There is a dating guide for Stanford University (PDF file), and it includes a foreword by Philip Zimbardo.
Hookup vs. Dating Seems that the 'hook up' is gaining popularity with girls (it's always been popular with boys) in high school and college these days. More and more women are looking to expend their sexual energy in a manner that they perceive to be safe and committment-free. Why didn't this happen when I was in high school?
Where were these girls when I was in college I just graduated a year ago and I don't recall women just wanting to "hook up."
