Dropbox gave us access to project-folder-related data, which we aggregated and anonymized, for all the scientists using its platform over the period from May 2015 to May 2017 — a group that represented 1,000 universities. This included information on a user’s total number of folders, folder structure, and shared folder access, but we and Dropbox employees could view no personally identifiable information.
What we did see was every Dropbox folder associated with a given researcher, along with whom they’d shared the folder with, how often the folder was accessed by anyone associated with it, the duration of collaboration on a project, and how users split their time among different projects represented by the folders—a wide variety of specific touchpoints. We also had reliable data on seniority levels of users, such as whether they were senior or junior faculty. Overall, we analyzed data for roughly 400,000 unique users working on about 500,000 separate projects.
