Graphology is the analysis of handwriting in an attempt to determine the writer's personality traits. Its methods and conclusions are not supported by scientific evidence, and as such it is considered to be a pseudoscience.

Handwriting is the writing done with a writing instrument, such as a pen or pencil, in the hand. Handwriting includes both block and cursive styles and is separate from formal calligraphy or typeface. Because each person's handwriting is unique and different, it can be used to verify a document's writer. The deterioration of a person's handwriting is also a symptom or result of several different diseases. The inability to produce clear and coherent handwriting is also known as dysgraphia.
