Overall, 65.67 percent of male handwriting was correctly identified, whereas 66.08 percent of female handwriting was correctly identified. Another theory is that women's prenatal hormones generate more "feminine" handwriting, which has more curled and bowed-out letters than straight letters. Also, men tend to write with their left hand, while women usually write with their right. These differences may be why police officers often have trouble identifying criminals by looking at their handwriting. Even if two people use the same script font, their writing will still appear unique because of how their muscles move their hands and fingers. The human body is uniquely designed for life on earth. Handwriting is just one of many ways in which men and women differ from each other. The next time you read something in the newspaper that claims there is a link between gender and handwriting, remember that these studies are always based on small samples of people so they are not very reliable.
