The jury consultant can be a very important member of any defense/prosecution team. This psychologist uses numerous past studies of juror behavior in order to maximize the probability of a juror swaying towards his teams side when it comes time to decide the defendants fate. These consultants can be stunningly accurate and could make or break the trial. A particular example of a selection process involves the defendant's occupation--many jury consultants will immediately protest any teachers that are on the jury. It has been found that such members tend to be more judgmental and are likely to vote for guilty. Secondly, often blue collar workers are removed when possible. Its seems that these members of society tend to see things more in black and white with very little gray allowed (i.e., alternative explanations are rarely accepted).

Jury consultants may also use a number of questions in order to evaluate a jury members personality characteristics. They will often (if working for the defense) try to eliminate anyone they define as having an authoritarian personality. Again these individuals are very judgmental and are very unlikely to sway from there stances. They also hold a large influence over jury members. A new personality measure that is often considered is a person's level of moral reasoning. This involves the level to which a person's moral beliefs have developed. For example, a high moral reasoning will go beyond the law if it seems to be morally unacceptable. They will also be less prejudiced towards racial and socioeconomic differences (something that is a major problem with today's courts).
