These instructions will function best if specific references to the case being tried are inserted. For example, every time we have put the word “defendant” in brackets we intend the instructing judge to substitute the defendant’s actual name. The same holds true when the word “witness” is bracketed. General studies of juror understanding suggest that juries understand better when actual names are used rather than terms like “defendant” or “witness.” On the same rationale, we have used the term “I” rather than the third person “the court” when referring to the judge. Finally, where we have given alternatives, select the alternative(s) that best fit(s) the evidence in your case.
