 The solution to argumentative injustice might be simply for the listener to take care to treat arguers on their own terms. This would avoid viewing people in terms of group membership, a practice that leaves reasoners vulnerable to stereotype-thinking (Govier 1993, 1999). However, sometimes people’s social identities are relevant to the credibility of what they say, when, for instance, it concerns their personal experience of discrimination. Also, social stereotypes influence our thinking unconsciously, in a way that earns the label “implicit bias”. This bias differs from in-group bias but works alongside it, sometimes reinforcing it and sometimes conflicting with it. As a result, women often hold prejudices against other women (and even themselves) just as men do, and people of color may hold unconscious biases against their own ethnicity. When such bias persists despite conscious beliefs to the contrary, psychologists describe it as “aversive bias” (Greenwald &amp; Banaji 1995; Jost, Banaji, &amp; Nosek 2004; Kay &amp; Zanna 2009).
