Could two similar signatures be copies of the same image? What does a scan leave out? Start with a question, explore an example and see how far the evidence takes you.
Handwriting and graphology (15)
Baseline direction
The baseline is an imaginary guide supporting the bodies of letters.
Handwriting and graphologyChoosing comparison samples
A useful sample has a known writer and contains material comparable with the questioned passage.
Handwriting and graphologyConnections and pen lifts
A visible gap and an actual pen lift are not necessarily the same event.
Handwriting and graphologyDisguised handwriting
Disguise means that the writer deliberately altered their writing. Distinguishing it from natural change requires care.
Handwriting and graphologyGraphology and personality claims
Graphology associates handwriting with personality. Each proposed link needs an independent test of its predictive value.
Handwriting and graphologyGraphology in employee selection
The historical use of handwriting in hiring raises a testable question.
Handwriting and graphologyLetter size and proportions
Absolute height and the proportions within a letter are separate observations.
Handwriting and graphologyLetter slant
Slant describes the angle of strokes relative to the writing line.
Handwriting and graphologyLine quality
Examiners consider how a stroke travels, breaks and changes along its path. With a photograph the first question is which details the image actually retains.
Handwriting and graphologyNatural variation in handwriting
A person may form one letter several ways even within one sentence. Comparison needs a range of examples rather than the nearest match.
Handwriting and graphologyObservation and interpretation
Good notes let another reader locate the detail, understand what was examined and see the limits of the inference.
Handwriting and graphologyShort signatures and initials
An abbreviated signature can contain few movements to compare. The first question is how much information it carries.
Handwriting and graphologyWhich hand held the pen?
Signature slant alone cannot identify the writing hand.
Handwriting and graphologyWord and letter spacing
Gaps between words and gaps inside a word are different measurements.
Handwriting and graphologyWriting systems and languages
Writing systems differ in how signs are formed and joined. Start by identifying the script actually used in each document.
