 Although Schütze (1996) and Cowart (1997) are both critical of traditional Essentialist informal elicitation methods, their primary concern is to show how the claims of Essentialist linguistics can be made less vulnerable to legitimate complaints about informal data collection methods. Broadly speaking, they are friends of Essentialism. Critics of Essentialism have raised similar concerns in less friendly terms, but it is important to note that the debate over the reliability of informal methods is a debate within Essentialist linguistics as well.
