When people think about criminal cases, they often focus on the evidence. CCTV, witness statements, forensic reports. What is less discussed is the role the human mind can play in understanding behaviour, responsibility and intent.

While solicitors are not psychoanalysts, psychological insights can still be highly relevant in legal cases. Courts regularly rely on expert assessments to better understand a person’s actions, mental state and decision-making at the time of an offence. From a legal perspective, this information can influence how a case is approached, argued and, in some instances, sentenced.

This article looks at psychoanalysis in a legal context, how it differs from forensic psychology, and when psychological understanding becomes important in criminal proceedings. If you do need a criminal lawyer please get in touch with Broadbents Solicitors today!

Psychoanalysis is a way of understanding why people behave as they do, particularly when their actions are influenced by thoughts or experiences they may not be fully aware of.

It focuses on underlying factors such as past experiences, emotional triggers and unconscious thought patterns, rather than just outward behaviour. Trained clinicians use structured conversations to explore these influences over time.

In a legal context, psychoanalysis is not used to excuse behaviour, but to help explain intent, decision-making or mental state where this may be relevant to a case.

From a legal perspective, understanding criminal behaviour is not about justifying an offence. It is about identifying the factors that may have influenced how and why a decision was made.

Psychoanalytic thinking looks beyond the offence itself and considers issues such as impulse control, emotional responses, stress, trauma and long-standing behavioural patterns. In some cases, these factors may help explain why an individual acted in a way that appears irrational, impulsive or out of character.

In criminal proceedings, this kind of understanding can be relevant where intent, responsibility or risk is in question. It may also assist when presenting mitigation, particularly where personal history or mental state has played a role in the offence.

Courts do not rely on theory alone. Any psychological insight must be supported by qualified expert evidence and considered alongside the facts of the case. However, when used appropriately, it can provide important context that helps the court reach a fair and informed decision.

Impulsivity and Poor Decision-Making

Some offences are committed with little planning, often in moments of heightened emotion or stress. Impulsivity can affect a person’s ability to weigh consequences, particularly where anger, fear or pressure is involved. In legal cases, this may be relevant when assessing intent or explaining why an offence occurred in a short space of time.

Trauma and Past Experiences

Previous trauma, including childhood neglect, abuse or significant loss, can influence behaviour later in life. While this does not remove responsibility, courts may consider personal history when evaluating mitigation, especially where there is a clear link between past experiences and current behaviour.

Emotional Regulation and Stress

Difficulty managing emotions can play a role in offences involving aggression, confrontation or risk-taking. High levels of stress, anxiety or emotional instability may impair judgement and lead to reactions that escalate situations unnecessarily.

Patterned or Repeated Behaviour

Some individuals show repeated patterns of behaviour rather than isolated incidents. Understanding these patterns can be important when assessing risk, rehabilitation prospects and sentencing options.

Criminal behaviour does not always stem from long-standing patterns or personal history alone. In many cases, the situation a person finds themselves in can play a significant role in how they act.

High-pressure environments, sudden conflict, financial stress or fear can impair judgement and lead to decisions that would not normally be made in calmer circumstances. These situational triggers can interact with underlying psychological characteristics, increasing the likelihood of impulsive or risky behaviour.

From a legal standpoint, understanding the circumstances surrounding an offence is often just as important as understanding the individual involved. Courts may consider how events unfolded, whether there was provocation, and whether the behaviour was spontaneous or planned when assessing intent and culpability.

This approach recognises that criminal behaviour is often shaped by a combination of personal factors and external pressures, rather than a single cause.

Criminal behaviour is rarely driven by a single factor. It is often shaped by a combination of psychological characteristics, personal history and the circumstances surrounding an offence.

From a legal perspective, understanding what drives behaviour is not about justifying criminal conduct. It is about ensuring that intent, responsibility and risk are assessed fairly. Where appropriate, psychological insight, supported by expert evidence, can provide important context and assist the court in reaching a proportionate decision.

If psychological or behavioural factors may be relevant to a case, early legal advice is essential. A criminal lawyer can help identify when these issues should be raised and ensure they are properly considered within the legal process.
