What Korea argues about when it argues about literacy
A country with near-universal basic literacy has spent years worrying that its readers no longer understand what they read.
The Korean literacy debate tends to arrive as a viral incident. In 2022 a webtoon platform posted an apology using the phrase simsimhan sagwa — a formal expression meaning a deeply felt apology — and a portion of readers took simsimhan for its homophone meaning bored, and objected that the company was apologizing casually. Two years earlier the word saheul, meaning three days, trended after readers took it to mean four, misled by its resemblance to the number four. Each episode produced the same cycle: mockery, alarmed commentary about a generation that cannot read, and a counter-argument that a single unfamiliar Sino-Korean word proves nothing.
The counter-argument has the stronger data behind it, at least on basic literacy. Korea’s adult illiteracy rate is very low; the education ministry’s periodic national survey of adult literacy has found the small share of adults functioning below an elementary reading level concentrated overwhelmingly among the very old, a legacy of interrupted schooling rather than a feature of current education. Fifteen-year-olds have placed near the top of the OECD’s PISA reading assessments for two decades, including in the 2022 round. By the ordinary international measures, Korean schools teach reading well.
Yet the anxiety is not baseless, and the more careful evidence points somewhere more specific than decline. In the OECD’s analysis of the 2018 PISA reading data, Korean students performed conspicuously poorly on tasks requiring them to distinguish a statement of fact from a statement of opinion — roughly a quarter succeeded, against an OECD average near half. That is not a deficit in decoding words. It is a deficit in doing something with them: evaluating a source, holding a claim at arm’s length, reading a text against its own framing. The OECD’s second cycle of its adult skills survey, published in 2024, likewise placed Korean adults at or slightly below the average of participating countries in literacy, with a notably steep falloff by age.
Those two findings together suggest the real subject of the argument. Korea did not lose basic literacy; it developed an educational culture optimized for extracting the correct answer from a passage under time pressure, which is what its examinations reward. The Korean SAT’s reading section is famously demanding, but it demands speed and precision on a closed question, not the sustained, argumentative engagement that the word literacy carries in the phrase deep reading. Vocabulary compounds the problem, because a large share of formal Korean vocabulary is Sino-Korean, and the retreat of Chinese character instruction from the curriculum removed a scaffolding that once made unfamiliar compound words guessable rather than opaque.
Media habits do the rest. Korea has among the world’s highest smartphone penetration and reading has migrated accordingly — to messenger threads, to comment sections, to webtoons that are scrolled rather than paged, to short-form video where text appears as captions. That mode of reading is genuinely skilled, but it trains scanning, pattern-matching and rapid judgment rather than the slow tolerance of ambiguity that a long argument requires. Teacher surveys through the early 2020s reported classroom experience consistent with this: students who read fluently but struggle with a dense paragraph or a text that does not announce its conclusion in the first line.
The policy response has been broad and somewhat unfocused: literacy diagnostics in early grades, a growing digital-literacy strand in the national curriculum, remedial programmes for students who fall behind in basic reading, and school library and reading-education initiatives. What remains unsettled is the definition. If literacy means recognizing words, Korea has essentially solved it. If it means the capacity to read a contested claim and locate its weak point, then no country has solved it, and the viral vocabulary incidents that keep triggering the debate are the least informative evidence available about how well Korea is doing.
