Juries as “Small Groups”Juries as “Small Groups”• A citizens jury is a type of “small group”• Small group- a group “in which there is the
possibility of simultaneous face-to-face interaction among most or all members of the group.”
• Small groups are important for several reasons:– Range of ideas, opinions, and concerns– Consensus– Active participation and interaction– Promote sense of equality between members – Useful for deliberation of controversial issues– Increase efficiency and productivity of group

Overview of the Roles of a Citizens Jury Overview of the Roles of a Citizens Jury GroupGroup
– Central role of deliberative group processes • aim is to “obtain reasoned agreement among free
and equal citizens…by considering information from expert witnesses and by deliberating together on the merits of different opinions”
Task interdependence– each person’s contribution to the group has implications for other’s contributions, and ultimately affects the group outcome.

Member CharacteristicsMember Characteristics• What are member characteristics?
– traits, skills, or abilities of individual group members.
• Why are they important?– Group performance as a WHOLE related to member
characteristics of group members– Potential group productivity=sum of all the
individual inputs • Composition Effects—
– Group composition has been known to affect the events that occur within group proceedings

SMALL GROUP DYNAMICSA SPECIAL CASE: JURY DELIBERATIONS
![Page 15: Psy 270 Group Dynamics Presentation (Jury Deliberation) Sp11](https://reader035.vdocument.in/reader035/viewer/2022081516/54b77d654a7959bb328b458f/html5/thumbnails/15.jpg)
What about studying group behavior in juries?
• Mock Juries (often referred to as “focus groups” in law schools)– Taking them seriously
• “People who participate in mock juries must be convinced that the case being presented is a real case with real consequences” – Dr. David Ball, national jury expert (specializes in mock juries)
– Mock Jury formation• Composition must be based on the true demographical information of the
particular venue (i.e., the county) in which the mock jury is being used – Dr. David Ball
– Presenting the case (from an interview with Dr. David Ball)• A “jury study”• Can present a whole trial (i.e., opening statements, witness/ victim testimony,
closing arguments/ summation) OR separate parts of the trial• The mock jury leaves to deliberate
– Returns a final “verdict” for the case– Mock jury deliberations often recorded (this is how the group dynamics are studied)

So….What group dynamics concepts did
you see in the clip that we have discussed in class?

12 Angry Men/ Jurors:Summary of Some Group Behaviors
• Common fate and similarity of jurors (at least in the sense that they are all members of the jury being portrayed)– Two basic “requirements” for consideration as a group
• Stereotyping/ Prejudice (profound!)– “You know how these people lie!”– “And let me tell you, they don’t need a real big reason to kill someone, either!”– “They get drunk. They’re real big drinkers, all of them!”– “That’s the way they are, BY NATURE!”– “There’s a danger here! These people are dangerous!”
• Minority Influence– Man at beginning of clip attempts to persuade the rest to take his [prejudiced]
side
• Majority Influence– The rest of the jurors silence the [prejudiced] man
• Stand up from their chairs• Tell the man to sit down
