Social Influence
Şimdi de bireyin grupla olan ilişkisinden
bahsedeceğiz. Çünkü bireyler tek başına yaşayamaz, çalışamaz, öğrenemezler. Hepimiz, yaşamımız
üzerinde önemli etkilere sahip olan grupların üyesiyiz. Bir toplumda birçok kişi, birden
fazla aile, arkadaş çevresi, klüp, örgüt, siyasal parti, ekonomik, dinsel ve mesleki gruba üyedir.
How do other people shape our behavior, and how do we shape others’behaviors, in turn?.
Three broad types of influence comprise the focus:
Conformity
Obedience
Compliance
Conformity -- Classic experiments
M. Sherif (1937): Individuals asked to view a stationary light
- Task: estimate how far the light had moved when viewed in a darkened room
- (The light had not moved at all)
- Sometimes performed the task alone, sometimes with others in the room
- Estimates varied according to # of people in the room, and whether confederates gave high/low estimates
S. Asch (1951): Individuals given a card with a vertical line printed on it
- Participants asked to then look at another card with three lines on it: two did not match, one did
- Task: select line that matched the length of the line on the original card; correct answer was clear
- Individuals often chose a clearly wrong option if confederates first chose a wrong option
[pic]
By the end of the experiment, most people agree with the group (even though its very easy to see that the answer is wrong).
The pressure to conform (agree) to what other people say (do) must be very strong, because the correct answer is so easy to see.
Conformity
Results indicate that we often conform: why?
Two influences: informational and normative
Informational: We seek others’ opinions on what is correct if we suspect they might know better than we do
Normative: We want to fit in, be liked, avoid looking foolish
Minority Influence
Unanimous majority influences us powerfully
Yet: one person’s dissent can break the hold of the majority
Appears not to stem from creation of an ‘alliance’ – occurred even when dissenter also chose an incorrect response, as long as it differed from that chosen by the majority
Factors that affect Social Conformity
Size of Group: Conformity tends to increase as the size of the group increases. But there is little change in conformity once the group size reaches 4-5.
Anonymity (i.e. secrecy): When participants could write their answers down rather than announce them in public, conformity dropped.
Ambiguity (i.e. uncertainty) / Difficulty of Task: When the (comparison) lines (e.g. A, B, C) were made more similar in length it was harder to judge the correct answer and conformity increased. The more difficult the task the greater the conformity.
Status and Knowledge: If someone is of high status (e.g. your boss) or has a lot of knowledge (e.g. your teacher), they might be more influential, and so people will conform to their opinions more. The higher the status the higher the conformity
Social influence: Obedience
Some obedience obviously necessary for life in a complex society
But: Why do we obey commands that result in atrocities – Nazi death camps, Khmer Rouge massacres, Soviet “purges”, etc.?
Two possible sources of obedience: dispositional trait of obedience and situational aspects
Personality and Obedience
Authoritarian personality: beliefs about power, obedience, and importance of strong leadership
More investigations since the 50s and 60s have focused on related fears/ beliefs / attitudes:
Need for order or structure
Intolerance of ambiguity
Concern with death and societal instability
Situations and obedience
Hannah Arendt, in writing about the trial of Adolf Eichmann, who engineered the death and execution of 6 million Jews and other minorities in the Nazi death camps:
“The trouble with Eichmann was precisely that so many were like him… terribly and terrifyingly normal.”
In other words …
The situation was the prime variable to investigate
What aspects of the situation are salient in driving this kind of obedience? How coercive need it be?
Milgram’s experiments: sought to answer these questions
Series of experiments run that have influenced decades of thought and follow-up studies
Milgram’s experiments
Participants: told they would be delivering shocks in a learning experiment
No shocks were ever actually delivered: confederates were actors
Shock level: dials labeled mild-to-deadly: 15 to 450+ mv
“Teacher” (participant) and “Learner” (confederate) separated into 2 cubicles, but could hear each other
“Teacher” instructed to shock “learner” in increasing amounts of voltage, whenever learner made a mistake
[pic]
Method: 40 males aged 20-50 were found to take part (through a newspaper advertisement), and paid $4.50 to participate in a study regarding 'memory'.
