Intuition
Knowing without knowing how — a fast judgment whose reasons stay hidden.
What it means
Intuition is the capacity to arrive at a judgment, feeling, or solution rapidly and without conscious, articulable reasoning, drawing on associations and patterns learned through experience. It is the output of fast, automatic processing and often arrives clothed in confidence and affect, which is why it is persuasive even when wrong. Skilled intuition is genuine expertise: in high-validity environments with prompt, reliable feedback, experts internalize regularities and recognize situations accurately, whereas in low-validity environments the same confident intuitions can be illusory. Intuition is not the opposite of analysis but a different route to it, and the two can correct each other. Its trustworthiness depends less on how certain it feels than on the conditions under which it was trained.
Examples
An experienced nurse senses a patient is deteriorating before the monitors confirm it, having unconsciously read subtle cues from many prior cases.
A grandmaster glances at a board and the right move simply suggests itself — thousands of games have taught her patterns she cannot put into words.
An interviewer is certain within thirty seconds that a candidate is right for the job, but hiring gives feedback too late and too rarely for that certainty to have been trained on anything.
