Psychology and Law

Laws

• Laws are human creations intended to maintain order, consistency, and resolve conflicts in society.
• They serve as mediators between individual impulses and societal rights.
• They are not static and evolve with societal changes, technological advancements, and changing norms.

Psychological Study of Law

• Emphasizes the influence of both personal traits and environmental factors on behavior within legal contexts, based on Kurt Lewin's B=F(p,e) model.
• Focuses on the individuals within the legal system such as jurors, defendants, and judges.
• It has evolved from informal systems of vigilante justice to structured legal systems.

Psychology of Law

• Examines how all citizens actively participate with laws daily.
• It studies the roles of various participants, including defendants, witnesses, lawyers, judges, juries, convicts, and parole boards.
• Forensic psychologists, often clinical psychologists, play a key role in legal evaluations and disputes.

Basic Choices in the Psychological Study of Law

• There is a need to balance personal freedoms with societal protection (e.g., smoking regulations, Miranda rights).
• The due process model focuses on protecting individual rights and ensuring fair treatment.
• The crime control model emphasizes crime reduction and efficient law enforcement
• The principle of equality states that similar crimes should receive similar punishments.
• Discretion allows for flexibility in sentencing depending on the judge, but this can lead to disparities due to implicit biases.
• Determinate sentencing reduces judicial discretion, though it can be unpopular.
• Procedural justice suggests that fair procedures can enhance perceptions of justice.
• Plea bargaining and settlement negotiations demonstrate the importance of conflict resolution over absolute truth.
• Therapeutic jurisprudence focuses on rehabilitation (e.g., drug courts).
• Science relies on empirical data and probabilities, while law depends on precedents (stare decisis) and absolute judgments.
• Psychologists provide scientific insights to courts through amicus curiae briefs.

Psychologists’ Roles in the Legal System

• Forensic evaluators assess defendants and provide expert testimony.
• Consultants assist in jury selection, trial strategy, and legal reforms.

The Adversarial System

• The US legal system involves parties presenting evidence to persuade an impartial fact-finder (judge/jury).
• The inquisitorial system (used in Europe) involves judges leading investigations, making it less adversarial.
• The adversarial systems can distort truth, but it may promote fairness and reduce bias.

Legality vs. Morality

• Black-letter law refers to clear legal statutes.
• Laws may conflict with public moral beliefs (e.g., euthanasia), creating moral dilemmas.

Intention in Law and Psychology

• Attribution theory explains how people assign causes to behaviors, which influences perceptions of culpability.
• Dimensions of attribution include internal/external, stable/unstable, and global/specific factors.

Justice Concepts

• Distributive justice emphasizes fairness in outcome distribution
• Procedural justice emphasizes fairness in legal processes.
• Commonsense justice defines laypeople’s perceptions of fairness, which often differ from formal law.
• Jury nullification occurs when jurors acquit despite legal guilt due to moral objections.

Courts

• State courts handle most criminal/civil cases and are structured into lower, trial, and appellate courts.
• Federal courts include US District Courts (trial), US Courts of Appeals, and the US Supreme Court.
• The US Supreme Court reviews cases with constitutional/federal implications; justices are appointed by the President.

Legal System Players

• Judges can be appointed or elected; their decisions are influenced by personal experiences and systemic structures.
• Decision-making is influenced by legal formalism vs. legal realism, as well as cognitive biases and intuitive processes.
• Lawyers include prosecutors, defense attorneys, corporate lawyers, and government attorneys.
• Public defenders represent indigent defendants (Gideon v. Wainwright).
• Lawyers face high intellectual demands and varying job satisfaction.

Legal Education

• Law school can cause a shift from intrinsic to extrinsic motivation, which can impact mental health.
• Self-determination theory explains changes in motivation and well-being.

Professional Satisfaction Among Lawyers

• Work-life balance challenges involve high stress and competitive environments.
• Minority lawyers face unique challenges but view law as an opportunity.

Decision-Making in Law

• Therapeutic jurisprudence refers to legal practices that promote psychological well-being.
• Motivated reasoning can cause judges/lawyers to unconsciously favor certain outcomes.

Steps in the Criminal Justice Process

• Investigation: Law enforcement gathers evidence through interviews, surveillance, and forensic analysis.
• Arrest: Based on probable cause and a warrant, unless exigent circumstances exist.
• The initial appearance involves informing defendants of charges and setting bail.
• A preliminary hearing or grand jury determines if there is sufficient evidence to proceed to trial.
• At the arraignment defendants enter a plea (guilty, not guilty, or no contest).
• The trial involves prosecution and defense presenting evidence, with a verdict rendered by a judge or jury.
• If convicted, the judge imposes a penalty based on statutory guidelines.
• Appeals can be made to review trial procedures for legal errors.

Rules of Evidence

• Relevance: Evidence must directly relate to the case.
• Admissibility: Judges decide what evidence can be presented based on exceptions like hearsay.
• Reliability: Scientific evidence must meet standards like the Daubert criteria (validity, peer review, error rates).

