E-readers are convenient, but there are three reasons to lean toward paper books this summer. First, e-readers are screens, and the pull of everything else you could do on one makes it harder to stay immersed. Second, a large meta-analysis found people understand and remember slightly better on paper, especially with longer texts. Third, easy access to endless book samples makes it too tempting to jump ship rather than work through the slower parts, since reading, unlike TikTok, is about delayed gratification.
