Me, Myself, and I
The Harvard Business Review features a Q&A with Dr. James Pennebaker, who describes research which suggests that we unconsciously reveal our personality through our choice of pronouns.
For example, if someone asks you about the weather and you say, “I think it’s hot,” rather than simply, “It’s hot,” that says something about you. (People who are self-focused, depressed, and/or lower in status tend to use “I” more frequently.)
Pennebaker has authored the book, The Secret Life of Pronouns: What Our Words Say About Us.
