A processor-implemented method, system, and/or computer program product mitigate subjectively disturbing content. A context-based data gravity wells membrane supports one or more gravity wells, which hold subjectively disturbing synthetic context-based objects made up of a non-contextual data object, a first context object, and a second context object. The first context object defines the non-contextual data object, and the second context object describes how subjectively disturbing content generated by combining the non-contextual data object and the first context object is according to predefined parameters described by the second context object. New content is passed across the context-based data gravity wells membrane. Subjectively disturbing content from the new content is trapped by the context-based data gravity well in response to a non-contextual data object and context objects from the new content matching those of the context-based data gravity well, thereby reducing a level of subjective discomfort imposed by the new content.
