The dominant meta-theories in contemporary sociolinguistics include interactionism, social constructivism, poststructuralism and similarly relativist, anti-realist approaches (hereby grouped within the broader category of interpretivism). This paper argues that anti-scientific, anti-realist tendencies in contemporary sociolinguistics are ill-justified, confuse science with positivism, and weaken sociolinguists' necessary commitment to objectivity (hereby understood as commitment by scientists to explain the ontological order, or what exists regardless of whether it is known by people). The anti-realism in interpretivist sociolinguistics also considerably diminishes the ability of sociolinguists (...) to, for example, make ontological claims about language and its users, study phenomena including linguistic hierarchies and linguistic/social oppression as systems, and develop robust and effective strategies for critical engagement and social emancipation. By reaffirming sociolinguistics as part of the scientific project, and by reframing sociolinguistics within critical realism (CR), this paper offers conceptual alternatives to the dominant interpretivist tendencies in contemporary sociolinguistics.
