This research applies the concept of hormesis—where low doses are beneficial but high doses harmful—to pornography use. Since excessive porn use is associated with mental-health problems, the project seeks to identify the “healthy limit” of use. Participants will complete daily smartphone surveys over a month, allowing the researcher to model how porn consumption affects well-being and how moral beliefs modify these effects. The goal is to build a personalised app that guides individuals toward safe levels of use and reduces polarisation in debates about pornography.
