This article tests conversion theory through linguistic analysis of group discussions and also tests the effects of linguistic mimicry in homogeneous groups and minority/majority groups. Supporting conversion theory, majorities had a more interpersonal, outward focus as tested through use of more third person plural pronouns ("they"). Supporting conversion theory’s validation process, minority members who used a higher percentage of causation words were more influential. Majority members who used more second person pronouns ("you") had less influence in the group, in support of previous research that found that "you" words were counterproductive with conflict. It was hypothesized that there would be a positive relationship between linguistic mimicry and discussion of information shared by all group members, but this was only found in homogeneous groups.
