They can pretty much ignore the style characteristics, which are only useful for determining with a fair degree of certainty which copybook the writer learned from. And while two or more people may share a couple of individual characteristics, the chance of those people sharing 20 or 30 individual characteristics is so unlikely that many handwriting analysts would say it's impossible.įirst and foremost, handwriting analysts must be able to accurately distinguish between style characteristics and individual characteristics, which takes a lot of training. Most of us don't write the way we did in first or second grade. We developed individual characteristics that are unique to us and distinguish our handwriting from someone else's. But with the passing of time, those writing characteristics we learned in school - our style characteristics - became only the underlying method of our handwriting. So at first, we all probably wrote in a similar way to kids of our own age and location. Which copybook our handwriting is based on depends on when and where we grew up (see Handwriting-L: Copybook Examples for good examples of copybooks from different countries and eras). When we were all kids in primary school, we learned to write based on a particular copybook - a style of writing. The primary basis of handwriting analysis as a science is that every person in the world has a unique way of writing. Handwriting analysis is a tedious and methodical process that relies on extensive knowledge of the way people form letters, which characteristics of letter formation are unique and the physiological processes behind writing - the ways in which a person's fine-motor skills can affect his or her handwriting and leave clues about the author's identity. Questioned document examiners (QDEs) analyze documents for signs of alteration, forgery and, when sample documents are available, handwriting or typing comparisons to determine or rule out authorship (and/or tie a document to a specific machine in the case of typing). In the world of forensic analysis, which includes crime scene investigation, DNA testing, fiber analysis, fingerprint analysis, voice identification and narcotics analysis, to name just a few of the disciplines, handwriting analysis fits into the area of questioned documents. But what if it's a false match? How exactly do experts go about analyzing someone's handwriting? In some cases, it might be the one piece of evidence that gets a suspect charged and eventually convicted. When there's a suspect in a crime and the evidence includes a handwritten note, investigators may call in handwriting experts to see if there's a match. 1956 Weinberger kidnapping: An FBI-conducted analysis made a match between the top two sign-offs ('Your baby sitter'), pulled from the ransom notes, and the bottom two, from the prime suspect.
