Asch (1955) showed how a
single PP in a group would
conform to the majority
Hastie (1983) found that
a jury's final verdict
reflected the view held
by the majority of jurors
86% if the final decision was
innocent, 90% if it was guilty
normative influences
wanting to be
accepted by the
group
informational
influences
being affected by
believing that
others know better
Smith and Mackie (1995)
suggested several reasons
why the majority is so influential
Varied
opinions
being the majority, they can
express their opinion in a
variety of ways
however, Hinsz and Davis (1984)
found the more varied the opinions,
the greater the shift in opinion
Deeper
discussions
shared discussions can be
longer with more people
however, Stasser and Stewart (1992) found
that even when instructed to discuss all the
information, the PP's focussed almost entirely
on the shared information and virtually
excluded all the non-shared information
Greater
confidence
knowing most people share the same views,
allows members to be more convincing and are
more likely to convert others
Kerr (1987) claimed knowing more people are on your
side allows majority members to be more
argumentative, so their views are more compelling
Minority Influence
Nemeth (1977) says minority
makes the majority question
their own opinion
Attribution
effect
Attribution theory; their behaviour is seen to be
motivated by a deep conviction since they are
defending and therefore we attribute their beliefs to
internal, dispositional causes rather than external ones
Moscovici (1969) demonstrated
the power of the minority
In trials with 50% confederates, the
conform rate of PP's was 1.25% but
rose to 8.42% when the confederates
answered incorrectly consistently
Moscovici suggests that individuals in
juries can change the majority view
when they have a long deliberation
period, but they need to be consistent
however, Tindale (1990)
- for the minority to have
an effect, they must be in
large groups
Characteristics of
the defendant
Juror's beliefs about the defendant
will affect their decision making
Dixon (2002) asked PP's to
judge guilt from a recorded
exchange between a
suspect and policemen
standard british accent =
rarely identified as guilty
Birmingham accent =
significantly more likey
to be guilty
Ethnicity
Stereotypes based on ethnicity
affect jurors' decision making
Duncan (1976) varied ethnic group
of the perpetrator and victim in a
tape of a potential violent situation
PP's judged shove as more violent
when done by a black individual
Pfeifer and Ogloff (1991) found in
a mock jury case that white PP's
were more likely to judge a black
defendant guilty in a rape case,
especially when
victim was white
when asked to justify verdict, the
effect of ethnicity disappeared
suggests that differences were due
to stereotyping
however, Mazzella and
Feingold (1994) found no
overall effect of ethnicity
on mock jury decisions
Judgements of ethnic
minorities are similarly
biased in real cases
Baldwin and
McConville (1979)
found that black
defendants were more
likely to be wrongly
convicted
even if members of
the jury were black
however, Gordon
(1988) found that
longer sentences
were given to white
people if the crime
was fraud
Physical Attractiveness
In court we tend to link
physical attractiveness with
positive characteristics
Saladin (1988) showed
PP's photos of men and
asked them to judge how
capable the men were at
committing a crime
found that attractive men
were considered less likely
to commit a crime than the
unattractive ones
it's the same with sentencing
DeSantis and Kayson (1997) found
that mock jurors gave unattractive
defendants harsher sentences
however if attractive
individuals appear to be
abusing their good looks
then the advantage is lost
Sigall & Ostrove (1975)
found unattractive defendants
were given longer sentences
for burglary but the reverse
was true for fraud
Downs and Lyons demonstrated
a negative correlation between
defendant attractiveness and
fines/ bail payments
however, attractiveness
seems to be irrelevant
when imposing fines /
setting bail payments
(McKelvie and Coley, 1993)
