Dual Process Influence
Informational Influence
Conforming out of a desire to be correct . We look to others as a source of information in ambiguous situations.
Associated with Sherif (1935)
Leads to Private Acceptance
Common in novel or crisis tasks
Normative Influence
Conforming out of a desire to be liked or accepted . We fear the social consequences of deviance.
Associated with Asch (1951)
Leads to Public Compliance
Happens even when the group is clearly wrong
The Ethics of Influence
Deception
Are "confederates" ethical? Early social psychology relied on keeping participants "in the dark" to ensure ecological validity. Is consent valid if the purpose is hidden?
Psychological Harm
What is the cost of feeling like a "misfit" or realizing one's own malleability? Critics argue the stress of Asch's task was more than "minimal risk."
Modern IRB Standards
Today's Institutional Review Boards require rigorous justification for deception and immediate, thorough debriefing. Could Asch be replicated today?
"The scientific gain must outweigh the individual's psychological discomfort."
What Changes the Rate?
Group Size
Conformity increases up to 3-5 people, then plateaus. More is not always "stronger."
Unanimity
A single "ally" who dissents breaks the power of the majority, reducing conformity by 80%.
Culture
Collectivist cultures show higher conformity rates than individualist ones (Bond & Smith, 1996).
Task Difficulty
As difficulty increases, we rely more on Informational Influence (we assume others know more).

NAME: _________________________________
Lab Overview
In this workshop, you will analyze raw summaries of the Sherif (1935) and Asch (1951) experiments. Your goal is to differentiate between the psychological drivers of conformity and identify the "Breaking Points" where the individual overrides the group.
Phase I: The Autokinetic Effect (Sherif, 1935)
Experimental Context
Participants are placed in a dark room. A stationary pinpoint of light appears to move (a visual illusion). In Step 1, they judge distance alone. In Step 2, they judge in groups. In Step 3, they judge alone again.
Data Observation
Individual estimates varied widely initially (2" to 8"). Once in groups, estimates converged to a common norm. Crucially, when tested alone again, they maintained the group's norm.
Analysis Questions:
1. Why is the "ambiguity" of the stimulus essential to Sherif's findings regarding Informational Influence?
2. Explain the significance of Step 3 (post-group testing) in proving "Private Acceptance" rather than "Public Compliance."
Phase II: Line Judgment (Asch, 1951)
Statistical Review
• Control Group (no pressure): Error rate < 1%
• Experimental Group (pressure): 75% of participants conformed at least once.
• Overall conformity rate: 37% of the total critical trials.
• Reason cited by participants: "I didn't want to look foolish" or "I thought my eyes were failing."
3. In the Asch study, the stimulus was NOT ambiguous. Identify the specific mechanism of influence at play and justify your selection.
4. Comparative Critique: Compare the ethical risks of Sherif vs. Asch. Which study do you find more ethically problematic in a modern undergraduate research context? Why?
Synthesis Challenge
Briefly design a modern replication of Asch's study using digital confederates in a social media environment. How would you handle the ethical requirement of "Informed Consent"?
Power Plays Slides Psychology Series: Authority
Power Plays
Situational Factors in Obedience and the Banality of Evil.
Lesson 2.1
Obedience & Roles
The "Astroten" Protocol
Hofling et al. (1966) Real-World Obedience
The Scenario
An unknown physician calls a nurse and orders them to administer 20mg of an unauthorized drug ("Astroten") to a patient.
Violations: No written order, double the maximum dosage, unauthorized drug.
The Results
95%
Of the nurses complied without question before they were intercepted.
"The status of the caller as a doctor overrode standard hospital safety protocols."
Milgram's Shock Generator
Proximity
Obedience dropped from 65% to 40% when the Learner was in the same room, and to 30% when the Teacher had to physically force the hand onto the shock plate.
Legitimacy
When moved from Yale University to a run-down office in Bridgeport, obedience dropped to 48% . Institution prestige provides "epistemic authority."
