The Gender Genie uses an algorithm to predict with 80 percent accuracy the gender of the writer.
Crudely put, men talk more about objects, and women more about relationships.
Female writers use more pronouns (I, you, she, their, myself), say the program’s developers, Moshe Koppel of Bar-Ilan University in Ramat Gan, Israel, and colleagues. Males prefer words that identify or determine nouns (a, the, that) and words that quantify them (one, two, more).

The Gender Genie works best on texts of more than 500 words, so plan to cut and paste something you’ve written.
