Savant is a clinical term historically used to describe people with developmental differences who show exceptional ability in a particular area, such as memory, music, art, or mathematics.
While some individuals do have remarkable specialised skills, the term is controversial because it has often been used to stereotype autistic people — implying that they are either geniuses or lacking, rather than recognising the full diversity of autistic experience.
Many autistic advocates and researchers now prefer to describe specific abilities or interests without using the label savant, to avoid reinforcing these narrow or sensationalised views.