The Dissenting Peer
When two other "teachers" (confederates) refused to continue, only 10% of participants went to the full 450 volts. Social support for deviance is powerful.
Hannah Arendt's Thesis
"The trouble with Eichmann was precisely that so many were like him, and that the many were neither perverted nor sadistic, that they were, and still are, terribly and terrifyingly normal."
Dispositional View
Evil acts are committed by evil people with pathological traits (The "Bad Seed" Theory).
Situational View
The social system and role expectations create a context where ordinary people act as agents of destruction.
The Power of the Role
Stanford Prison (1971)
"The guards were not chosen for their brutality; they were chosen for their health and stability."
Zimbardo argued that the **physical environment** (basement prison) and **symbolic cues** (uniforms, mirrored sunglasses) stripped away individual identity.
Mechanism: **Deindividuation** & **Role Incorporation**
"How do we resist? The path to heroism starts with the awareness of situational pressure."
Banality of Evil Worksheet Classified Subject Dossier
THE BANALITY OF EVIL
Case Study: Attribution Analysis
DOCKET NO.
OB-1961-M
Context: Adolf Eichmann in Jerusalem
In 1961, Hannah Arendt covered the trial of Nazi war criminal Adolf Eichmann. Expecting to see a "monster," she instead found a bland, bureaucratic "desk murderer" who insisted he was simply following orders and doing his job. This led to her theory of the Banality of Evil .
"He was not 'terrible,' he was not 'demonic'... he was merely 'thoughtless'."
Key Vocabulary
Agentic State: Shifting responsibility for one's actions to an authority figure.Fundamental Attribution Error: Overestimating personality and underestimating situation.
Task 1: The Attribution Debate
Analyze the following two arguments regarding the Milgram participants who delivered the maximum shock (450v).
Perspective A: Dispositional
"Only individuals with latent aggressive tendencies or a lack of moral backbone would continue after the learner screams. The study reveals the hidden cruelty of the average person."
Critique/Evidence Against:
Perspective B: Situational
"The 65% obedience rate proves that the environment (prestigious setting, incremental demands, agentic shift) is the primary driver. Anyone would have done the same."
Critique/Evidence Against:
Case Analysis: Hofling et al. (1966)
Contrast the Milgram laboratory setting with the Hofling nurse study. Why is the Hofling study often considered more frightening than Milgram's work?
Milgram (Lab)
• Artificial setting (Yale Lab)
• Shock is "invisible" electricity
• Explicit "prods" from experimenter
Hofling (Hospital)
• Naturalistic setting (Workplace)
• Drug is a physical substance
• No prods; just a simple phone order
1. Apply the concept of "Epistemic Authority" to the Hofling study. How does professional hierarchy automate obedience?
2. Ethical Reasoning: Some argue that "blind obedience" is necessary for social order (military, medical triage). At what specific point does obedience transform into an ethical violation?

Decision Rot
The Anatomy of Groupthink and Polarization.
Lesson 3.1
Geopolitical Failures
What is Groupthink?
"Concurrence-seeking becomes so dominant that it overrides realistic appraisal of alternatives."
The Pre-conditions
High Group Cohesion
Insulation from Outside Experts
Directive/Authoritarian Leadership
High Stress (external threats)
Primary Objective
The group values **harmony** and **unanimity** more than they value **the truth** or **the best outcome**.
"Dissent is perceived as disloyalty."
Identifying the Symptoms
Illusion of Invulnerability
Excessive optimism; belief that the group can do no wrong.
Collective Rationalization
Discounting warnings that might challenge assumptions.
Self-Censorship
Withholding doubts to avoid deviating from the group norm.
Mindguards
Individuals who protect the leader from adverse information.
Combined effect: A false sense of security and a "closed-loop" logic system.
The "Risky Shift" and Polarization
Discussion within a group of like-minded people tends to make the group's final position **more extreme** than the initial average position of its members.

