Graphology is the study of handwriting. In Europe and America, it is an established method of personality assessment in personnel departments and psychiatry. In this text the author explains how handwriting may be assessed scientifically. She gives a systematic analysis of all the elements in handwriting - how the letters are formed, how the lines relate to each other, the pressure, speed and strength of the writing, the inconsistencies and the harmony and rhythm of the writing, its spontaneity and the signs and signal concealed in it. Renna Nezos is a founder member of the British Institute of Graphology and founder of the London Academy of Graphology.
