Comment on the meaning of 'proof beyond a reasonable doubt'

Abstract

In view of the variety of predispositions among jurors regarding the meaning of proof 'beyond a reasonable doubt', some quantitative definition of the probability of guilt required for conviction in addition to descriptive phrasing- in particular stressing the importance of avoiding conviction of the innocent-is desirable. Some flexibility should be left to the discretion of the jurors. Whether any articulation of a standard-in words or percentages-will have an appreciable effect on the rate of improper convictions is not clear.
