It's not a hunch. It's not nostalgia. It's been measured across dozens of peer-reviewed studies, tens of thousands of students, and more than two decades of comparative research — and the finding is consistent: students comprehend and retain information better when they read it on paper than when they read it on a screen.
Researchers call it the "screen inferiority effect." And it's not subtle.

Screen reading rewires how students process information. Print readers slow down. They re-read difficult passages. They annotate. They stop. The same student, with the same content, reads differently depending on the medium — and performs differently on what comes after.
The effect is stronger for students who need it most. For students with learning differences — dyslexia, ADHD, processing disorders, working memory challenges — the comprehension loss from screen reading isn't marginal. It's significant. Well-formatted printed materials, with appropriate font size, line spacing, color contrast, and visual organization, are among the most effective interventions available.
This is what SumnerOne brings to an education partnership that no print vendor alone can offer: not just the capability to produce these materials, but the understanding of why they matter.
