Book
Forensic Psychology - A Very Short Introduction
Why this book
Forensic psychology is the discipline most people know best from television — profilers reading minds, experts testifying with certainty, criminal types neatly classified. David Canter's task is to correct that fictionalisation without dismissing the field. He is one of forensic psychology's founders (he coined the term "investigative psychology" in the UK), and his short book reads like a senior practitioner explaining what the discipline can and cannot do — measured, plural, often dryly funny.
The book's value is calibration. It tells you when a forensic psychologist is doing rigorous work, when they are performing for a courtroom, and when they are simply guessing. By the end, you should be a sharper consumer of every news story, court case, and crime drama you encounter.
What's inside
What it actually is
Forensic psychology = the application of psychology to the legal system, broadly construed. It covers everything from how criminals become criminals to how juries hear expert witnesses.
Making a criminal
Developmental and situational accounts — why most "criminals" are also victims, why most violent careers are short, and why the "born criminal" idea is bad science with persistent cultural pull.
In court
The expert witness — what they can legitimately offer (assessment, eyewitness reliability, false confession risk) and where adversarial systems push them past their evidence.
Legal proceedings
Memory, suggestibility, identification accuracy, jury decision-making — the empirical psychology of how the legal system actually works (and where it fails).
Working with offenders
Risk assessment, treatment, recidivism — the imperfect science of trying to change criminal behaviour and predict its recurrence.
With law enforcement
Offender profiling, interview techniques, geographic profiling — what works (rarely the Hannibal-Lecter stuff) and what is performance theatre.
Who it's for
- Curious general readers who want to know how much of CSI / Mindhunter / Silence of the Lambs is real.
- Law and criminology students who need the psychology context their core curriculum often skims.
- Practising lawyers, judges, and police who interact with forensic psychologists and want to evaluate their evidence more critically.
- Aspiring psychology students considering the field — Canter is honest about what the work actually involves day-to-day.
How to read it
The book is loosely sequential — earlier topics set up vocabulary for later ones — but each topic stands on its own:
- another topic (Excitement) is short and orienting. Skim it for the field's scope.
- The excitement and challenge of forensic psychology (Making a criminal) is the foundation. The developmental account here recurs throughout.
- How to make a criminal + 4 (Court / Legal proceedings) are a pair on what psychology contributes to the courtroom and where its limits are.
- 4 Psychology and legal proceedings (Offenders) turns to intervention and prediction.
- 5 Working with offenders (Law enforcement) is the topic most people skip to. Read the others first; otherwise the "profiling" framing is hard to evaluate.
- Working with law enforcement ("Always the bridesmaid?") is Canter's frank assessment of where the field stands relative to its sibling disciplines.
Author's stance
Canter is fond of the field and frustrated with its myths. He is more impressed by careful empirical work (his own and others') than by media-friendly profilers, and he is not above ribbing the discipline's pretensions. The book treats certainty as a warning sign and uncertainty as honest practice — which is the right frame for understanding what forensic psychology actually is.