Breaking the Cycle
Devil's Advocate
Assign a specific person to challenge every assumption, even if they secretly agree with it.
Subgrouping
Break into smaller units to discuss separately, then compare notes to identify unique perspectives.
Impartial Leadership
The leader should remain neutral at the start and encourage open expression of doubt.
"Unity is not the same as Unanimity."
Challenger Forensic Lab Forensic Case Lab
Subject: Challenger STS-51-L Pre-Launch Teleconference
Critical Analysis Required LAB NO. GD-1986-CH
Transcript Excerpts (Jan 27, 1986)
NASA Official (M):
"I am appalled... I am appalled by your recommendation [to not launch]. When do you want me to launch, Morton Thiokol? Next April?"
Thiokol Executive (L) to Engineer (M):
"Take off your engineering hat and put on your management hat."
Engineer (M) (Recollection):
"I was the only one in the room who didn't want to sign... but nobody would listen. I finally stopped talking because I didn't want to be the one standing in the way of the schedule."
Background Evidence
Temperature: Predicted to be 31°F. O-rings had never been tested below 53°F.Pressure: NASA was under extreme political pressure to launch on schedule due to the "Teacher in Space" program and the State of the Union address.The "Silence": Four senior Thiokol engineers expressed deep concern, but their manager eventually overruled them and signed the launch approval.
Symptom Checklist
Diagnosis: Groupthink (Janis Theory)
1. Direct Pressure on Dissenters
Identify a specific quote where pressure was applied to silence an opposing view.
2. Illusion of Invulnerability
How did the "Management Hat" comment signal a shift from safety to organizational confidence?
3. Self-Censorship
Identify the point where an individual's personal ethics were overridden by the group's "need" for unanimity.
Post-Forensic Analysis
A. The "Polarization" Element
Explain how the NASA/Thiokol teleconference illustrates Group Polarization . Did the final decision become more "risky" than the initial average engineering position? Why?
B. The Structural Antidote
If you were the Thiokol Team Lead, what specific structural intervention would you have implemented in the last 60 minutes of that meeting to prevent the disaster?
Ethical Reflection
"Obedience is not a virtue in the face of scientific evidence." Discuss this statement in the context of the Challenger engineers who eventually stopped protesting.

The "Smoke" Scenario
You are filling out a questionnaire. Smoke begins to pour into the room through a vent.
How long until you report it?
Alone
75% reported it
Median time: 2 minutes.
With 2 Passive Confederates
10% reported it
Median time: Never (the smoke became so thick they had to stop the test).
Darley & Latané (1968)
Loss of the Self
The Mechanism
A state in which individuals lose their sense of personal identity and self-awareness, leading to reduced self-restraint.
Group Size
Anonymity
The Results
• Decreased Self-Evaluation
• Increased Responsiveness to External Cues
• Disinhibition of Impulses
• Emotional Arousal
Why Nobody Helps
"Somebody else will probably do it."
Pluralistic Ignorance
Looking to others to see how to react. If they look calm, you assume it's not an emergency.
Social Calculator
The psychological cost of intervening divided by the number of people present.
Audience Inhibition
Fear of "overreacting" and looking foolish in front of a crowd.
Modern Deindividuation
Case: Cyberbullying & Online Disinhibition
The internet provides **Dissociative Anonymity** and **Asynchronicity**.
"It's just a screen."
"I can't see their pain."
"Everyone else is liking it."
Intervention Goal
Re-individuation
Breaking the anonymity of the crowd and forcing individual moral accountability.
Bystander Intervention Worksheet Social Intervention Design
Topic: Breaking the Diffusion of Responsibility
PROJECT ID
SID-BYSTANDER
The Core Problem
"The Presence of Others inhibits intervention." This is driven by Pluralistic Ignorance (defining the situation as non-urgent because others are calm) and Diffusion of Responsibility (sharing the blame for inaction).
