Epistemic Justice and Credibility Excess

Sor Juana's constant need to defend her intellectual authority—despite evident genius—against those granted credibility by birth, gender, and station reveals epistemic injustice: the structural denial of someone's status as a knower. This concept, grounded in her tradition of marginalized brilliance, examines how privilege grants what philosopher Miranda Fricker calls 'credibility excess'—automatic belief based on social position rather than merit. Sor Juana had to justify her right to think; privileged scholars simply thought. Acknowledging privilege means recognizing this credibility differential: understanding that your ideas circulate more freely, your expertise is questioned less, your voice carries weight assigned by systems rather than earned through argument alone. This awareness becomes the first step toward redistributing epistemic authority and creating genuine intellectual democracy.
