Why we should worry about the recent decline of reading, according to science

Last year, various surveys, including reliable indicators, have highlighted a significant decline in reading habits over the past decades. The most striking evidence is not simply that people read less, but that their capacity for deep reading is weakening. According to OECD data, the proportion of 15-year-olds who fail to reach minimum reading proficiency has now risen to nearly one in four across advanced economies, with sharp declines in tasks requiring inference, evaluation, and integration of information across texts. In the United States, NAEP scores show that average reading performance among 13-year-olds has fallen to its lowest level in decades, reversing long-standing gains. Laboratory studies mirror these trends: experiments comparing print and screen reading consistently find that readers of digital texts score 10–30% lower on comprehension and recall, particularly for longer and conceptually demanding material. Eye-tracking and cognitive load research further indicates that frequent digital readers engage in more skimming, less rereading, and shallower semantic processing. Crucially, these effects are not confined to weaker readers. Even highly educated adults now report shorter attention spans for long-form text and greater mental fatigue when reading complex arguments, suggesting that the decline of reading reflects not a loss of literacy, but an erosion of the cognitive endurance and attentional discipline that deep reading uniquely develops. Not just children To make matters worse, various robust data indicators show that adults are spending less time reading, especially for pleasure. For instance: (1) A large time-use study analyzing diary data from over 236,000 Americans found that the share of adults who read for pleasure on an average day dropped from about 28% in 2003 to just 16% in 2023, a roughly 40% decline over two decades . (2) That same research showed a steady annual fall of about 3% per year in the prevalence of daily leisure reading among U.S. adults. (3) An earlier report by the World Economic Forum indicated average daily reading time in the U.S. declined from about 23 minutes per day in 2004 to around 16 minutes by 2019, even before the most recent decade’s drop. (4) In the U.S., fewer adults now report reading books for pleasure: about 48.5% of adults said they read at least one book in the past year in 2022, down from 54.6% in 2012. A real concern? Should this really concern us? Perhaps not. After all, reading is just one medium through which humans have ingested information and exercised their minds, including for deep thinking. For most of history, knowledge travelled orally rather than silently on the page. Ancient cultures relied on storytelling, poetry, and song to preserve and transmit complex ideas: Homer’s epics were memorized and performed long before they were written down; Greek philosophy unfolded through dialogue rather than textbooks; and entire moral, legal, and scientific traditions were passed across generations through ritualized speech, music, and debate. From this perspective, the book is a relatively recent cognitive technology, not an eternal prerequisite for intelligence (consider that Socrates and his fellow philosophers were concerned by...
