Depending upon the school system and method of handwriting taught, we are all basically instructed on how to write in a cursive manner. Once this becomes a habit of the writer, the writing function becomes a subconscious psycho-motor skill incorporating individual characteristics of the writer. Handwriting identification has played important roles in many criminal cases over the years.
Forensic Handwriting Analysis — Expert Introduction to Handwriting Analysis Article In this document, forensic document examiner, Mark Songer, provides an introduction to the science of forensic handwriting analysis.
He discusses the steps that a forensic document examiner follows, including analysis, comparison, and evaluation. He also provides a brief example, comparing two handwriting samples, drawing attention to some of the key differences that a handwriting analyst may utilize in his analysis.
The Science of Handwriting Analysis The science of handwriting analysis is based on the premise that no two individuals can produce exactly the same writing and that an individual cannot exactly reproduce his own handwriting, otherwise known as variation.
The Process Handwriting analysis involves a comprehensive comparative analysis between a questioned document and known handwriting of a suspected writer.
Specific habits, characteristics, and individualities of both the questioned document and the known specimen are examined for similarities and differences.
Analysis - The first step is to analyze the known writing sample and the unknown writing sample for distinctive characteristics. The examiner looks for unique qualities such as letters and word spacing, letter and word slant, size and proportionality of letters, unusual formations of letters, flourishes, and other individual attributes.
Comparison - The next step is to differentiate elements from the known sample to those of the unknown sample. The examiner considers spelling, grammar, punctuation, and phraseology as well. Evaluation - The final step is to evaluate the similarities in the known and unknown samples.
While differences are a good indication of a non-match, no single similar characteristic, no matter how unique, can determine a match. Therefore, all likenesses must be considered. The examiner must make a judgment in each case by evaluating the totality of the documents.
Example The handwriting examples below are from two different writers. Structural differences 1 can be seen from the letter formations by each writer. In addition, baseline alignment 4 is considerably unique whereas one writer consistently writes on the baseline and the other repeatedly deviates below the baseline.
ASTM E provides guidance on the scope of work conducted by document examiners, and E specifies minimum training requirements.
