Post-literacy debate

The post-literacy debate is the argument over whether mass screen adoption (television, then internet, then smartphones/social media) is driving a measurable civilizational decline in reading, cognition, and civic capacity — and, if decline is real, whether screens are the cause or merely correlated with deeper drivers such as education policy. The term “post-literate” (as distinct from illiterate) comes from James Marriott’s 2025 polemic The New Dark Ages: a society that can read but prefers video and audio, drifting from a written culture toward an oral one — more tribal, more forgetful, less able to sustain liberal democracy.¹

Marriott’s thesis and its structure

Marriott bundles at least eight separable claims into one “media theory of everything”: loss of literary heritage, social atomization, cultural simplification, cultural degeneration, loss of attentional agency, cognitive decline (PISA + reverse Flynn effect), political extremism/populism, and finally the end of democracy. Alexander Thompson’s review (the wiki’s entry point) argues this bundling is the book’s core methodological flaw: strong claims (screens crowd out socialization; public discourse has visibly coarsened) are welded to weak causal attributions (screens cause PISA decline, cause populism), and the weak links discredit the strong ones.²

Thompson’s sharpest structural observation is the elitism trap: Marriott refuses on principle to defend “elitist” intellectual standards (he explicitly sympathizes with the Arts Council’s warning against “terms like excellence”), so he cannot argue post-literacy is inherently bad. He is forced to route every aesthetic/moral objection through an empirical harm claim (IQ, PISA, democracy) — which makes the empirical claims carry more weight than they can bear, and leaves his prescriptions (“treat reading like exercise”) strangely weightless.³

The cognitive-decline evidence

Reverse Flynn effect is real but small and environmental

IQ scores rose ~3 points/decade through the 20th century (the Flynn effect) and have reversed in several Western countries since the 1990s. Bratsberg & Rogeberg (PNAS 2018), using Norwegian military-conscription register data across 30 male birth cohorts (1962–1991), show that both the rise and the reversal are fully recoverable from within-family variation — siblings born in different years track the cohort trend.⁴ This rules out the two then-prominent compositional explanations (dysgenic fertility, immigration) and establishes that the reversal is driven by environmental factors operating within families. Peak cohort: born ~1975 — after television was already ubiquitous in Norwegian homes, which sits awkwardly with a simple television-caused-decline story.

The cable-TV natural experiment: real effect, small magnitude

Marriott’s load-bearing empirical citation is Hernæs, Markussen & Røed (IZA DP 9645, 2016; published JHR 2019), which exploits the staggered, supply-driven rollout of cable television across Norwegian municipalities in the 1980s–90s as a natural experiment.⁵ Findings: one additional year of full cable coverage during childhood lowers young men’s ability scores by 0.53% of a standard deviation (≈0.08 IQ points) and reduces male high-school completion by ~0.3 percentage points; effects concentrate in preschool/elementary exposure and are consistent with TV crowding out reading (larger for boys). The authors themselves estimate the cable expansion explains only ~12% of the 1.9-point Norwegian IQ decline over the period — a real but modest effect, roughly half a year of schooling across 18 years of exposure.

PISA: decline is real, but the pattern doesn’t fit screens

The OECD’s PISA 2022 long-term-trends chapter documents that OECD-average reading and science trajectories peaked between PISA 2009–2012 and had been falling for a decade before COVID; math held flat 2003–2018 then dropped sharply 2018→2022 (−15 points, triple any previous change; reading −10).⁶ But the cross-country pattern is hostile to a screens-only explanation: over 2012–2022 only 29 of 63 countries/economies deteriorated in 2+ subjects while six improved in 2+; Singapore, Japan, Korea, and Chinese Taipei maintained or raised already-high performance; Colombia, Macao, Peru, and Qatar improved across all three subjects over their participation. US reading improved after 2012; England and Estonia roughly held steady after 2015 while neighbors declined. Smartphone diffusion is near-universal across these countries; their outcomes diverge.⁷⁸

Thompson’s alternative attribution: the countries that avoided PISA malaise (Estonia, England, East Asian systems) run more rigorous education systems — knowledge-rich curricula, direct instruction, systematic phonics — which their more progressive neighbors abandoned between 1975–1990. His warning: blaming phones exculpates education policy (“It wasn’t the fault of the curricula we stripped of knowledge, it was the phones!”). Note this counter-claim is itself contested — the “reading wars” literature disputes how much of England’s PISA/PIRLS performance is attributable to the phonics reforms specifically — so the wiki treats it as a live hypothesis, not settled fact.⁹

Where the stronger claims survive

• Time substitution and civic life. Screens crowd out in-person socialization; this is the best-supported harm and was made earlier and better in Putnam’s Bowling Alone. See trust-and-social-capital and attention-economy — where Allcott et al.’s deactivation experiments and Bursztyn et al.’s collective-trap result quantify the welfare structure of the trap.
• Coarsening of public discourse. The dumbing-down of political speech and broadcasting is hard to deny observationally, even if its causal weight from screens vs. institutional incentives is unsettled.
• Populism. Social media looks neither necessary nor sufficient: Iceland, Norway, Switzerland, Estonia, and Japan remain politically stable despite similar screen penetration; Thompson’s concrete prediction — current-form social media will not radically alter Norwegian/Icelandic/Swiss political discourse within two decades.¹⁰

Open questions

• If education systems dominate screen exposure in explaining PISA divergence, what is the relative weight of curriculum content vs. instruction method vs. tutoring culture?
• Does the reverse Flynn effect continue past the 1991 cohorts, and does it track screen-era cohorts more strongly than Bratsberg & Rogeberg’s window shows?
• Is the Anglosphere-specific youth mental-health decline a screen effect, an economic-stagnation effect (Thompson’s preferred alternative for Britain), or a reporting/culture effect?
• Can a cultural-elitist defense of reading be made without the empirical-harm scaffolding — and would it be more honest?
