This study aimed at finding the impact of having multiple options for jurors as is the case in Scotland (guilty, not guilty, not proven), relative to the usual setting of guilty or not guilty verdict.

The response was measured using the sum of the scores for 11 ratings (rounds) on a Likert scale ranging from 0 (no evidence of guilt) to 14 (guilty).
