But what is often called an intuition is really an impression based on logical deduction or experience. When an expert feels that there is something wrong about a picture or a piece of furniture or the signature on a cheque he is really basing that feeling on a host of small signs and details. He has no need to go into them minutely—his experience obviates that—the net result is the definite impression that something is wrong. But it is not a guess, it is an impression based on experience.
