Title: Social influence
1Social influence
- Three main types of social influence
- Compliance behavior change based on a request
- Conformity behavior change based on social
pressure - Obedience behavior change based on instruction
from an authority
2Compliance
- Q How do we convince people to comply with our
requests? - A Ask for a small favor, before asking for the
big favor you really want - Franklin was annoyed by a political opponent in
the Pennsylvania state legislature. He thus set
out to win him over, as described in one of his
books - I did not ... aim at gaining his favour by paying
any servile respect to him but, after some time,
took this other method. Having heard that he had
in his library a certain very scarce and curious
book I wrote a note to him expressing my desire
of perusing that book and requesting he would do
me the favour of lending it to me for a few days.
He sent it immediately and I returned it in about
a week with another note expressing strongly my
sense of the favour. When we next met in the
House he spoke to me (which he had never done
before), and with great civility and he ever
after manifested a readiness to serve me on all
occasions, so that we became great friends and
our frendship continued to his death. This is
another instance of the truth of an old maxim I
had learned, which says, "He that has once done
you a kindness will be more ready to do you
another than he whom you yourself has obliged."

3Why does it work?
- Cognitive dissonance
- Contradictions feel uncomfortable. Thus,
- People aim to reduce their contradicting feelings
- How do we reduce our contradicting feelings?
- Change our behavior (Franklin, gimme back my
book, you asshole!) hard - Change our attitude Benny is ok. Much easier
4- Other examples of cognitive dissonance
- Hazing lots of effort to get there, Id better
like it. - Fraternities
- Military
- Experimental evidence
- - If I have a compelling reason for my effort
(they paid me a shitload of ) - - there is no dissonance gt I judge the event
accurately (it was hell)
5Other cases of cognitive dissonance
- COUNTER-ATTITUDINAL ADVOCACY when we state
opinions we don't believe, we start to believe
them (Festinger, 1959, Aronson 1991 aids speech) - LABELING When told something is certain way, we
modify our behavior to match that description
(trash collection by 5th graders) -
6Compliance
- foot-in-the-door If you agree to a small
request, you are more likely to agree to a larger
request - Charities contribute even if it is 1
- Experimental evidence (Freedman Fraser, 1966)
- - control condition
- post an ugly sign drive carefully 17
agreed - - experimental group
- sign petition about driving safely promotion
- post an ugly sign drive carefully 76
agreed - door-in-the-face If you decline a large
request, you are more likely to agree to a small
request
7Compliance
- Thats-not-all you are more likely to comply if
you give them something in addition to the
initial offer - NPR drive donateyoull also get a DVD of The
American Experience - Bait-and-switch Once you made a commitment, you
are unlikely to back out when the conditions

8Conformity
- Conformity behavior change because of social
pressure - Which line is the same length as the target?
(Asch, 1950s)
Target A B
C
9- Subjects were tested in groups
- - only one real subject, the rest are
confederates - For the first few trials, everyone answers
correctly - Then, confederates start giving the same wrong
answer (uniformity) - Results the subject often conformed with the
group - Factors that reduce conformity
- A dissenting confederate
- Answer privately
- Factors that increase conformity
- - Situation is ambiguous
- - Situation is a crisis
10-
- Conformity influences on helping behavior
- diffusion of responsibility - reduction in
perceived individual responsibility, due to
presence of other people. - 2 reasons
- - self-serving interests
- - informational component
11- normative influence- desire to be liked, accepted
and approved of - informational influence- desire to be correct,
and understand how best to behave. - Factors affecting likelihood of conformity
- - Size of the group
- (3 is the magic number!)
- - Importance of the group
- - Unanimity of the group

13- The confederate responds in the following manner
to the shocks
voltage confederate response
75 grunts
120 shouts in pain
150 says that he refuses to continue with this experiment
200 blood-curdling screams
300 refuses to answer, mumbles something about a heart condition
330 silence
As the participant perceives the confederate's
pain, his conscience kicks in, and he begins to
object to continuing the experiment. Milgram
responds to these objections in the following
way
objection milgram's response
first "He's fine. go on."
second "The experiment requires you to go on."
third "It is absolutely essential to go on."
fourth "You have no choice. You must go on."
Question What percentage of participants would
deliver the full 450 volts? Milgram asked his
colleagues this question, and they responded with
very small estimates. Maybe about 4 percent.
Milgram himself didn't believe anyone would go so
far.
Experimental Results
Milgram's results were alarming. Of the 40 participants he surveyed, 68 of them ended up delivering the full 450 volt treatment. 15 of the 40 ended up convulsing with epilpetic laughter. Participants went temporarily mad and started tearing their hair out. Most amusingly, Milgram actually believed that the aforementioned experimental setup was the CONTROL case! He did not anticipate that subjects would conform at all in these conditions.
Right Maximum shock voltage delivered by each of the 40 participants. Mode is XXX.Below Shows how participant compliance slowly decays as voltages increase. 68 complied till the end!
Milgrams experiment When shocked, the
confederate gives the following standard response

