The role of fear in violence globally is complex and important. As our understanding of global violence advances, so has awareness of the deleterious efforts of exposure to fear on human development and on exacerbating collective violence. The Forum on Global Violence Prevention of the National Academies of Sciences, Engineering, and Medicine will convene a two day workshop focused on: the biological impacts of fear and trauma on the body system, racism and xenophobia, how perception/misperception, culture, and the media influence far in relationship to violence, and more.
