What drives scientists to publish their work before peer review?

Why do scientists want to share their results before they’ve been peer reviewed and published? Most are driven by the desire to get feedback from their peers, according to a US study of over 7000 university researchers across nine fields in the US, Germany and Switzerland. The research also found that almost 70% of scientists had disclosed results before publication and that physical scientists were almost twice as likely to prepublish, as not. In common with biological, agricultural and medical school scientists, physical scientists prepublished once they were sure of their results.
