Welcome to Social Psychology!

Ever wondered why people sometimes follow orders even when they know they’re doing something wrong? Or why we feel so much loyalty to "our team" while being suspicious of others? That is exactly what Social Psychology is all about. We look at how our behavior is influenced by the people around us, the groups we belong to, and the society we live in. Don't worry if it feels like a lot to take in; we’ll break it down step-by-step!


1. Obedience: Why Do We Follow Orders?

Obedience is a type of social influence where an individual follows a direct order from an authority figure. In this section, we look at two main theories that try to explain why we do this.

Agency Theory (Milgram)

Stanley Milgram suggested that we exist in two different "states":

  1. Autonomous State: You feel in control of your actions and take full responsibility for what you do.
  2. Agentic State: You see yourself as an "agent" for someone else. You follow their orders and feel that they are responsible for the outcome, not you.

The switch between these two is called the Agentic Shift. This usually happens when we perceive someone else as having a higher social hierarchy than us.

Analogy: Imagine a soldier. In their private life, they are autonomous. In battle, they might enter the agentic state, following a commander's orders because they believe the commander is the one responsible for the decision.

Social Impact Theory (Latané)

This theory looks at obedience as a result of "social forces." It uses a mathematical-style formula: \(i = f(SIN)\). Impact (\(i\)) is a function (\(f\)) of:

  • Strength (S): How much power or status the authority figure has.
  • Immediacy (I): How close the authority figure is to you (physically or in time).
  • Number (N): How many people are giving the orders.

Divisional Effect: This theory also says that if the social force is spread out over many people (like a large crowd), the impact on each individual person is smaller.

Quick Review: Agency Theory focuses on our mindset (agent vs. autonomous), while Social Impact Theory focuses on the situation (how strong/close the authority is).


2. Researching Obedience: Milgram’s Variations

You’ve probably heard of Milgram’s famous "Electric Shock" study. For your exam, you need to know how he changed the situation to see if obedience would drop (this is called dissent).

  • Telephonic Instructions (Exp 7): The researcher gave orders over the phone. Obedience dropped significantly. Takeaway: Physical closeness (immediacy) matters!
  • Rundown Office Block (Exp 10): The study moved from the prestigious Yale University to a messy office in a poor area. Obedience dropped slightly. Takeaway: The status of the location (strength) matters.
  • Ordinary Man Gives Orders (Exp 13): Instead of a scientist in a lab coat, a person who looked like a "normal" participant gave the orders. Obedience fell to the lowest levels. Takeaway: We need to perceive legitimate authority (strength) to obey.

Common Mistake to Avoid: Don't just say people "did what they were told." Use the term Dissent when they refuse to obey or Resistance when they fight back against the pressure.


3. Factors Affecting Obedience

Why do some people obey while others refuse? It’s a mix of your personality, the situation, and your culture.

Individual Differences: Personality and Gender

  • Authoritarian Personality: Proposed by Adorno, this is a personality type that is very submissive to authority but harsh to those "below" them. They are more likely to obey.
  • Gender: Interestingly, Milgram found that women reported higher stress levels but showed almost identical obedience levels to men.

Situation and Culture

  • Situation: As seen in Milgram's variations, things like proximity (closeness) and uniform change everything.
  • Culture: Some cultures are Individualistic (like the UK/USA), focusing on personal rights, while others are Collectivist (like many Asian cultures), focusing on group harmony. Research suggests obedience levels can vary based on these cultural values.

Section Takeaway: Obedience isn't just about being a "good" or "bad" person; it’s a complex mix of who you are, where you are, and how you were raised.


4. Prejudice: Us vs. Them

Prejudice is a pre-judgment (usually negative) about someone based on the group they belong to. We study two main theories here.

Social Identity Theory (Tajfel & Turner)

This theory says that just belonging to a group is enough to cause prejudice. We don't even need to be competing for anything! It happens in three stages:

  1. Social Categorization: You put yourself and others into groups (e.g., "I am a student," "They are teachers").
  2. Social Identification: You adopt the identity of your In-group (the group you belong to). You start acting and thinking like them.
  3. Social Comparison: To boost your own self-esteem, you compare your in-group to the Out-group. You make your group look better and the other group look worse (In-group favoritism vs. Out-group hostility).

Realistic Conflict Theory (Sherif)

Sherif argued that groups only become hostile when they are in competition for limited resources (like money, jobs, or even a trophy). This is called Negative Interdependence. To fix this, groups need to work together on Superordinate Goals (tasks that neither group can finish alone).

Memory Aid: Think of SIT as "Identity" (it's all in our heads) and RCT as "Resources" (it's about stuff we want).


5. Classic Study: Sherif et al. (1954/1961) - Robbers Cave

Sherif tested Realistic Conflict Theory using a summer camp with 22 boys who didn't know each other.

  • Stage 1: In-group Formation. Boys stayed in their own groups (Rattlers and Eagles) and bonded.
  • Stage 2: Friction. Groups competed for prizes. Name-calling and fights started quickly! This proved that competition leads to prejudice.
  • Stage 3: Reducing Friction. Just "hanging out" didn't stop the fighting. Conflict only ended when they had to work together on Superordinate Goals, like fixing a broken water tank.

6. Contemporary Study: Burger (2009)

Burger wanted to see if people would still obey today, nearly 50 years after Milgram. He made it much more ethical:

  • The "shocks" stopped at 150 volts (the point where Milgram’s participants usually had their biggest moral crisis).
  • Participants were screened by psychologists for mental health issues first.
  • Results: Obedience levels were almost exactly the same as Milgram’s. 70% were willing to go past 150v.

7. Methods in Social Psychology

How do we get our data? We mostly use Self-report data.

Questionnaires and Interviews

  • Closed Questions: Fixed answers (Yes/No, or a 1-5 scale). They produce Quantitative data (numbers).
  • Open Questions: People can write what they want. They produce Qualitative data (words/descriptions).
  • Researcher Effects: Sometimes, a participant changes their answer because of how the researcher looks or acts.
  • Social Desirability Bias: This is a big one! People often lie to look like a better person (e.g., "No, I would never be prejudiced").

Sampling Techniques

How do we pick people for our study?

  • Random: Everyone has an equal chance. Very fair.
  • Stratified: The sample reflects the exact proportions of the real world (e.g., if 10% of the town are doctors, 10% of your sample are doctors).
  • Volunteer: People sign themselves up (often through an ad).
  • Opportunity: You just ask whoever is available at the time.

Quick Review: Quantitative = Numbers (easy to graph). Qualitative = Words (rich in detail).


8. Issues and Debates in Social Psychology

As you finish this chapter, think about these big-picture questions:

  • Ethics: Was it okay for Milgram to stress people out so much? Is the knowledge we gained worth the "harm" to the participants?
  • Nature vs. Nurture: Is prejudice something we are born with (Personality/Nature), or is it learned from our society (Culture/Nurture)?
  • Social Control: If we know how to make people obey, could a government use that to control us? On the flip side, can we use this to reduce rioting or improve heroism?

Final Key Takeaway: Social psychology shows us that we are not islands. Every choice we make is shaped by the invisible "social net" around us. Understanding this helps us build a more tolerant and brave society!
