This lesson continues a segment from Yale's Overcoming Dyslexia course, addressing who dyslexia affects and how widely it appears across populations. The instructor lays out prevalence data and discusses how dyslexia cuts across gender, socioeconomic status, and intelligence level, countering common misconceptions that it is rare or tied to lower ability. The lesson builds on an earlier part of the same module, extending the discussion of incidence rates and the groups in which dyslexia is often underdiagnosed. Delivered as a short, focused segment rather than a full standalone talk, it functions as one building block in a structured course on the science and identification of dyslexia, aimed at helping viewers understand the condition's true scope before moving into diagnosis and intervention topics covered later in the course.
