How Do Forensic Psychologists Determine Insanity & Competency?

Thanks to courtroom dramas, terms like “not guilty by reason of insanity” and “not competent to stand trial” have become part of the public lexicon. But what do these legal phrases truly signify, and how do they play out in actual courtroom scenarios?

Forensic psychologists are key players in evaluating both competency and insanity, two critical factors that determine a defendant’s ability to participate in legal proceedings. Their assessments are integral to helping attorneys and judges interpret these legal concepts and make informed decisions.

Competency pertains to whether a defendant can understand the charges and proceedings against them, while insanity focuses on their mental state at the time the alleged offense occurred.

Understanding Competency, Sanity, and Insanity in Legal Proceedings

Understanding Competency in Legal Proceedings 

Competency is a crucial factor in determining if a defendant can actively participate in their trial and comprehend the legal process. In essence, competency ensures the defendant:

• Possesses the capacity to collaborate with their attorney in a rational and meaningful way.
• Maintains both a logical and factual understanding of the trial and its proceedings.

This standard, as defined by the Supreme Court, underscores the importance of mental acuity and awareness in upholding fair and just legal practices.

Understanding Sanity and Insanity in the Legal Context

Sanity plays a critical role in determining whether a defendant can be held accountable for their criminal actions. While the definition of insanity differs across states—and some states do not recognize an insanity defense at all—it fundamentally addresses the defendant’s mental state during the commission of the crime.

The insanity defense is rooted in the notion that individuals who lack a sound mind at the time of their offense are incapable of fully grasping the nature or wrongness of their actions. As such, they may not be held criminally responsible.

It is important to note that a defendant deemed competent to stand trial can still be found not guilty by reason of insanity. On the other hand, if a defendant is found incompetent to stand trial, the legal process halts, and no verdict—guilty or not guilty—can be reached.

Legal Perspectives on Insanity

Insanity is evaluated through various frameworks, often tailored to the nuances of specific cases:

1. Legal Definition
   This perspective focuses on whether a mental disorder or defect rendered the defendant incapable of understanding or appreciating the criminal nature of their actions.
2. Moral Definition
   Here, the emphasis is on societal ethical standards. A defendant may be considered insane if their mental condition prevents them from recognizing their conduct as a violation of moral norms.
3. Subjective Definition
   This approach examines the defendant’s personal moral reasoning. Even if they understood their actions were illegal or socially unacceptable, their mental disorder might have led them to believe their behavior was morally justified.

Each of these interpretations highlights the complex interplay between mental health and the law, reflecting the multifaceted ways insanity can be defined and applied in legal proceedings.

Key Distinctions Between Competency and Insanity in Legal Proceedings

Who Decides: Judges vs. Juries

In the legal system, the determination of competency and insanity follows distinct processes. A judge is responsible for assessing competency before the trial begins, while a jury evaluates insanity at the trial’s conclusion as part of the verdict.

How Competency and Insanity Are Addressed

Competency can be raised by an attorney or identified by a judge based on observations. If there are reasonable grounds to question a defendant’s competency, the court typically orders an evaluation by a forensic psychologist. The results of this evaluation guide the judge’s decision on whether the defendant is fit to stand trial. In contrast, insanity requires the defendant to plead it as a defense during the trial.

The Role of Law: Federal vs. State

Competency is rooted in the due process clause of the U.S. Constitution, turning it into a federal law issue. Insanity, on the other hand, is governed by state law, with varying criteria and availability of the defense. Notably, some states do not recognize an insanity defense at all.

By understanding these distinctions, legal professionals and defendants can better navigate the complexities of the justice system.

The Impact of Competency and Insanity on Legal Proceedings

Competency and insanity play crucial roles in shaping legal proceedings, especially when a defendant’s mental state is in question. Judges assess a defendant’s competency based on their ability to comprehend the trial and participate in their defense. This determination relies heavily on a forensic psychologist’s professional evaluation. If the psychologist’s findings indicate the defendant is not competent to stand trial, the court pauses the criminal process. The individual is then provided with appropriate treatment until they regain the capacity to proceed.

Insanity, conversely, centers on evaluating the defendant’s mental condition at the time the offense was committed. Unlike competency, it is the jury’s responsibility to weigh the evidence, often guided by expert testimony from a forensic psychologist. If the jury concludes that the defendant was legally insane—categorized as Guilty but Mentally Ill (GBMI) or Not Guilty by Reason of Insanity (NGRI)—the defendant is generally committed to a psychiatric facility for treatment and rehabilitation.

The procedures for psychiatric commitment differ across states. In some jurisdictions, a formal hearing is required to authorize the commitment. Other states streamline the process, allowing automatic placement in a facility following the verdict.

Guidelines for Assessing Legal Insanity 

Understanding legal insanity presents a unique challenge, as it is defined within a legal framework rather than a psychiatric one. This distinction means that even a diagnosed mental disorder does not inherently establish insanity. Forensic psychologists play a critical role in evaluating whether a defendant’s mental condition impaired their ability to comprehend the nature or wrongfulness of their actions at the time of the offense.

