"As these first few weeks of the college semester begin, professors look out expectantly into grand lecture halls, where they see, rather than faces of students, the backs of open laptops," Timothy Snyder writes for The Christian Science Monitor. "The students, for their part, are looking intently at the laptop screens. … I teach at Yale, where lecturing is taken seriously - and in history, which boasts some of the best teachers. My ratings as a lecturer are consistently high. But even here, I would not have the attention of these very gifted students if I did not ban laptops and smart phones from my classroom. Part of the problem is that students are not paying attention at a given moment, part of the problem is that they often lack the ability to pay attention at all. … After university, students who could not concentrate in the classroom will become workers who cannot concentrate in the workplace."

"Right-wing beliefs are good for old people," they write.
