Novice Ideas: Handwriting Comparisons Conducted By An Untrained Individual, Maia Lister
Themis: Research Journal of Justice Studies and Forensic Science
Forensic analysis of questioned documents includes chemical analyses of paper and ink as well as handwriting comparisons. Several elements affect handwriting analyses, including the presence of discriminatory factors that can individualize a handwriting sample and whether the handwriting has been disguised. Five handwriting samples were gathered from six individuals comprising of one reference, three natural unknowns, and one disguised sample per person.

The novice showed a high level …
