SINCE THE 60-ITEM QUESTIONNAIRE AND INTERVIEW FORMAT USED IN THE STUDY INVOLVE SELF-REPORT INFORMATION, QUESTIONS WERE REPEATED WITH VARIED WORDING TO CHECK FOR INTERNAL CONSISTENCY (WHICH WAS SHOWN TO BE STRONG). INFORMATION OF THE DEMOGRAPHIC TYPE WAS SOUGHT, ALONG WITH PERCEPTIONS OF LAWYERS' AND JUDGES' EFFECTIVENESS, JUROR ACTIVITY LEVEL, AND THE JURORS' ABILITY TO UNDERSTAND THE PROCEEDINGS AND THE LAW. THE FINDINGS THAT JURORS RELY ON EVIDENCE AND TAKE THEIR ROLE SERIOUSLY INDICATE THAT JURORS ARE REASONABLE AND SENSITIVE. RESULTS CONCERNING JUROR PERCEPTIONS SUGGEST THAT JURORS ARE CONCERNED WITH BEING FAIR AND JUST (A FINDING CONTRARY TO THAT OF CRITICS OF THE JURY SYSTEM WHO FEAR THAT JURORS ARE FREQUENTLY BIASED OR INCOMPETENT). JURORS APPEARED NOT TO BE INFLUENCED BY SUBTLE SOCIOPERSONAL CONSIDERATIONS SUCH AS THE DEFENDANT'S OR ATTORNEY'S PERSONAL STYLE OR APPEARANCE. OVERALL, THEY VIEWED THEIR PARTICIPATION AS A CIVIC RESPONSIBILITY, CONCLUDED THEIR WORK WITH A SENSE OF PRIDE AND GRATIFICATION, AND POSSESSED AN ABILITY TO EMBODY THE COLLECTIVE WISDOM AND RESPONSIBILITY OF THE LARGER COMMUNITY THEY REPRESENT. THESE FINDINGS APPEAR TO BE IN CONFLICT WITH RESEARCH THAT USES MOCK JURORS AND SIMULATIONS. PERHAPS MOCK JURORS ATTEND TO MISLEADING, EXTRANEOUS VARIABLES BECAUSE THE OVERRIDING CONCERNS WITH JUSTICE AND RESPONSIBILITY TO THE COMMUNITY ARE NOT PRESENT AS THEY ARE WITH ACTUAL JURORS. THUS, THIS STUDY OF REAL JURORS IS OFFERED AS A FIRST APPROACH TO UNDERSTANDING ACTUAL JUROR BEHAVIOR. TWELVE REFERENCES ARE INCLUDED.
