It seems reasonable that our handwriting unconsciously reveals things about our personal characteristics. The revelations will be subtle, to be sure, but with enough research, studies, and testing, it should be possible, the reasoning goes, to establish rules to allow for the accurate analysis of personality from handwriting. And, indeed, the claim that such rules are available and can be practically applied, at least by experienced initiates, is the fundamental principle underlying the discipline of graphology, or handwriting analysis. I read whatever material on the topic I could find.

In some cases, it might be the one piece of evidence that gets a suspect charged and eventually convicted.
But what if it's a false match? How exactly do experts go about analyzing someone's handwriting?
In the world of forensic analysis, which includes crime scene investigationDNA testingfiber 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.
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.
The primary basis of handwriting analysis as a science is that every person in the world has a unique way of writing. When we were all kids in primary school, we learned to write based on a particular copybook - a style of writing.
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. So at first, we all probably wrote in a similar way to kids of our own age and location. But with the passing of time, those writing characteristics we learned in school - our style characteristics - became only the underlying method of our handwriting.
We developed individual characteristics that are unique to us and distinguish our handwriting from someone else's. Most of us don't write the way we did in first or second grade.
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.
First and foremost, handwriting analysts must be able to accurately distinguish between style characteristics and individual characteristics, which takes a lot of training.
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. The individual characteristics are what matter the most in determining authorship.
It's the differences that initially determine if it's possible that the same person wrote both pieces of text. Simulation has its own telltale characteristics, which we'll discuss in the next section. However, if the differences don't rule out a match, and there are significant similarities in the individual traits in the two documents, singular authorship becomes a possibility.
Moving from possibility to probability is where the heavy lifting comes in.This science fair project is based on the DragonflyTV episode "Forensics by Kalia and Carolyn." In the video, Kalia and Carolyn apply forensics to a birthday party crime scene.
They collect evidence, come up with a list of possible perpetrators, and apply different methods to . Transcript of Graphology Science Project Almost everybody's handwriting was similar, no matter how they answered the personality questions.
For example, a lot of people with small handwriting, said they were outgoing, instead of the expected answer which was shy. Science Fair Project Topics To Avoid Especially For High School Students!
The data from this type of science fair project tends to be unreliable and therefore should be avoided. (handwriting analysis) This type of project is highly subjective and difficult to measure. Transcript of Graphology Science Project Almost everybody's handwriting was similar, no matter how they answered the personality questions.
For example, a lot of people with small handwriting, said they were outgoing, instead of the expected answer which was shy. Without measurement, you cannot do science. Graphology or handwriting analysis.

The analysis may discuss mistakes made while conducting the experiment or ways in which the project could be improved in the future.
