Evaluation: Factors Influencing Jury
Decision Making
- Characteristics of the defendant
- Attractiveness
- It is suggested that attractive defendants
are treated more favourably by juries
Than less attractive ones. Abwender and
Hough aimed to investigate this idea, as
well as to see whether this effect was
dependent on the sex of the jurors.
- They found that female participants were more
lenient towards an attractive female
defendant, and less lenient towards an
unattractive defendant. Male participants
showed the opposite tendency.
- However, results of supporting studies are often contradictory and
inconsistent. Patry found that mock jurors that discussed the case were
more likely to find an attractive defendant guilty guilty whilst those that
discussed less were more likely to find a plain defendant guilty. These
results are opposite to Abwender and Hough's findings. Therefore, the
effect of attractiveness on the decision-making process may vary
depending on other factors, which makes firm conclusions difficult to
gather.
- Race
- It is suggested that the
ethnic group of the
defendant matters in
regard to jury decision
making.
- Bradbury and Williams analysed data from real-life criminal cases
in the USA and found that juries comprised of predominantly white
jurors were more likely to convict a black defendant, followed by
juries made up of mainly hispanic jurors. In both cases, this was
more marked for certain crimes, such as drug offences.
- Pfeifer and Ogloff found in their study
that participants overwhelmingly
rated black defendants more guilty
than white defendants, especially
when the victim was white.
- Accent
- The accent of a
defendant is also
said to influence the
decision a jury
makes.
- Dixon et al found that ratings of guilt were
significantly higher when participants heard a male
suspect with a Birmingham accent than a suspect with
a 'standard British' accent, suggesting that accent is
another factor that influences the decision a jury
makes.
- Pre-trial publicity
- Pre-trial publicity includes news coverage on
TV and in other parts of the media of certain
criminal cases. It is suggested that pre-trial
publicity can influence peoples' opinions
based on the often biased information
presented in the media, which can influence
the decision of the jury (who are supposed to
decide whether a defendant is guilty or
innocent based on the information presented
in the courtroom alone.
- Steblay reviewed past research and found that those
exposed to more negative pre-trial publicity were
significantly more likely to be found guilty than those
who did not. This supports the idea that pre-trial
publicity, particularly negative publicity, can influence
the decisions of a jury.
- The OJ Simpson case was highly
publicised, and this made it
extremely difficult to find a jury that
did not already hold any of their
own views prior to the trial, which
could have led to a biased
conviction/release.
- A strength of the research into these factors is that most of it is ethical. The
use of mock-juries in the majority of these studies allows the researchers to
manipulate variables which would not be practical or ethical to do in a real
case. Cases also use secondary data, and looks at cases which have already
occurred so these also do not have ethical implications. This means that the
factors can be tested without prejudicing the outcome of real trials.
- However, as they are mock juries and
trials, the results of these studies may lack
ecological validity.
- A weakness of research into this area is that there are many
untested factors which could influence jury decision making. Other
factors that could influence the results of the studies supporting
these ideas include jurors having personal experiences of the crime,
whether there are charismatic leaders on the jury who can sway
opinions, or whether characteristics of the jurors match the
characteristics of the defendant, perhaps creating more empathy.
The failure to recognise these potential factors limits the usefulness
of results coming from mock or real trials.
- The research into factors that could influence jury decision
making can be applied to real life court systems. For
example, jurors should be reminded that they need to
remain impartial as the research has shown that jurors are
humans who are all subject to biases which could impact the
neutrality of the verdict. This knowledge of jury biases could
help reduce the miscarriage of justice in the future.
