When someone thinks they have all the information, stop volunteering the missing pieces.

When someone is operating from an incomplete picture and does not know it, the missing pieces are yours. Supplying them out of a wish to be understood, to appear open, or to correct the record hands over the only advantage you had. There are relationships where full disclosure is right and obvious. This is about the ones where it is not.

Before filling a gap in someone’s understanding, ask what they will do with the information. If they are working against your interests, say nothing and let their picture stay incomplete. Silence here is not dishonesty; nobody is owed your analysis.
