Language development, linguistic input, and linguistic racism.

Language development is both remarkable and unremarkable. It is remarkable because children learn the language(s) around them, signed or spoken, without explicit instruction or correction. It is unremarkable because children have done this for thousands of years without worldwide incident or catastrophe. Yet, much research on this organic developmental phenomenon relies on an empirical falsehood: "quality" linguistic input is necessary to facilitate language development. "Quality" is a value judgment, not a structural feature of any human language. I argue selectively legitimizing some linguistic input as "quality" is possible only through mischaracterizing what language is. This falsehood is also linguistic racism because it is based on a deficit perspective of the early linguistic experiences of a subset of children, specifically racialized children. I explore how linguistic racism stalls our collective understanding of language development and promotes an environment of bad science.
