Important task of handwriting inspection

1. A special test conducted by an appraiser to determine whether the handwriting on the document as evidence was written by a specific person. Also known as calligraphy inspection. Handwriting is a special trace left by people when writing, which can reflect the characteristics of writing habits gradually formed by writers in long-term writing practice. When expressing a certain length of text, it can also reflect the writer's written language habit (that is, the habit of making sentences with words) and the characteristics of text layout. These three habits constitute the writer's writing habits. Writing habits are specific and relatively stable. Specificity is determined by the subjective factors and objective conditions for writers to learn and practice using language and calligraphy skills. Relative stability is determined by the stereotype of writing ability formed in the brain through long-term study, practice and writing practice. Once this dynamic stereotype is formed, the writing habits are basically stable, and even if the writer tries to distort and disguise his handwriting, it is difficult to completely change it. The specificity and stability of writing habits are the scientific basis for handwriting inspection. Through handwriting inspection, we can not only determine whether the handwriting of a document is written by a specific person, but also analyze the personal situation of the writer, such as education level, age and professional characteristics, so as to provide clues for determining the direction of investigation.
