Inspired by an article and a test in The New York Times Magazine, the Gender Genie uses a simplified version of an algorithm developed by Moshe Koppel, Bar-Ilan University in Israel, and Shlomo Argamon, Illinois Institute of Technology, to predict the gender of an author.

After pasting in a long blog post made a while back the genie determined I was male:
Female Score: 869
Male Score: 1071

I tried it on another long post with the same result. I’m not that surprised.
