There are two types of
hand writing analysis
groups
Graphology study of how handwriting
reflects a persons personality and
character traits
Questioned Document Examiner or
Forensic Document Examiner
=determining whether a questioned
writing of unknown origin was authored
by a person whose known writings are
available
Graphology
► Has
been called a pseudo science There are many
individuals who, in evaluating the legitimacy of
graphology, place it on the same level as
astrology.
► There are, indeed, a great number of individuals
who fervently believe in the worth of graphology
as a reliable method to learn valuable information
about the personality of an individual through his
or her writing.
Graphology
► Not
a modern invention
► Roman Emperor Nero is said to have judged
the abilities of his associates by a study of
their handwriting
► Italian scholar Camillo Baldi is said to have
authored the first treatise on graphology in
1625, under the loosely translated title of
"How to know the nature and qualities of a
person by looking at a letter he has
written."
Graphology
► Abbe
Michon, a French monk, wrote about
the relationship between handwriting and
personality in a book wherein he referred to
the study as "graphologie."
Graphology
► International
Graphoanalysis Society (IGAS).
► learn the principles of graphology, and
become "graphoanalysts" through home
study.
► 18-month course
► (1) identifying strokes; (2) relating these
strokes to specific personality traits; and (3)
evaluating the relative strength of the
interrelated traits

In death threats
In suicide notes

Comparisons Are Useful Because
► No
two people have identical handwriting
► By adulthood, it is exclusive to an individual
(we all learned the same techniques to
begin writing in grade school)
► Even disguised handwriting will exhibit
some of the person’s individual
characteristics
Standard Comparisons
► Include
sample to be analyzed called an
EXEMPLAR
► Samples from an individual include
 Collected writing comes from prior to the
beginning of the investigation (helps prevent or
indicate when a person is disguising their
handwriting)
 Requested writing is a dictated text using the
same type of paper
 Same type of ink as the sample to be analyzed
Forensic Document Examiner
► The
best thing to examine is something with the
same words as the document in question.
► An examiner may dictate to a potential suspect,
slowly then faster so that they have less chance of
disguising the handwriting.
► Use same ink and paper (as said before) pencil,
ballpoint pen, fountain pen, marker, etc.
Forensic Document Examiner
► List
ways a person may change or attempt
to disguise their handwriting
Forensic Document Examiner
► Name
items that you could get from a
potential suspects home to use for
handwriting identification.
Forensic Document Examiner
► Handwriting
originates in the brain when a
mental picture of letters and words is
formed. The signal to try to duplicate the
mental picture is sent to the arm and hand
through the muscles and nervous system.
The actual output is almost never an exact
match of the original mental picture.
Forensic Document Examiner
Handwriting is distal, meaning that it occurs
at the extremities and involves fine motor
activity as opposed to a skill like walking
which is proximal - a large, or gross motor
skill. One reason individuals find it difficult
to simulate the handwriting of others is that
to do so successfully requires understanding
the essence of the writer's motor control
program and executing that same program.
Forensic Document Examiner
►
Some typical document examination questions
►
Is the signature genuine?
►
Is the document forged, and if so is it forged by a particular person?
►
Is the same person the author of several documents?
►
Did someone guide a person's hand as a will was signed?
►
Did the doctor come back later and alter the medical records?
►
Did the signer of the document also initial the changes?
►
What is written under the crossed out portion of the writing?
►
Was the document written on the date indicated?

FAQs
Can you describe an individual's
personality from examining
handwriting?
No, forensic document examination does not develop information
about personality. There is a separate field of study called
"Graphology" which deals with personality and handwriting.

FAQ
Can right or left handedness be
detected by examining
handwriting?
Contrary to popular belief, there are three things that can not be reliably
ascertained by examining handwriting. One of those is the "handedness" of
the writer. The other two things are the author's gender and age.

FAQs
Can you compare printed writing
to cursive writing?
Rarely. Some writers style of writing is a mix of cursive and printed forms,
thereby allowing the examiner to carry out some level of examination on
either cursive or printed writing. There are also many factors other than letter
formation that enter into the examination and and analysis process. However,
it is generally accepted that the materials to be compared need to be written
in the same style: cursive to cursive, hand printing to hand printing, upper
case to upper case, lower case to lower case,

FAQs
Can you examine documents in a
foreign language?
Yes, it is possible, but the examiner must first learn about the
characteristics of the written language and how that writing is taught

FAQs
Can a document examiner work
with photocopies of questioned
documents?
This question must be answered on a case by case basis. If the copy
is of good quality, and if there is enough information in the writing to
allow an opinion, a copy can be sufficient. But there are some
situations where the opinion rests on a subtle aspect of the writing
that might only be visible on an original viewed under the microscope.

FAQs
Can a client fax documents to you
for examination?
There is a wide range in reproduction quality of faxed documents.
Until recently a faxed document was of minimal use for comparison of
handwriting. The fax process could digitize the writing line, obscure
details, and add flaws to the document. A large number of fax
machines still produce poor quality documents. However, there are
now higher quality fax machines, and there is also a process of
electronic faxing in which a document is scanned and transmitted to a
virtual fax number through the internet
Shredded Material Recovery
► The
purpose of our work was to turn bags
of shredded documents like these...
Shredded Material Recovery
► Into
legible documents like these...
Shredded Material Recovery
► Which
involved separation of individual
shreds from the pile and re-assembling
them piece by piece.
Shredded Material Recovery
► Each
bag of shredded paper contained an
average of 100 recoverable documents.
Shredded Material Recovery
► As
a result of the hard work and persistence
of our dedicated team, 426 documents were
