been associated with modern medicine generally and has explicitly been suggested as a coping mechanism for doctors who work with patients at the end of life. Researchers have identified six potential causes of dehumanization in medicine: deindividuating practices, impaired patient agency, dissimilarity (causes which do not facilitate the delivery of medical treatment), mechanization, empathy reduction, and moral disengagement (which could be argued to facilitate the delivery of medical treatment). In some US states, legislation requires that a woman view ultrasound images of her fetus before having an abortion. Critics of the law argue that merely seeing an image of the fetus humanizes it and biases women against abortion. Similarly, a recent study showed that subtle humanization of medical patients appears to improve care for these patients. Radiologists evaluating X-rays reported more details to patients and expressed more empathy when a photo of the patient's face accompanied the X-rays. It appears that the inclusion of the photos counteracts the dehumanization of the medical process. Dehumanization has applications outside traditional social contexts. Anthropomorphism (i.e., perceiving mental and physical capacities that reflect humans in nonhuman entities) is the inverse of dehumanization.. Waytz, Epley, and Cacioppo suggest that the inverse of the factors that facilitate dehumanization (e.g., high status, power, and social connection) should promote anthropomorphism. That is, a low status, socially disconnected person without power should be more likely to attribute human qualities to pets or inanimate objects than a high-status, high-power, socially connected person. Researchers have found that engaging in violent video game play diminishes perceptions of both one's own humanity and the humanity of the players who are targets of the game violence. While the players are dehumanized, the video game characters are often anthropomorphized. Dehumanization has occurred historically under the pretense of "progress in the name of science". During the St. Louis World's fair in 1904, human zoos exhibited several natives from independent tribes worldwide, most notably a young Congolese man, Ota Benga. Benga's imprisonment was put on display as a public service showcasing "a degraded and degenerate race". During this period, religion was still the driving force behind many political and scientific activities. Because of this, eugenics was widely supported among the most notable US scientific communities, political figures, and industrial elites. After relocating to New York in 1906, public outcry led to the permanent ban and closure of human zoos in the United States. In art Francisco Goya,
