“This creates a different relationship with reading. It stops being a form of pleasurable immersion in another world and becomes more like dashing around a busy supermarket to grab what you need and then get out again. When this flip takes place—when our screen-reading contaminates our book-reading—we lose some of the pleasures of reading books themselves, and they become less appealing. It has other knock-on effects. Anne has conducted studies that split people into two groups, where one is given information in a printed book, and the other is given the same information on a screen. Everyone is then asked questions about what they just read. When you do this, you find that people understand and remember less of what they absorb on screens. There’s broad scientific evidence for this now, emerging from fifty-four studies, and she explained that it’s referred to as “screen inferiority.” This gap in understanding between books and screens is big enough that in elementary-school children, it’s the equivalent of two-thirds of a year’s growth in reading comprehension.”
