James Pennebaker studies how people use words. More specifically, how they use function words (such as pronouns and articles). His findings are startling and nearly universal. In his book The Secret Life of Pronouns he writes, “In any interaction between two people, the person with the higher status uses fewer I-words. [They also] use first person plural pronouns (we, us, our) at much higher rates than those lower in status.”
APPLY IT: If you want to improve your status and positioning, try removing as many I-words as you can from your emails and face-to-face interactions, and replace them with we-words.
