B.A. LL.B. (Five Years) Sem 5 Criminal Psychology and Criminal Sociology Oct 2025 Question Paper with Solutions

For full marks, cover: the meaning of psychometrics and a psychological test; that no test measures "criminality" directly; the qualities of a good test (standardisation, reliability, validity, norms, resistance to faking); the kinds of test (objective inventories such as the MMPI, projective tests, intelligence tests, trait tests, risk assessment, neuropsychological tests); their role at each stage of the criminal process, with the Indian law (BNSS ss.367, 368; BNS s.22; JJ Act s.15); the leading cases (Manoj, Selvi, Hari Singh Gond); the limits and dangers; a table; and a conclusion.

1. Meaning

Psychometrics is the measurement of mental qualities. A psychological test is a standard set of tasks or questions, given and scored in a fixed way. The person's result is compared with the results of a large reference group, called the norms. The comparison shows where the person stands: higher or lower than most people on a given trait.

3. The kinds of psychological test

(a) Objective personality inventories. These are questionnaires answered "true" or "false", or on a scale, and scored by fixed keys. The leading example is the Minnesota Multiphasic Personality Inventory (MMPI).

1. Origin. It was developed at the University of Minnesota by Starke Hathaway and J.C. McKinley. Its first journal publication was in 1940.
2. Method. Items were kept if they separated groups with known clinical conditions from ordinary people, whatever the item seemed to be about.
3. The current version. The MMPI-3, by Yossef Ben-Porath and Auke Tellegen, was published in 2020. It has 335 true-false items and 52 scales, for adults aged 18 and over.
4. Validity scales. These detect careless, defensive or exaggerated answering.
5. Forensic use. Its publisher describes it as an assessment for "mental health, medical, forensic, and public safety settings".

4. The role of tests at each stage of the criminal process

(a) Investigation. Tests of intelligence and suggestibility show whether a witness or suspect is vulnerable in interview. A person of low intelligence may give a false confession under pressure.

(b) Fitness to stand trial. Under BNSS sections 367 and 368, an accused who appears to be of unsound mind is referred to a "psychiatrist or clinical psychologist". The expert reports whether he suffers from unsoundness of mind or intellectual disability. Psychological tests form part of that assessment.

(c) Criminal responsibility. BNS section 22 excuses a person who, "by reason of unsoundness of mind, is incapable of knowing the nature of the act". Tests help the expert describe the accused's mental state. But the court decides the legal question.

Hari Singh Gond v. State of Madhya Pradesh, (2008) 16 SCC 109. The Supreme Court said the court "is concerned with legal insanity, and not with medical insanity." A test result is therefore evidence for the court, not a verdict.

5. Tests are not lie detectors

Psychometric tests measure traits. They do not detect lies or prove guilt. The techniques that claim to do so, such as the polygraph, narco-analysis and brain mapping, face strict legal limits.

Selvi v. State of Karnataka, (2010) 7 SCC 263, decided 5 May 2010. The Supreme Court held that "the compulsory administration of the impugned techniques violates the 'right against self-incrimination'" under Article 20(3). Results obtained through compulsion cannot be admitted. Voluntary tests are allowed only under the NHRC guidelines. The case marks the line between psychological assessment, which is lawful, and forced extraction of information, which is not.

6. Limits and dangers

1. Prediction is imperfect. Even good risk tools misclassify many people. They falsely label some as dangerous and miss others.
2. Cultural bias. Tests developed abroad may not suit Indian languages, cultures and education levels unless adapted and normed locally.
3. Faking and coaching. Offenders have reasons to present themselves in a particular way.

Conclusion

Conclusion. Psychometric testing measures mental characteristics against norms. It cannot measure "criminality" itself, but it can measure the personality, intelligence, mental state and risk that the law needs to know about. A good test is standardised, reliable, valid, properly normed and resistant to faking. The MMPI is the best known, alongside projective, intelligence, trait, risk and neuropsychological tests. Indian law now uses such assessment in fitness to stand trial, juvenile cases and sentencing, as Manoj requires. But Hari Singh Gond and Selvi show the limits. A test is evidence for the court, and no test may be forced on a person to extract the truth.
