James Pennebaker, a social psychologist at the University of Texas at Austin, once conducted research on the way people use pronouns in their e-mails. He discovered that the more people use the pronoun “I,” the more likely they are telling the truth and are perceived as such. On the other hand, the more people use “you” or “he/she/they” as the subject of a sentence, the more likely they are to be not telling the truth.
