 More recent criticism has been in the form of rival theories, including "Subject-Sensitive Invariantism" (SSI), mainly due to the work of John Hawthorne (2004), and "Interest-Relative Invariantism" (IRI), due to Jason Stanley (2005).SSI claims that it is the context of the subject of the knowledge attribution that determines the epistemic standards, whereas Contextualism maintains it is the attributor.IRI, on the other hand, argues that it is the context of the practical interests of the subject of the knowledge attribution that determines the epistemic standards.
