Trial by jury is considered the gold standard for fairness in a criminal case. Jurors are instructed to make decisions based only on the evidence presented. In a predicting brain, however, this is an impossible task. The jurors perceive every defendant, plaintiff, witness, judge, attorney, courtroom, and iota of evidence through the lens of their own conceptual system, which makes the idea of the impartial juror an implausible fiction. In effect, a jury is a dozen subjective perceptions that are supposed to yield one fair and objective truth.
