JURORS COMMONLY BELIEVE THAT PSYCHIATRISTS, THEMSELVES, ARE 'DISTURBED' AND THAT PSYCHIATRIC EXPERTS SELDOM AGREE ON A PARTICULAR DIAGNOSIS. IF PSYCHIATRIC OR PSYCHOLOGICAL TESTIMONY IS IMPORTANT TO THE CASE, JUROR QUESTIONING SHOULD UNCOVER THESE ATTITUDES. A SERIES OF 32 SAMPLE QUESTIONS ARE GIVEN WHICH COVER THE JUROR'S KNOWLEDGE OF PSYCHOLOGY OR PSYCHIATRY, ANY ASSOCIATION THE JUROR MAY HAVE HAD WITH MENTAL HEALTH EXPERTS, AND JUROR ATTITUDES ABOUT THESE DISCIPLINES. IF ALCOHOL, NARCOTICS, OR OTHER DRUGS ARE INVOLVED IN THE DIMINISHING OF THE CAPACITY OF THE CLIENT AT THE TIME OF THE CRIME, A PROSPECTIVE JUROR'S ATTITUDES TOWARD THESE SUBSTANCES SHOULD BE EXPLORED. A SET OF 13 QUESTIONS COVER THE PROSPECTIVE JUROR'S USE OF ALCOHOL, OPINIONS FORMED AS A RESULT OF READING OR WATCHING MEDIA PUBLICITY ABOUT ALCOHOL OR DRUGS, AND THE JUROR'S UNDERSTANDING OF THE EFFECT OF THESE SUBSTANCES. FINALLY, 7 QUESTIONS COVER THE JUROR'S UNDERSTANDING OF MENTAL RETARDATION AND INTELLIGENCE MEASUREMENTS IN GENERAL. A BIBLIOGRAPHY IS APPENDED.