In the U.S., the plea of “not guilty by reason of insanity” is exceptionally rare, making up only about one percent of all criminal cases. Among these, only 25 percent of insanity defenses successfully prove legal insanity, highlighting the rigorous standards required.

Forensic psychologists rely on specific clinical tests to determine whether a defendant could discern right from wrong during the crime. Common tools used in these evaluations include:

• Slobogin Mental Screening Evaluation
• Rogers Criminal Responsibility Assessment Scales

This evaluation process is intricate, requiring psychologists to analyze data from multiple sources, perform diagnostic interviews, and administer psychological tests. Based on this comprehensive assessment, they present their findings and expert opinions to the court.

How Forensic Psychologists Evaluate Competency to Stand Trial: Best Practices

The American Academy of Psychiatry and the Law estimates that approximately 50,000 to 60,000 competency evaluations are conducted annually in the United States. Evaluating whether a defendant meets the legal standards for competency to stand trial has become a cornerstone skill in forensic psychology, crucial to ensuring fair legal proceedings.

Tools Used by Forensic Psychologists for Competency Evaluations

Forensic psychologists rely on a variety of tools to assess competency, ranging from preliminary screening tests to detailed evaluation frameworks. Among the most commonly used methods are:

• Competency to Stand Trial Screening Test (CST): This standardized, 22-item test, developed by the National Institute of Mental Health, provides an initial assessment of a defendant’s competency.
• Competency to Stand Trial Assessment Instrument (CAI): A semi-structured interview tool that evaluates 13 key areas of competence-related functioning, offering a more in-depth analysis.
• Georgia Court Competency Test (GCCT): Widely utilized for assessing a defendant’s factual understanding of court procedures and their specific case details.
• Evaluation of Competency to Stand Trial-Revised (ECST-R): A newer instrument designed to evaluate a defendant’s factual and rational understanding of legal processes and their capacity to effectively work with legal counsel.

Formulating a Competency Opinion: Key Considerations

Using these tools, along with clinical interviews and case-specific evaluations, forensic psychologists must provide a well-founded forensic opinion. This opinion hinges on addressing three critical questions:

1. Symptomology and Diagnosis: What symptoms does the defendant exhibit, and what is the corresponding psychiatric diagnosis?
2. Connection to Competency Standards: How do the symptoms and diagnosis relate to the jurisdiction’s legal requirements for competency?
3. Potential for Restoration: If the defendant is deemed incompetent, what is the likelihood of restoring competency through treatment, and what type of setting would be most effective?

The Role of Mental Disorders in Competency Findings

Most defendants found incompetent to stand trial are diagnosed with a mental disorder, as outlined by the American Psychiatric Association. This underscores the importance of forensic psychologists in identifying these conditions and determining their impact on the defendant’s ability to engage in legal proceedings.

By following these established guidelines and leveraging specialized assessment tools, forensic psychologists play a pivotal role in upholding the integrity and fairness of the legal process.

Common Misconceptions About Competency and Insanity

The legal concepts of competency and insanity are often misunderstood, leading to significant misconceptions. This confusion is largely driven by portrayals in popular media, a lack of clear public education, and the complexity of legal definitions. 

Media Portrayal vs. Reality

Movies, television dramas, and sensationalized news stories often depict legal terms like competency and insanity in ways that blur the lines between fact and fiction. For example, fictional court cases might show defendants “getting off easy” by pleading insanity, perpetuating the myth that this legal defense is a convenient loophole. In reality, such defenses are rare, complex, and require substantial evidence, including expert psychiatric evaluations.

Moreover, media tends to conflate competency—whether someone can understand legal proceedings and participate in their defense—with insanity, which pertains to a person’s mental state at the time of committing a crime. This confusion not only misleads audiences but also shapes public opinion, often fueling stigma against individuals with mental health issues.

Misunderstood Legal Terms and Their Impact on Public Perception

Competency refers to a person’s ability to comprehend and participate in legal proceedings, ensuring they receive a fair trial. Insanity, on the other hand, is a defense strategy asserting that a defendant was unable to distinguish right from wrong due to a severe mental illness at the time of the crime. These terms serve distinct purposes in the justice system but are frequently mistaken for one another.

This misunderstanding has real-world consequences. Public misconceptions can influence jury biases, policy discussions, and even the willingness of defendants to seek appropriate legal representation. Additionally, these misconceptions can perpetuate stereotypes about mental illness, making it harder for those affected to receive compassion and proper care.

Examples of High-Profile Cases and Their Outcomes

Several high-profile cases demonstrate the complexities and challenges surrounding competency and insanity in the courtroom. For instance, the trial of John Hinckley Jr., who attempted to assassinate President Ronald Reagan, brought national attention to the insanity defense. Hinckley’s acquittal by reason of insanity sparked widespread debate and led to reforms in how such cases are handled.

Similarly, the competency hearings for defendants like Ted Kaczynski (the Unabomber) illustrated the intricate evaluations required to determine whether someone can stand trial. These cases show that competency and insanity are not mere technicalities but pivotal aspects of ensuring justice is served while respecting individual rights.

Conclusion
