This is an example of a myth that just won't die. The Skeptics Society (to give but one example) has been trying for years to put this nonsense to rest: https://www.skeptic.com/insight/the-myth-of-learning-styles/ I have even made multiple visits to my children's schools and tried to explain the actual research connected with pedagogy and communication but to little avail: https://www.psychologicalscience.org/journal…
I've heard that the commonly-debunked version of this is a totally misrepresented version of the original claim. The debunked one being that we only use 10% of our brain matter ever, while the original claim was something more like "at a given instant in time, only ~10% of your neurons are firing".
