Q

what are two biological strategies to prevent crime?

A

plastic surgery
drug treatment

20
Q

why would plastic surgery work to prevent crime?

A

correct facial defects
associated with physical abnormalities with criminality
exposed to ugly villains and handsome princes
self esteem independently linked to risk of criminality

21
Q

what study used plastic surgery to reduce crime?

A

lewinson
450 facial reconstructions for prisoners broken noses, facial scars, deformed ears
increased cooperation with authority and prison activities
inmates likely to learn a trade

22
Q

what are strengths of plastic surgery to prevent crime?

A

reduces recidivism
enhances self esteem and perception
improves reputation and first impressions
breaks sfp ’new start’
42% reoffend not 75

23
Q

what is a weakness of plastic surgery to prevent criminals?

A

reductions
not all crime
not all criminals need

24
Q

issues with crime scenes and fingerprints

A

mistake made with fingerprints
golden hour
Competing motives
-motivated to identify criminals
-motivated to catch the right criminals

25
Q

what are motivating factors and bias with fingerprints?

A

Charleston- 13 analyst main motivation
rewards
hope and satisfaction
case importance
feelings
-marks often poor quality, incomplete, sludge, distracted

26
Q

what are problems with fingerprint analyst Dror?

A

lack of consistency
individual fingerprint analyst from one another and themselves over time
-range of cognitive factors bias decisions

27
Q

what are causes of bias in fingerprint analyst?

A

-emotional context: Dror- high emotion increases chance of match decision
-desire to solve the case: when matched prints found- motivated to find more non existent

28
Q

what are latent marks?

A

marks left by fingerprints on surfaces, ridges and patterns

29
Q

what are Hall and players aims?

A

-if fingerprint experts emotionally affected by case details in report
-if emotional context would bias the decisions

30
Q

what was Hall and Player sample?

A

70 experts
Met police bureau
volunteers
11 years mean experience

31
Q

what was the design for hall and player?

A

lab experiment
independent measures design
IV- high emotion- fire two shots
low emotion- forgery fake £50
DV-impacted by emotional context and if it effected decision

32
Q

what fingerprint where they given in Hall and Players study?

A

-fingerprint from known source
-superimposed- latent mark only just identifiable (confirmed by other experts)
-matched set of 10 donor prints
-colour, size and detail valid

33
Q

what two objects were the analysts given?

A

-fingerprint magnifying glass
-Russell comparator

34
Q

what were the analysts given in hall and players study?

A

-test mark card
right forefinger
examiners report
10 fingerprints

35
Q

what were the results for hall and players study?

A

high emotion affected- 50%
low emotion- 6%
-no significant difference between decisions made identified 6 highs, 7 low

36
Q

what were the conclusions for hall and players study?

A

-emotional context affects expert feelings
-doesn’t affect analysis/ decision
-experts better at analysing

37
Q

what are application for fingerprint analysis?

A

-independent analysis of prints
-Filler- control method
-working in isolation from other evidence

38
Q

what is independent analysis of prints?

A

-Kassin-linear approach
analyse print in isolation
analyse comparison print
compare
reconsider original analysis

39
Q

what is the issue with not using independent analysis of prints?

A

low inter-rater reliability (Dror)
-comparison print set up cognitive expectations
affects analyst attention search for only similarities

40
Q

what are strengths of using independent analysis?

A

mitigates impact of cognitive expectations improves objectivity

41
Q

what are weaknesses of independent analysis?

A

-time consuming
-may not be possible in all circumstances

42
Q

what is the filler control method?

A

6 comparison prints to remove motivation to match print to suspect
-drives competing motivation to find right criminal (Dror)

43
Q

what are strengths of filler control method?

A

-increases validity and accuracy in finding criminal

44
Q

what are weaknesses of filler control method?

A

-time consuming
-where do the prints come from

45
Q

what is isolation from other evidence?

A

Kassin- unaware of crime scene info
-Hall + Player- info can influence and impact cognitive decisions
-verification should also be blind

46
Q

what is a strength of isolation from other evidence?

A

-reduces psychological harm
-reduces emotional bias

47
Q

what are weaknesses of isolation from other evidence?

A

-difficult to implicate
people talk/ news
can’t always be unaware
