Introduction
Forensic psychology and forensic psychiatry sit at the intersection of mental health and law. They address questions of the human mind, behaviour, criminal responsibility, and legal competency. While both fields are interlinked, they differ in their origins and roles: forensic psychology stems from psychology and behavioural sciences, whereas forensic psychiatry is rooted in medicine and clinical psychiatry.
Definition & Scope
Forensic Psychology involves the application of psychological theories, methods, and expertise to the legal and criminal justice system. It includes criminal profiling, competency evaluations, risk assessments, counselling for victims and offenders, jury selection assistance, and providing expert testimony in court.
Forensic Psychiatry, on the other hand, is a medical specialty where psychiatrists assess, diagnose, and treat mental disorders within the legal context. Their expertise is critical in determining criminal responsibility (insanity defence), fitness to stand trial, and involuntary treatment.
Key Areas of Practice
1. Competency to Stand Trial
A fundamental issue is whether an accused is mentally fit to understand the court proceedings and assist in their defence. This competency is determined by forensic psychiatrists and psychologists through structured interviews and standardized tests (e.g., MacArthur Competence Assessment Tool).
Reference: Dusky v. United States, 362 U.S. 402 (1960) — established the modern standard for competency in the US.
2. Criminal Responsibility and Insanity Defence
Courts often require expert opinions on whether the accused was sane at the time of the offence. The McNaughten Rule (UK) and Section 84 of the Indian Penal Code are classic doctrines that hinge on the defendant’s ability to know the nature or wrongfulness of their act.
Landmark Indian Reference: In Surendra Mishra v. State of Jharkhand, (2011) 11 SCC 495, the Supreme Court reiterated the importance of proving legal insanity, not just medical insanity.
3. Risk Assessment
Forensic psychologists assess the likelihood of reoffending (recidivism) through structured risk assessment tools (e.g., HCR-20 for violence risk). These assessments help courts in sentencing, bail, parole, and treatment planning.
4. Profiling and Behavioural Analysis
Criminal profiling involves inferring an offender’s characteristics from crime scene evidence. While popularized by the FBI’s Behavioral Analysis Unit (BAU) and media like Mindhunter, profiling is more an art than an exact science and has been criticized for its subjective nature.

5. Victimology and Trauma Psychology
Experts work with victims of crime, including children and survivors of sexual violence, to assess psychological trauma, provide therapy, and prepare them for testimony. Courts may rely on trauma psychologists to understand delayed disclosures or inconsistencies in witness statements.
6. Juvenile Justice & Rehabilitation
In juvenile courts, forensic psychologists evaluate whether a young offender can be rehabilitated or should be tried as an adult. They design intervention plans, counselling, and community reintegration programmes.
Methods & Tools
- Psychometric Tests: MMPI-2 (Minnesota Multiphasic Personality Inventory), WAIS (Wechsler Adult Intelligence Scale)
- Clinical Interviews: Structured interviews following DSM-5 or ICD-10 diagnostic criteria.
- Neuropsychological Tests: Assessing brain damage or cognitive impairments.
- Behavioral Observations: In custody or controlled settings.
Key Challenges
- Ethical Dilemmas: Forensic experts balance their duty to the court with obligations to the client. Confidentiality is limited in forensic settings.
- Reliability: Critics argue that some techniques, like profiling or lie detection, lack empirical support.
- Bias: Confirmation bias and adversarial allegiance can affect expert neutrality.
- Wrongful Convictions: Overreliance on flawed psychological testimony has contributed to miscarriages of justice.
Example: In the Central Park Five case (US), coerced confessions and misleading psychological tactics led to wrongful imprisonment.
Indian Context
In India, forensic psychiatry is underdeveloped compared to Western jurisdictions. Few institutions like the National Institute of Mental Health and Neurosciences (NIMHANS) Bengaluru, or Institute of Human Behaviour and Allied Sciences (IHBAS) Delhi, offer specialized forensic services. Indian courts are increasingly relying on mental health experts for high-profile insanity pleas or in death penalty cases where mental illness may be mitigating.
Example: In Shatrughan Chauhan v. Union of India (2014) 3 SCC 1, the Supreme Court commuted death sentences of mentally ill prisoners, underscoring the importance of forensic psychiatric reports.
Future Directions
- Integration with Neuro-Law: Advances in brain imaging and neuroscience are influencing legal questions about free will and criminal responsibility.
- Trauma-Informed Courts: Growing focus on victim psychology and trauma-informed prosecution.
- AI & Psychology: Use of artificial intelligence to detect deception or mental health patterns.
- Training & Accreditation: Need for standardized training for forensic psychologists in India.
Conclusion
Forensic psychology and psychiatry are indispensable to modern criminal justice. They provide courts with scientific insight into the human mind, motivations, and culpability. However, they must evolve with stricter standards, empirical validation, and robust ethical safeguards to ensure that justice is truly served — not undermined by flawed science.