Participants were introduced to a man called, Mr. Wallace. Mr. Wallace was tied into a chair with electrodes on his hands.
The participant was taken to another room and told to ask the Mr. Wallace questions (using a telephone).
Each incorrect answer was punished with an electric shock (given by the participant), beginning at 15 volts (very mild), going up by 15 volts for every incorrect answer up to 450 volts (danger - severe shock, xxx). Mr. Wallace said he had a mild heart condition.
Shocks were received in silence up until 300 volts. Then Mr. Wallace complained of having heart trouble and hit on the door and asked to be let out. He then refused to answer any more questions. After a short while he became silent: maybe unconscious or perhaps dead.
If the participant questioned the experimenter, they were told four things:
1. Please continue
2. The experiment requires you to continue
3. It is essential that you continue
4. You have no choice, you must continue.
If the participant still refused to give any more shocks, they were allowed to stop.
Milgram’s experiments -Result
No one actually stopped below the level of intense shock.
22.5% stopped at 315v (extremely intense).
65% continued up until the maximum shock of 450v.
BUT…
Participants showed signs of extreme tension in experiment
(biting fingernails, sweating, trembling, stuttering, and groaning: three participants actually had full blown seizures)
During debriefing the participants completed a follow up questionnaire.
84% of them felt glad that they participated, 74% learnt something of personal importance.
Milgram’s experiments -Result
Profound ethical questions:
Under what conditions can you cause someone to believe that they have behaved in this way?
Is it ethical to do this to someone? (Self-knowledge, stress, etc.)
Does the gain from doing the experiment outweigh the distress caused to the participants (the teachers)?
Compliance
Norm of reciprocity: we feel compelled to comply when someone has helped us in the past
2 related techniques:
“Door in the face” technique: If a large request is followed up by a smaller request, compliance with request increases dramatically: “You conceded, now I have to concede”
“That’s-not-all” technique: “freebie” offered after initial offer tendered, and price seems more reasonable than if both were initially included in the offer
We all use conformity, obedience, and compliance: some more effectively!
LEADERS: most effective users of these social psychology principles
Two theories of leaders:
1) Great-person theory:
Leaders arise due to personal characteristics
2) Circumstances of context:
Leaders require the context of the times in which they lived/led
Group Dynamics
Study of mutual influences of individuals and groups on each other
Behaving in groups:
Social facilitation: “mere presence” effect: we compete harder when others are nearby
Social inhibition: the opposite effect – we sometimes perform more poorly when others are near
Social Loafing
What if no one is the “audience,” and therefore all must perform?
Ringelmann (1913): in a group of men, each pulled less hard than if pulling solo
Latane (1981): “social loafing”
* People work less hard in groups
* Consistent across cultures, across many variables
Deindividuation
Sometimes: others’ presence drastically changes our behaviors
Riots, lynch mobs, etc.: behavior can become disinhibited, cruel, vicious
Deindividuation: we lose awareness of ourselves as individuals, feel less responsible for our behavior
Role we play: may obscure our individuality as well
Thinking in Groups
Group polarization:
* Groups decisions are more extreme than those we make on our own
“Risky shift”
* Greater willingness for a group to take risks than when we are acting as individuals
Many processes affect groups’ ways of behaving/deciding
* Confirmation bias, cognitive dissonance, self-enhancement, false consensus, normative thinking, etc.
Helping and Altruism
How do social environments influence helping behavior?
“The Bystander Effect”
Our understanding of the situation influences our decisions on acting or not acting
Pluralistic ignorance: if others are not doing anything, probably nothing needs to be done
Problem: others are using the same reasoning…
The Bystander Effect and the murder of Kitty Genovese
Kitty Genovese: murdered on a public street (1964)
* Attack lasted over an hour
* Witnessed by more than 35 people (from upstairs windows overlooking the street)
* Not a single person helped, not a single person called the police
* Why?
The Bystander Effect
Diffusion of responsibility: we feel less compelled because we feel less responsible
Each bystander feels increasingly less responsible if there are many bystanders
We weigh the costs of helping as well as the benefits:
Physical danger weighed as well as psychological cost – i.e., being late if one stops to help
