Handskriftsjämförelser

Handskriftsjämförelser, also known as handwriting comparison or graphology, is the examination and comparison of handwriting specimens to determine authorship or to identify individuals. This field is often employed in forensic science, where questioned documents may be compared to known handwriting samples from a suspect. The process involves analyzing various characteristics of the handwriting, including letter formation, slant, spacing, pressure, and size. Experts look for unique features and consistency across samples.

The reliability of handskriftsjämförelser has been a subject of debate. While some studies suggest a high degree of accuracy when performed by experienced forensic document examiners, others have raised concerns about subjectivity and the potential for error. The scientific validity of graphology, a related but distinct field that claims to interpret personality traits from handwriting, is widely disputed and generally not accepted within the scientific community. In legal contexts, expert testimony on handwriting comparison must often meet specific standards of admissibility.

In addition to forensic applications, handskriftsjämförelser can be used in historical research to attribute anonymous documents or to trace the development of writing styles over time. The principles applied involve meticulous observation and a systematic approach to identifying both similarities and differences between examined scripts. The outcome of a handskriftsjämförelse is typically a conclusion about the probability of two or more samples originating from the same writer.
