Project NOW is a scientific study about factors that influence the decisions gay and bisexual men make when meeting new sexual partners online. In this study, guys come to our offices and complete questionnaires and other tasks on the computer that are designed to simulate online interactions. Our hope is that the data from this study will help us learn more about how things like beliefs, attitudes, and other internal influences interact with contextual factors to influence what these men think, feel, say, and do in these situations.
