Neuromyths are understood as false concepts and beliefs about the brain and that have an application or impact, generally negative, in the educational field and, specifically, in the teaching and learning processes. We start from previous studies in which it has been analyzed how neuromyths persist in society and in educational personnel, both at the level of basic education, upper secondary education, university education and even in postgraduate studies, and from there we arrive at our own results. In this work, a survey was conducted among 290 participants (N = 290) to determine to what extent neuromyths prevail among the university student community (M = 42.8%), the general public (M = 27.5%) and teachers in Mexico (M = 29.7%). It was possible to integrate students and teachers from 20 states of the Mexican Republic, between 18 and 70 years of age. We found that there is basically a group of four neuromyths that capture the attention and belief of the participants (M = 91.05%) and that are related to the so-called “learning styles” (visual, auditory and kinesthetic) (M = 96.6%), as per the speculative anatomy of the brain: “the rational hemisphere and the creative hemisphere” (M = 90.7%) or the “triune brain” (M = 89%). Other neuromyths analyzed in this work were, for example, the belief in the effect of certain elements on neural performance: “the Mozart effect” (M = 74.5%); “sugar and hyperactivity” (M = 80.7%); “video games and violence” (M = 63.8%). Neuromyths prevail in Mexico not only among students, but also among the teaching community, regardless of educational level. Some neuromyths, such as that of differentiated learning pathways, or three brains in one, have already been “naturalized”, that is, “normal” is to consider them true by repetition, but without having been adequately analyzed.
