Speaking of Occasion Noise “Judgment is like a free throw: however hard we try to repeat it precisely, it is never exactly identical.” “Your judgment depends on what mood you are in, what cases you have just discussed, and even what the weather is. You are not the same person at all times.” “Although you may not be the same person you were last week, you are less different from the ‘you’ of last week than you are from someone else today. Occasion noise is not the largest source of system noise.
