Blind People Actually Have Higher IQs!A study published July 3, 2020 and conducted in South Africa and Austria shows that blind people have an IQ 14 points higher than average, and visually impaired people scored 3 points higher. The opposite result was found for verbal comprehension. Several other studies confirm these results.
Blindness, or more specifically, the way individuals react to blindness by compensating for a lack of external information causes blind people to increase their internal, working memory. Working memory has been shown to be critical for intelligence. This further underscores the theory that working memory, and therefore intelligence, can be modified.
