Building as a hub and wiki for researchers and practitioners trying to get a handle on the scientific evidence on what motivates giving to the most effective charities. Collaboration (esp. in academia) can be difficult; it can work because we have a shared interest in the impact and outcomes. We’ve just added a massive amount of content and organization: check out the “tools page“, for example, and please add your comments. You can suggest a new tool by filling out the form HERE.  We will credit your contribution.
