The ISIS Prisons Museum aims to expose and document ISIS crimes in Iraq and Syria in order to achieve justice. Its in-depth investigations are an important source of evidence concerning those crimes. The investigations examine and analyze forensic evidence, witness testimonies, and the documents left behind by ISIS. They seek to understand the ISIS governance system, and its judicial organization and prisons network. Other major topics of research include mass graves, and specific massacres or incidents of ethnic cleansing. ISIS oppressed individuals, particular segments of society, and ethnic and sectarian groups in specific ways. 

The IPM carefully examines and records what was done to these various groups. It also looks into the motivations, context, and types of resistance mounted by local communities that lived for years under ISIS tyranny. The IPM methodology is based on thorough analysis and cross-referencing of the available data, with expert opinion sought to corroborate findings.

The IPM adheres to the strictest standards in publication ethics, protecting the privacy of its sources. It avoids publishing views, content, or descriptions that might gratuitously offend.
