incomplete information
Not the whole picture
Incomplete information describes a situation where relevant facts are missing, unknown, or unavailable.
The term appears in game theory and economics to describe scenarios where participants don't know everything about other players' circumstances or intentions.
More broadly, it captures any decision-making context where you're working with partial knowledge: We had to act on incomplete information.
The phrase acknowledges uncertainty without implying fault—the information simply isn't there.
