Can a memorial really stop a genocide? Only if it does more than just remember.
A three-year study of over 400 memory sites around the world found that simply building a memorial does not automatically prevent future atrocities [2]. The research concluded that memory sites become preventive only when they actively work to reduce specific risk factors for mass violence, such as dehumanization of out-groups, political exclusion, and weak rule of law [2]. This means a museum or monument must host educational programs, community dialogues, or early-warning systems that address current tensions, not just display artifacts from the past.
For example, a site that teaches about past atrocities can help break cycles of dehumanization by humanizing former victims, which directly counters a key psychological driver of genocide [4]. But a site that simply glorifies one group's suffering while ignoring others' can actually increase the risk of future violence by deepening social divisions.
The dark side of memory: how remembering the past can fuel new violence.
Historical memory is a double-edged sword. The same research that shows memory's preventive potential also warns that selective or politicized memory can be used to justify new atrocities [1][4]. For instance, the debate over the 1915 relocation of Armenians in the Ottoman Empire has become heavily politicized, with some narratives framing it as self-defense rather than genocide, which can be used to legitimize similar actions today [1]. This shows that memory is not inherently good or bad—it depends on who controls the narrative and for what purpose.
A psychological model of mass atrocities, based on case studies from Indonesia, Cambodia, East Timor, and Myanmar, highlights that denial and justification of past crimes are key steps that enable new violence [4]. When a society refuses to acknowledge past atrocities honestly, it creates a permission structure for future perpetrators to believe they will not be held accountable. This is why the quality of memory—accurate, inclusive, and critical—matters more than the mere fact of remembering.
AI and digital tools can twist historical memory in dangerous new ways.
The rise of generative AI poses a new threat to the preventive power of historical memory. AI can now create convincing but false narratives and images about past atrocities, potentially spreading denialism and distortion faster than ever before [3]. Because AI models are trained on limited data—often missing the full context of complex historical events—they can produce biased or inaccurate accounts of genocides and war crimes [3]. This could undermine the credibility of memory sites and make it harder for societies to learn accurate lessons from the past.
On the other hand, digital technologies also offer opportunities for more inclusive and creative memorialization, allowing marginalized voices to be heard [3]. The challenge is to harness these tools ethically, ensuring that AI-generated content about atrocities is clearly labeled and grounded in verified facts, so that memory serves prevention rather than manipulation.

A psychological model based on four Southeast Asian case studies shows that denial and justification of past atrocities are key processes that enable future violence, making honest memory critical for prevention.
Cultural Heritage and Mass Atrocities
The destruction of cultural heritage is inseparable from mass atrocities, as both aim to eliminate a people and the identity markers they cherish, meaning memory of cultural loss is part of atrocity prevention.
