Forensic, Legal, and Risk Psychology
Psychology in Legal Systems
Why Legal Contexts Are Special
Legal settings demand high-stakes judgments under adversarial incentives. Applied psychologists contribute to interviewing, competence evaluation, risk assessment, testimony, and system design, but must account for bias, memory limits, and ethical constraints.
Common Applied Domains
Eyewitness Memory vs Recorded Evidence
Eyewitness reports
- Prone to reconstruction and suggestion
- Can be valuable when corroborated
- Should be elicited with best-practice interviewing
Recorded evidence
- Less vulnerable to memory distortions
- Still requires interpretation
- May omit context and meaning
Caution
Confidence does not equal accuracy; a witness may be sincere and wrong.
Which statement about eyewitness memory is most accurate?
Memory is reconstructive and can be influenced by post-event information.
Correct answer: Suggestion can alter recollection
Why must risk assessment be used carefully in legal contexts?
High-stakes decisions require humility about uncertainty and base rates.
Correct answer: Because predictions are probabilistic, context-dependent, and vulnerable to bias and false positives.
Best-Practice Forensic Interviewing
-
1
Step 1: Use open-ended prompts first.
-
2
Step 2: Avoid leading questions and feedback.
-
3
Step 3: Separate free recall from recognition questions.
-
4
Step 4: Document confidence, timing, and source of information.
-
5
Step 5: Corroborate statements with independent evidence whenever possible.
The biggest problem with using unstructured gut feeling for legal risk prediction is that it often:
Actuarial and structured approaches usually outperform unguided intuition.
Correct answer: Ignores probabilistic evidence and introduces bias
