Notice who says “I” when the team did it and who says “we” when they did it alone.

Pronouns are a cheap and surprisingly reliable readout of how somebody handles credit. Taking the group’s work into the first person, and handing your own work to the group, are two small habits that tell you most of what you need to know about working with a person. Almost nobody watches their own pronouns, which is exactly why they stay honest.

Listen for it this week in a team or group project, without announcing that you are doing it. Then check your own last few accounts of something that went well. If you have been saying I where we would be truer, correct it once in front of other people.
