Forensic Psychology: All You Need to Know as a Beginner!


When the words “forensic” or “forensics team” are mentioned, the first thing that comes to mind immediately for most of us is crime investigation.

Many of us have heard the terms used often in well-known movies and shows like “Mystery Street”, “Law and Order”, “Forensic”, “The Bone Collector”, and “Criminal Minds”, and our association of the terms with crime investigation has become almost like a reflex.

But, what really is forensic? And more importantly, what is forensic psychology?

Well, this beginner’s guide to forensic psychology covers everything about the field including what it means, its origin, how it works, its benefits, its application, and the commonly asked questions about it.

What Forensic Psychology Really is

When it comes to defining forensic psychology, there is a long and short way to do it.

Beginning with the shortest and the simplest definition, forensic psychology is said to be the process of applying clinical psychology knowledge and understanding to the legal world (1).

The longer definition states that forensic psychology is the process of putting various clinical skills like evaluation, assessment, and treatment into practice to help make forensic work and legal processes successful.

The word “forensic” itself means using scientific and psychological knowledge to solve legal issues.

Forensic psychology combines law and psychology, and many of the concepts in different fields of psychology such as cognitive psychology and social psychology come into play here.

In essence, it looks at how human behavior is connected to the justice system.

Clinical skills including interviewing, assessing, case representing, strong communication skills, evaluating, consulting, and reporting are critical when working with forensic psychology.

You will find most forensic psychologists playing a part in evaluating school threats, recruiting police offers, assessing a witness’ ability to provide information on a case, helping crime victims through their recovery process, determining the effect of post-traumatic stress disorder, and providing the necessary care for both young and old lawbreakers (which is also known as forensic therapy) and assessing child protection and custody cases.

In the grand scheme of things, forensic psychology allows forensic psychologists to understand and improve human behavior and overall well-being in regard to the law. It also aims to reduce the negative effect and behaviors portrayed by lawbreakers.

History of Forensic Psychology

Although forensic psychology seemingly appears to be a relatively new branch of psychology, research into the area and its practical application in various aspects of the law began decades ago.

Here is a timeline of memorable moments and figures in forensic psychology that contributed to making it what it currently is:

The oldest recorded instance of use of forensic psychology was noted from Wilhelm Wundt back in the 1890s.

Wundt established his laboratory in Leipzig, Germany where he did research and experiments that led to discoveries and insight which would be extensively applied in forensic psychology by psychologists who came after him (2).

James McKeen Cattell probed into the reliability of witness testimony by experimenting with university students. His findings on how less credible witness information is, led other psychologists to dig more in the area to determine how helpful witnesses can be in the courtroom.

Alfred Binet moved the baton forward in forensic psychology by analyzing the previous research on law and psychology and made several developments. His focus and attention on intelligence testing helped psychologists who came after him to create assessment tools that gave the field of psychology a boost forward.

William Stern asked students to describe an altercation between two students that had happened in their class. He noted that emotions affected memory. Later on, he went on to set up an academic journal focused on applied psychology.

Hugo Munsterberg, who many believe to be the “father of forensic psychology”, experimented with psychology and the law extensively. Afterward, he published a book called “On the Witness Stand” that promoted the application of psychological concepts to matters regarding the law.

Albert von Schrenck Notzing was asked to provide his expert input on how suggestibility affects the testimony’s credibility of a witness in a court case that involved murder charges.

Lewis Terman improved upon the intelligence test by Alfred Binet and later changed its name to the Stanford-Binet intelligence test. The test helped to determine how intelligent the law enforcement applicants were during interviews.

William Marston’s discovery of the connection between blood pressure and truth led to the development of the polygraph detector.

A key development note in the field of forensic psychology was when more courts began turning to forensic psychologists for advice and information about various aspects of human behavior and their relation to the law.

Some of the cases where forensic psychologists played a useful role include the cases of Jenkins versus the United States in 1954, People versus Hawthorne in 1940, and Frye versus the United States in 1923.

In 2001, the APA (American Psychological Association) qualified forensic psychology as a specialty in psychology, and since then, it has grown and diversified tremendously (3).

How Forensic Psychology Works

Forensic psychology touches different diverse fields and aspects, but from a legal standpoint. Most of the work performed here comes from a need that is backed by legal requirements for the achievement of a specific goal.

