Verdict: DISPROVED Key Findings 3 out of 3 independent authoritative sources explicitly characterize the 10% claim as a myth, meeting the ≥ 3 threshold required for disproof. MIT McGovern Institute (academic): "the idea that we use 10 percent of our brain is 100 percent a myth" (B1, verified). Encyclopaedia Britannica (reference): "we use all of our brain all of the time" (B2, verified). Scientific American: "the 10-percent myth is one of those hopeful shibboleths that refuses to die" (B3, verified). No peer-reviewed neuroscience study was found that supports the 10% claim under any interpretation.