Psychological Aspects of Investigation

• Eyewitness Testimony: Subject to memory distortions, stress effects, and suggestibility.
• Interrogation Techniques: Can lead to false confessions, especially with coercive methods.
• The Reid technique is criticized for increasing false confession risks.
• The PEACE model emphasizes ethical, non-coercive interviewing.

Jury Selection (Voir Dire)

• The process by which attorneys question potential jurors to assess biases
• Challenges for cause are used to remove jurors with obvious biases.
• Peremptory challenges are a limited number without stating a reason, though not based on race/gender (Batson v. Kentucky).

Trial Procedures

• Opening statements outline each side’s case.
• Presentation of evidence includes witness testimony, cross-examinations, and physical evidence.
• Closing arguments summarize key points, aiming to persuade the jury.
• Judges provide jury instructions to explain legal standards jurors must apply.

Verdicts and Sentencing

• Jury deliberations: Confidential process to reach a unanimous or majority verdict, depending on jurisdiction.
• Sentencing factors: Crime severity, defendant’s history, mitigating/aggravating circumstances.
• Alternative sentencing: Probation, community service, and restorative justice programs.

Appeals Process

• Grounds for appeal: Legal errors, juror misconduct, and ineffective counsel.
• Appellate courts: Review records, legal briefs, and may hear oral arguments.
• Outcomes: Affirm, reverse, or remand cases for retrial.

Role of Police

• The most visible part of the justice system.
• Police confront criminal activity directly through patrol, investigation, and enforcement.
• They must balance crime prevention with respect for constitutional rights while maintaining public trust and ensuring safety.

Challenges Faced by Police

• Overwork, exposure to dangerous situations, and high-stress environments.
• Susceptibility to corruption, ethical dilemmas in the use of force, and decision-making under pressure.
• Public trust issues, especially concerning treatment of minority communities and allegations of bias or brutality.

Selection of Police Officers

• 1916: Introduction of intelligence testing by Lewis Terman (recommended IQ > 80).
• 1960s–1990s: Growth of formal psychological assessments to screen for mental fitness and emotional stability.
• Evaluation methods include structured interviews, situational tests, and psychological tests (e.g., MMPI-2-RF, Inwald Personality Inventory).
• Structured interviews improve reliability by standardizing questions and assessing communication skills, judgment, and ethical reasoning.
• Situational tests simulate real-life scenarios to predict performance in high-stress situations.
• Less common due to cost and resource demands.
• Psychological tests measure cognitive abilities, personality traits, and emotional stability (e.g., MMPI-2-RF, Inwald Personality Inventory).

Training

• Police Academy: 14-24 weeks, approximately 40 hours per week.
• Curriculum includes criminal law, firearms training, defensive tactics, emergency response, and ethics.
• Some academies require college credits or prior educational qualifications.
• Criticisms include few trainees failing despite rigorous selection, field training often lacks sufficient supervision, and continuous education may be inadequate.
• Crisis Intervention Training (CIT) prepares officers to handle crises compassionately and effectively.
• Common crisis situations involve mentally ill individuals, domestic disputes, suicide threats, and hostage negotiations.
• Benefits of CIT: Fewer arrests of mentally ill individuals, reduced incidents of violence, and lower associated costs.

Police Stress and Mental Health

• Sources: Exposure to physical danger, traumatic events, organizational challenges (e.g., bureaucracy), and public scrutiny.
• Negative media portrayal and community relations can exacerbate stress levels.
• Effects: Increased risk of burnout, depression, anxiety, substance abuse, and high divorce rates.
• Reluctance to seek mental health support due to stigma within the law enforcement culture.
• Coping strategies: Stress reduction techniques (e.g., mindfulness, meditation).
• Peer support programs, professional counseling, and physical fitness activities can help.
• Building a supportive work environment to promote resilience.

Police-Community Relations

• Issues: Incidents of police brutality, racial bias, and excessive use of force undermine public confidence.
• Communication and transparency challenges between law enforcement and diverse communities.
• Solutions: Implementing community policing strategies to foster collaboration and mutual respect.
• The use of body cameras to increase accountability.
• Enhanced training focused on de-escalation, cultural competency, and ethical conduct.

Future of Policing (Task Force Recommendations)

• Building trust by promoting diversity within police forces to reflect community demographics.
• Emphasizing procedural justice to ensure fairness in all interactions.
• Implementing civilian oversight boards to review police practices.
• Encouraging peer reviews to foster accountability among officers.
• Establishing clear standards for the ethical use of emerging technologies.
• Using data analytics to improve crime prevention strategies.
• Mandating Crisis Intervention Training (CIT) for all officers.
• Requiring continuous education on legal updates, mental health awareness, and tactical skills.
• Focusing on physical safety, mental health support, and stress management programs.
• Promoting work-life balance and access to confidential counseling services.

Rodney King (1991)

• Beaten during an arrest in Los Angeles.
• The incident was caught on video, leading to national outrage and discussions on police brutality.
• The incident highlighted issues of abuse of power and the need for systemic reform.

Important Statistics

• Fatal Police Shootings (2014): 50% of victims were White, 26% were Black.
• Raised concerns about racial disparities in law enforcement.
• Mental Illness in Jails: 14.5% of male and 31% of female inmates have severe mental illness.
• Underscores the need for mental health interventions
