“The higher-quality materials are not available to them on or off line,” says Tara Brabazon, professor of media at the University of Brighton. She says that Google in itself is not the problem, but students' over-reliance “on any single platform or media [outlet]”. But US research suggests that academics may struggle to undo such behaviour. “It is too late to reverse-engineer deeply ingrained habits, notably an uncritical trust in branded search engines to deliver quick fixes.”

"Too late" to change habits? Bah. I don't believe it for a moment. People are amazingly capable of learning and changing.

There are ways for a teacher to make it unavoidably necessary for students to do their research from books and other "legitimate" sources. It's more work for the teacher and takes more time, so it's understandable if they're reluctant to do so, but that's not the same as it being impossible.
