ABSTRACT: We examined the old (Caljic) and new (Calcrim) standardized criminal jury instructions for the state of California for juror comprehension and objectivity of legal terminology. Three-hundred and twelve native English speaking participants acted as mock jurors and read through a trial transcript that varied juror instructions (Calcrim, Caljic, or non-descript instructions). After completion of the trial transcript, jurors were asked to render a verdict, recommend a sentence, and were questioned on comprehension, the legal definitions of reasonable doubt, circumstantial and direct evidence, and intent. Results demonstrated that jurors comprehended the new instructions significantly better compared with the old instructions. This comprehension was shown by jurors reaching a correct verdict significantly more often with the new instructions compared with the old. It was also shown that jurors could better identify reasonable doubt and evidence significantly better in the new instruction condition compared with the old and non-descript conditions.
