Judges hated guide lines because they want the freedom to administer justice as they feel that justice needs to be served. When you give people unlimited freedom to make judgments, you are going to get more noise than you expect. And in the judicial case, i think a disastrous anomon yet it kind of reminds me of michael lewis's book money ball.
Imagine that two doctors in the same city give different diagnoses to identical patients. Now imagine that the same doctor making a different decision depending on whether it is morning or afternoon, or Monday rather than Wednesday. This is an example of noise: variability in judgments that should be identical.
Shermer speaks with Nobel Prize winning psychologist and economist Daniel Kahneman about the detrimental effects of noise and what we can do to reduce both noise and bias, and make better decisions in: medicine, law, economic forecasting, forensic science, bail, child protection, strategy, performance reviews, and personnel selection.
