“Blind people have a heightened sense of hearing or touch.”

The idea that blind individuals possess "super senses" is a common misconception, likely stemming from observations of their remarkable abilities to navigate and interpret the world without sight. When a person cannot see, their reliance on hearing and touch, and sometimes smell, becomes significantly greater, often leading to impressive demonstrations of sensory acuity that can appear almost supernatural (Review) to sighted observers. This perceived enhancement has been a recurring theme in popular culture, further cementing the myth in public consciousness.

While blind individuals do not inherently have more sensitive ears or fingertips than sighted people, scientific research has shown that their brains adapt in profound ways. This phenomenon, known as neuroplasticity, allows the brain to reorganize itself. Studies using MRI imaging have revealed that in people who are born blind or lose their sight early in life, the brain's occipital cortex, typically responsible for processing visual information, can be repurposed to enhance auditory and tactile processing. This "rewiring" leads to improved performance in tasks involving these remaining senses, such as discerning subtle differences in sounds or feeling intricate textures. These structural and functional changes result in a more efficient use of existing sensory input.

Therefore, the common belief in heightened senses is plausible because the functional outcome often resembles it. People commonly believe this myth because they witness blind individuals performing tasks that require acute hearing or touch with an impressive level of skill, leading to the logical, though incomplete, conclusion that their sensory organs themselves are superior. The truth lies in the brain's incredible capacity to adapt and reallocate its resources, making the most of the information available through the remaining senses rather than an inherent strengthening of the sensory organs themselves.
