For years, social media platforms promised transparency and collaboration with the research community. But after the 2018 Facebook–Cambridge Analytica scandal, that partnership largely evaporated (Tromble, 2021). Today, researchers trying to understand how social media affects our emotional well-being face unprecedented obstacles, with profound implications for public health.
The Data Access CrisisThe shift is dramatic. Platforms that once offered open access through application programming interfaces (APIs) now operate as what researchers call the "post-API age" (Freelon et al., 2024). When APIs were available, researchers could systematically collect data on user behavior, emotional reactions to content, and patterns of engagement. Now, those doors have largely closed.
While billions of people communicate on social media daily, independent researchers have systematically lost the ability to study what's happening on these platforms. Meanwhile, the algorithms and platform companies that shape what users see and feel maintain strict control, granting meaningful data access only to internal teams or a narrow circle of affiliated scholars (Kishwar, 2025).
