The Importance of Handwriting Analysis in Criminal Investigations
6 min read

Handwriting analysis may be an often overlooked tool in criminal investigations, but it is powerful. By comparing two or more handwriting samples, investigators can make educated assumptions about the person who wrote them and determine if they match up with other evidence at the scene. 

This article will discuss the importance of handwriting analysis in criminal investigations and how it has become more valuable in recent years as technology has advanced. We will also cover some of the best practices for analyzing handwriting samples and how experts use this evidence to build a stronger case for law enforcement.

What is Handwriting Analysis?

Handwriting analysis studies an individual's handwriting to identify specific personality traits or characteristics. It is often used in criminal investigations to narrow down the list of suspects and help develop a profile of the perpetrator.

Several factors can be analyzed in handwriting, such as pressure, slant, size, spacing, and strokes. Each of these factors can reveal something about the writer's personality. For example, someone with a lot of pressure in their handwriting may be tense or anxious. Someone with large handwriting may be outgoing or extroverted.

Handwriting analysis is not an exact science but can be valuable in criminal investigations. It is important to remember that not everyone will exhibit all the personality traits associated with their handwriting, but it can still help identify possible suspects.

How is Handwriting Analysis Used in Criminal Investigations?

There are many ways that handwriting analysis can be used in criminal investigations. 

  • One way is to compare a known sample of the suspect's handwriting to handwriting at the crime scene. This can be done by comparing specific characteristics, such as letter formation, slant, and pressure. 
  • Another way handwriting analysis can be used is to analyze a note left by the perpetrator. This can provide information about the writer's mind, intent, and motivation.
  • There are many ways in which handwriting analysis can be used in criminal investigations. One way is to compare a suspect's handwriting with that of known samples of their handwriting. This can be done by looking at the overall shapes of the letters, the spacing between letters, and the pressure exerted while writing. 
  • Another way handwriting analysis can be used is to analyze a ransom note or other threatening letter. By looking at the writing style, investigators can often narrow down the pool of suspects. 
  • For example, if the note is written in all capital letters, it may indicate that the writer needs to be educated or experienced. This could help lead investigators to someone who is not accustomed to writing in complete sentences or may have a limited vocabulary.
  • Lastly, handwriting analysis can also be used to identify forgeries. This is done by looking at characteristics such as line quality, stroke order, and pressure exerted while writing. If there are significant differences between the suspected forgery and known samples of the person's handwriting, it can be used as evidence that the document is not genuine.

The History of Handwriting Analysis

Handwriting analysis, also known as graphology, is the study of handwriting in human psychology. The history of handwriting analysis dates back to the early 19th century when it was first used to diagnose mental illness. 

However, it wasn't until the early 20th century that handwriting analysis began to be used in criminal investigations.

In the early days of handwriting analysis, experts often relied on their own opinion when determining whether or not someone was guilty of a crime. This led to many false positives and resulted in innocent people being convicted of crimes they didn't commit. 

To this day, some experts still believe that personal opinion should be considered when analyzing handwriting.

However, most experts now agree that personal opinion should not be a factor in handwriting analysis. Instead, they believe that objective criteria should be used to determine whether or not someone is guilty of a crime. 

Several objective criteria can be used when analyzing handwriting, such as letter slant, letter formation, and pressure marks.

Handwriting analysis has come a long way since its beginnings in the early 19th century. Today, it is an invaluable tool frequently used in criminal investigations. However, it is essential to remember that, like all forms of evidence, it should be used alongside other forms of evidence to conclude.

How to Become a Handwriting Analyst

To become a handwriting analyst or a document examiner, you must have strong attention to detail and excellent observational skills. You will also need to be able to think critically and have experience in criminal investigations.

There are several ways to gain the necessary skills and experience to become a handwriting analyst. 

  • One way is to complete a degree in forensic science or a related field. This will give you the theoretical knowledge and practical skills required for the job. 
  • Alternatively, you can gain experience through work in criminal investigations. This could include working as a police officer, detective, or crime scene investigator.

Handwriting analysis is an invaluable tool for criminal investigations that can provide valuable insights into the identity of a perpetrator. Its ability to verify documents or uncover forgery and its use as evidence in court has made it an essential part of any criminal investigation. 

It's important to remember, however, that handwriting analysis is not foolproof and should only be relied on partially as evidence in court. Handwriting experts must always ensure their findings are accurate and unbiased.
