Way more likely than you think. Recently attended a writers' conference at which one of the speakers gave a speech on the subject; I think there was also a TV piece on one of those newsmagazine shows (20 Minutes or 60 Hours or 48/48 or one of the others). A skilled reader can frequently identify the author of a written piece from word use, spelling errors, punctuation tendencies, etc. And with a high degree of accuracy. ----- jim o\-S
