Each pixel on Facebook.com is highly tested to maximize sign ups. It is interesting to see the word “Sex” used so subtly, even though you didn’t notice your subconscious did.
The word “Sex” is extremely powerful, it gets people excited. One big reason a lot of students sign up for Facebook is to see what their crush (slang for romantic interest) is doing. So seeing the word “Sex” has to help peak their interest to sign up for Facebook.
Google Plus and most sign up forms I’ve seen around the web use “Gender” instead of “Sex” (see screen shots below).
Do you think Facebook is using Sex to their advantage? I’d love to know in the comments.