It can help a child’s parent get justice and support from the other parent, help the court understand if a suspect in a criminal case deserves a pardon or a harsh sentence, and in the recruitment of police officers.

Moreover, this branch of psychology can allow us to understand the common behaviors associated with criminal acts, and how can reduce them at the moment and prevent more of them from happening in the future.

It also aims to help certain processes within the justice system run smoothly so that people can get the justice they deserve and bring more peace to the world.

To put things more categorically, forensic psychology improves the world in two ways, academically and practically.

When it comes to academics, some forensic psychologists specialize in research and help us understand the psychology of things in terms of the law and the justice system. They run experiments on suspects, convicted criminals, and try to understand their mental and behavioral aspects so that they can determine why they do what they do.

The knowledge and insight gained from the research help to provide solutions to challenges like ways to reduce criminal activities, profiling a criminal, understanding the motives behind certain criminal behaviors, and testifying as a witness as well as an advisor to the court.

When it comes to the application or the practical approach to forensics, many forensic psychologists apply the knowledge and principles of forensic psychology to help systems run more effectively. For instance, they can help determine the mental health status of a criminal during the period a certain crime was committed.

They can also work with kids to prepare them for a child custody and support case. They can also assess a suspect’s mental health condition and provide treatment. Plus, they can help screen potential police officers and help get the best candidates for the job.

Forensic Psychology subspecialties

Forensic psychology is further subdivided into different subspecialties, which include:

1. Correctional subspecialty – This subspecialty deals with some areas such as rehabilitating convicted criminals, assessing them for release requests, and training prison workers.

2. Criminal subspecialty – Among the many responsibilities of this subspecialty is to do risk assessment, which involves determining how much of a threat a lawbreaker is to the public. Also, it helps figure out if a suspect is fit enough health-wise to be tried and convicted in a courtroom.

3. Police subspecialty – This field is all about police officers. It seeks to help police departments create a reliable screening process for law enforcement applicants, and train them to handle various citizens with health issues. It also helps police officers come up with a profile for a difficult case with unknown suspects or criminals, and counsel officers after a gruesome incident at work.

4. Juvenile subspecialty – Here, forensic psychologists help juvenile courts decide if a juvenile offender is mentally and intellectually capable to stand trial. Moreover, they assess and recommend better treatment and rehabilitation techniques for convicted youngsters.

5. Investigative subspecialty – The forensic psychologists who specialize in this area help the police in investigations. They work with witnesses in preparing them to provide useful and credible information for cases in court. They also perform autopsies in murder cases and help with polygraph tests.

6. Civil subspecialty – Here, the knowledge of forensic psychology is applied to civil cases including divorce, insurance, child custody, and family feuds. Psychologists in such cases help to determine claims, injuries, physical and psychological damages incurred and provide reports that can help with settlements.

Benefits of Forensic Psychology

Looking at how forensic psychology brings the greater good to humanity, here are some benefits we enjoy from this branch of psychology:

– Helping us understand human behavior in relation to crime

– Helping us predict a criminal’s behavior

– Helping us have strong, effective, and reliable systems to administer justice

– Helping us solve civil cases properly with the correct evidence

– Helping a child’s information in a case be more trustworthy

– Helping governments recruit only the best law enforcement officers

– Helping us find proper treatment and rehabilitation solutions for young and older lawbreakers

– Helping authorities which convicted criminals to release who have genuinely changed their ways and who don’t pose a threat to the general public

– Helping law enforcers get a good image of a suspect based on a witness’ description and in turn solve crimes better

Requirements to be a Forensic Psychologist

Although every country has its own requirements for people who are interested in becoming forensic psychologists, some of them appear to be similar.

Many countries require that you have a Doctorate of Psychology degree, commonly referred to as PsyD, or a Ph.D. in psychology from a well-recognized university or psychology institution. Others also ask for a master’s degree in forensic psychology to launch your career in the area, although you may be limited if you don’t advance your education.

A bachelor’s degree in criminology and criminal justice can also help you steer towards the direction of forensic psychology.

For the most part, the path you take in your education is hugely dependent on the type of job in forensic psychology you want to get.

The education you ideally get leans towards Law, Social behavior, Criminal psychology, Criminal justice, Abnormal behavior, Pharmacology, Clinical psychology, Cognitive psychology, and Perception. So, taking a course on any of the areas and determining what you want to be in the field of forensic psychology will help you define your path easily.