- Explanation
- Situationism gt The moral of Milgram's experiment
is that behavior is not just a function of
personality, but also a function of the situation
-- and the latter variable can possess dramatic
weight. The bullets directly below detail aspects
of Milgram's fabricated environment which made it
most persuasive. - Entrapment / Gradual Commitment gt If I just gave
him a 50 volt shock, what's wrong with a 75 volt
shock? It's only a little more. If I just gave
him a 75 volt shock, what's wrong with a 100 volt
shock? It's only a little more ... If I just gave
him a 425 volt shock, what's wrong with a 450
volt shock? People can be entrapped into
fulfilling ridiculous requests if you just ask
them to commit gradually. Mating is another
example of entrapment. First you go out for
coffee, then you go on a few more casual dates,
then you watch TV together, then you make out,
and then before you know it, you get married. - Objectivity gt Milgram told participants that the
"learning" experiment was being conducted in the
pursuit of science, to study how memory and
learning processes work in humans. The scientific
theme, combined with the prestige of Yale
University and the nontrivial influence of
Milgram's lab coat, suggested that participants
calmly and objectively complete the study
regardless of how the victim was suffering. Do it
scientifically. Do it like professionals. - Authority Structures gt Milgram played the
authority figure. It was his experiment.
Participants thus believed that any negative
ramifications of the experiment would ultimately
be blamed on Milgram and not themselves.
Furthermore, Milgram was a scientist at Yale. So
particpants assumed that he probably knew what he
was doing, and everything was going to be
alright. Authority structures strip away moral
responsibility.
- Mainpulating Obedience Methods That Don't Work
- Reduce Prestige (48) gt The same experiment was
conducted at a less prestigious school called
Bridgeport. 48 of participants still gave the
full 450 V shock. - Soften Personality of Authority Figure (50) gt
Milgram was a tall, stern, imposing figure with a
severe haircut. The experiment was repeated with
nicer experimenters. 50 of the participants
still gave the full 450 V shock.
- Mainpulating Obedience Methods That Do Work
- Reduce Legitimacy of Authority Figure (20) gt
Here there are two confederates one assigned to
be the learner, and another who assists the
participant in the "teaching" process. Shortly
after the participant arrives, Milgram says he's
got something else to do, and asks the
participant and teaching confederate, "Why don't
you two just finish the experiment yourself?"
Milgram leaves. The loony teaching confederate
then says that he's got a great idea let's shock
the learner when he gets things wrong! 20 of
participants deliver maximum voltage.One way to
look at this is as a very positive change. We
went from 68 compliance to 20. But the other
way to look at this is with awesome fear. 20 of
us will actually blast away another person if a
random guy on the street tells us to! - Increase Distance From Authority (20) gt When the
authority figure is no longer standing next to
the participant, but rather sends commands via
telephone, 450 V compliance drops to 20. This
phenomenon is also frequently observed in army
battles. During WWII, soliders in trenches would
fight very cooperatively with their enemies when
commanding officers were far away. One side would
fire some initial pot-shots to warn the other
side to hide. Then they would shoot a little bit,
and quickly return to their trenches. The other
side then did the same. Repeat. No one gets hurt!
And since the commander isn't there, you can get
away with it. - Decrease Distance From Victim (30) gt When
participants are required to put the learner's
hands on the shock plates, or are simply placed
closer to the victims, 450 V compliance drops to
30. Reducing the distance amplifies
participants' perceptions of the confederate's
pain, stinging their empathy.Another example of
this effect occured during the Holocaust. The
original master plan did not involve large-scale
incinerators and gas chambers, but instead asked
that Nazi soldiers be responsibile for rounding
up particular families and killing them. This
resulted in widespread mutiny and alcoholism
among SS soldiers, because they couldn't handle
seeing the pain of their victims up close. - Add Dissenting Voices (37.5) gt Two confederates
assist the participant. One reads a word. Another
determines whether the "learner" responds
correctly. Finally, the participant is
responsible for delivering the shock. At the 150
V mark, the first confederate quits the
experiment. At the 210 V mark, the second
confederate also quits, leaving the participant
with sole responsibility for the shock
treatement. 25/40 participants leave at this
point.These results are testimony to the power
of dissenting voices, and provides insight as to
why some dictators throughout history have been
so tenacious about eradicating all dissent in
their jurisdiction, even in its slightest, most
innocent form. An example is Stalin, who deleted
everyone who disagreed with him in any way.
14 15Obedience What can we learn from Milgrams
experiment?
- The power of Situations. behavior is not just a
function of personality, but also a function of
the situation - Gradual Commitment gt It is just a little more
than the previous one - Politicians corruption
- Truman nuclear bombs in WWII
- Influence of Authority gt
- Science authority (white coat, Yale U., do it
in the pursuit of science) .
16- Manipulating Obedience What Does Work
- Reduce Legitimacy of Authority Figure (20) gt
Milgram has an assitant, and it is the
assistant who, soon after Milgram leaves, says
I have a great idea let's shock the learner when
he gets things wrong! (only 20 go to max V, a
48 drop) - Increase Distance From Authority (20) gt When
Milgram instructs via a phone, - Decrease Distance From Victim (30) gt When
participants are required to put the learner's
hands on the shock plates, - Add Dissenting Voices (37.5) gt Two confederates
assist the participant, but quit at 150 V mark
and at 210 V mark.. 25/40 participants leave at
this point.
17- Manipulating Obedience What Doesn't Work
- Reduce Prestige gt Replicated at a less
prestigious (fake) school named Bridgeport (48
went to max V) - Soften Personality of Authority Figure gt
Replicated with nicer experimenter (not so stern)
(50 went to max V) -
18- How can you live with yourself, after doing that?
- Transfer of responsibilities
- I was just following orders Abu Graib,
Argentinas dirty war - Cognitive reinterpretation
- Dehumanize the victim (its his fault) he must
have done something
