Once upon a time, a woman read an extremely convincing book called The Literacy Delusion. This book used the most up-to-date neurological and cognitive research to demonstrate that reading books was bad for you on every level. That the more books you read, the more unhappy you feel and the less effective you are at functioning in society.
The genius of this book was that its authors (a behavioral scientist and a journalist who met through a fellowship at MIT's Design Lab) used all the methodologies developed to test whether or not social media is bad, and they applied those methodologies to the act of reading books, resulting in the paradoxical finding that reading books was not just equally bad but that it was, in fact, quite a bit worse than TikTok and Instagram, precisely because books aren’t mere entertainment. Books are worse because they're more effective at changing people.
The Literacy Delusion demonstrated, using a large body of research, that book-reading tends to rob people of the ability to appreciate fine nuances.
