Here is a fascinating article about a handwriting expert from Houston that assists lawyers in jury selection. The expert is Alice Weiser, author of Judge the Jury: Experience the Power of Reading People.
An excerpt: "Weiser said that people who make little circle dots above the letter "i" are individual and unique, but in a quiet way. People who write larger than the lines and outside the borders strive to live by their own rules. A letter "g" that looks like a number "8" means one is inclined toward the literary, either as an avid reader or an author wannabe."
