Dark tourism researchers who examine sites of death, suffering, and despair have generated a significant amount of research over the past two decades. Different ways of conducting dark tourism research are emerging. These include studies oriented toward making sense of the supply and demand for such excursions, and research that explores how cultural meanings are negotiated at these destinations. There are also critiques of the wide-ranging application of the dark tourism concept, which has led some scholars to argue that it is analytically imprecise. New directions for future dark tourism research have also been proposed, including a call to shift away from discipline-centered analyses. Engaging with these developments, we suggest that the future direction of dark tourism research should involve grounding such studies in the concerns and insights offered in specific social science disciplines, including criminology and criminal justice studies among others, to add focus and precision to cross-disciplinary debates. To do so we draw from the emergence and development of penal tourism research, which examines how cultural representations of penality shape and are shaped by the practice of punishment in given societies. Since penal tourism research tends to focus on prison museums, we propose future directions for the study of this phenomenon rooted in criminological concerns for understanding how penal meaning making, including definitions of acts that are criminalized and what constitutes (in)justice, takes place in other sites of punishment memorialization including police and courthouse museums. Other future research directions include studying sites that memorialize corporate and state harms.
