Experts aren’t sure how the concept spread, but it might have had something to do with the self-esteem movement of the late ’80s and early ’90s. Everyone was special—so everyone must have a special learning style too. Teachers told students about it in grade school. “Teachers like to think that they can reach every student, even struggling students, just by tailoring their instruction to match each student’s preferred learning format,” says Abby Knoll, a Ph.D. student at Central Michigan University who has studied learning styles. (Students, meanwhile, like to blame their scholastic failures on their teacher’s failure to align their teaching style with the student’s learning style.)

Either way, “by the time we get students at college,” says Polly Husmann, a professor at Indiana University, “they’ve already been told ‘You’re a visual learner.’” Or aural, or what have you.

The thing is, they’re not. Or at least, a lot of evidence suggests that people aren’t really one certain kind of learner or another. In a study published last month in the journal Anatomical Sciences Education, Husmann and her colleagues had hundreds of students take the VARK questionnaire to determine what kind of learner they supposedly were. The survey then gave them some study strategies that seem like they would correlate with that learning style. Husmann found that not only did students not study in ways that seemed to reflect their learning style, but those who did tailor their studying to suit their style didn’t do any better on their tests.

Husmann thinks that the students had fallen into certain study habits, which, once formed, were too hard to break. Students seemed to be interested in their learning styles, but not enough to actually change their studying behavior based on them. And even if they had, it wouldn’t have mattered.

“I think as a purely reflective exercise, just to get you thinking about your study habits, [VARK] might have a benefit,” Husmann says. “But the way we’ve been categorizing these learning styles doesn’t seem to hold up.”

Another study published last year in the British Journal of Psychology found that students who preferred learning visually thought they would remember pictures better, and those who preferred learning verbally thought they’d remember words better. But those preferences had no correlation to which they actually remembered better later on—words or pictures. Essentially, all the “learning style” meant, in this case, was that the subjects liked words or pictures better, not that words or pictures worked better for their memories.

In other words, “there’s evidence that people do try to treat tasks in accordance with what they believe to be their learning style, but it doesn’t help them,” Daniel Willingham, a psychologist at the University of Virginia, told me. In 2015, he reviewed the literature on learning styles and concluded that “learning styles theories have not panned out.”
