According to the work of Ludwig Wittgenstein, we risk misunderstanding something as a result of failing to notice logical errors in language used to describe it. In this chapter I introduce and discuss examples of errors that appear to have been difficult for neurotypical people to identify. I argue that an autistically neurodivergent perspective on language use is valuable in identifying the logical errors in language that concerned Wittgenstein. I also argue that a failure of neurotypical society to appreciate that societal language games are, by definition, neurotypical language games can have adverse consequences where autism is concerned because of the inevitability of cultural biases in favour of neurotypicality. Some of these adverse consequences relate to ethical consideration of research to cure/prevent autism.