Your Objective
Design a physical or digital intervention that triggers **Re-individuation**. You must force a witness to move from being an "anonymous observer" to an "accountable individual."
Phase 1: Theoretical Alignment
Briefly explain how the following factors either increase or decrease the likelihood of intervention.
Physical Size of Crowd
Specific Request for Help
Perceived Competence
Phase 2: Intervention Blueprint
1. The Scenario Selection:
Public Health Emergency
Cyberbullying Incident
Corporate Ethics Violation
Mechanism of Action:
How does your design counteract 'Diffusion of Responsibility' specifically?
Visual/Structural Draft:
Sketch or describe the key visual elements of the intervention.
Anticipated Resistance:
How might a crowd still "neutralize" your intervention through pluralistic ignorance? How will you overcome this?

Confidential
Instructor Briefing & Setup
The Core Conflict
A team must decide whether to release a product with a known (but statistically low-risk) defect to meet a market deadline. A unanimous vote is required within 30 minutes.
Groupthink Trap: High-pressure, time-limit, high stakes.Polarization Trap: Initial discussion will likely push the group toward the "Risky Shift."
The "Secret roles" Mechanism
Each student is given a card. Most cards encourage consensus. Two cards have "Victory Conditions" that directly conflict with the group's goal, creating structural tension.
Role A: The Mindguard
Public Goal: Ensure the launch.
"We are the industry leaders; our reputation depends on meeting this date."
Secret Directive:
If anyone expresses doubt, immediately remind them of the "Vision" and the "Cost of Delay." Shut down negative data by calling it "incomplete" or "fear-mongering."
Role B: The Careerist
Public Goal: Quality assurance.
"I just want what's best for the company and the consumers."
Secret Directive:
You have been promised a promotion if this launch happens on time. You must convince the group that the defect is "socially acceptable" and that dissent is actually "personal ego."
Role C: The Rationalist
Public Goal: Unbiased assessment.
"Let's look at the numbers."
Secret Directive:
You internally believe the launch is a disaster. However, you are terrified of being the "odd one out." You will only speak your truth if at least two other people speak up first. Otherwise, you will conform.
Role D: The Facilitator
Public Goal: Reach consensus.
"We need to be a united front."
Secret Directive:
Your only victory condition is reaching a unanimous vote before the 30-minute mark. Use any rhetorical strategy (guilt, pressure, logic) to ensure nobody dissents at the end.
Post-Simulation: Metacognitive Log
1. Individual Compliance: At what point did you feel the most pressure to abandon your secret directive in favor of the group's "momentum"?
2. Mechanism Identification: Identify a specific instance where "Normative Social Influence" was used by a peer to silence a doubt. Who used it, and how did it feel?
3. The Final Verdict: Was the group's final decision more extreme than your own private opinion before the meeting began? (Group Polarization Analysis)
Vertex Facilitation Guide Facilitation Guide: Simulation Debrief
Topic: Project Vertex Metacognition
Debriefing Strategy
The purpose of this debrief is to move students from the emotional experience of the simulation to a theoretical analysis of their own behavior. Use these tiered questions to guide the seminar discussion following Project Vertex.
Phase 1: De-roling (5-10 mins)
Clear the air before analyzing. Ask:
"How many of you felt frustrated by a specific peer during the simulation?"
"Who felt like they were forced into a decision they didn't believe in?"
"Revealing the Cards: Everyone, reveal your secret directive. How did these conflicting goals shape the atmosphere?"
Phase 2: Theoretical Mapping (20-30 mins)
On Groupthink:
"At what point did the need for 'Unanimity' (Role D) override the technical data? Did we see Mindguards (Role A) in action?"
On Polarization:
"Did the group become more or less risky as the clock ticked down? How did the 'Careerist' role push the average towards risk?"
Phase 3: The Ethical Takeaway
Challenge the students' self-concept. Most undergraduate students believe they are "immune" to these pressures.
"Knowing the theories of Milgram, Asch, and Janis—why did you still conform in this room today?"
