering French public-policy discussion, not just media debate.
Effects on Children's Cognitive Development of Chronic Exposure to Screens
This 2012 journal article, co-written by pediatrician B. Harlé and INSERM neuroscience research director Michel Desmurget, is Desmurget's own peer-reviewed publication most directly on this library's subject (his other journal output is almost entirely on unrelated motor-control neuroscience). Published in the French pediatrics journal Archives de Pédiatrie, it reviews existing studies on rising screen time from televisions, video games, smartphones, and computers, concluding that the literature consistently links chronic heavy exposure with weaker academic achievement, slower language development, reduced attention, poorer sleep, and higher aggression in children and teens. The authors frame under-recognition of the issue among clinicians as a gap and call it a public-health concern that primary-care physicians should address by counseling families on prevention. TechKids includes it as the one peer-reviewed article Desmurget has personally co-authored on screens and child development, distinct from his popular books.
'Nativos digitales': los niños con un coeficiente intelectual más bajo que sus padres
This 2020 feature in El Diario NY, a Spanish-language New York newspaper, is built around an interview with Michel Desmurget about the Spanish edition of his book on children's screen use. Desmurget contends that today's most screen-exposed generation of children is on track to test with lower IQ scores than their parents' generation — a reversal, in his framing, of the historical post-war rise in measured IQ known as the Flynn effect — and cites studies he discusses in his book associating heavier gaming and device use with lower grades, weaker memory retention, and shorter attention spans. The piece also relays his recommendation of no screens before roughly age six and strict daily limits afterward. TechKids includes this as a rare example of Desmurget's book and claims reaching a U.S. Spanish-language audience directly through interview coverage, distinct from his own written work.
