of dehumanization—accompanied the destruction and taking of Jewish property. This constituted a dignity taking. Undocumented workers in the United States have also been subject to dehumanizing dignity takings when employers treat them as machines instead of people to justify dangerous working conditions. When harsh conditions lead to bodily injury or death, the property destroyed is the physical body. Media-driven dehumanization The propaganda model of Edward S. Herman and Noam Chomsky argues that corporate media are able to carry out large-scale, successful dehumanization campaigns when they promote the goals (profit-making) that the corporations are contractually obliged to maximize. State media are also capable of carrying out dehumanization campaigns, whether in democracies or dictatorships, which are pervasive enough that the population cannot avoid the dehumanizing memes. Non-state actors Non-state actors—terrorists in particular—have also resorted to dehumanization to further their cause. The 1960s terrorist group Weather Underground had advocated violence against any authority figure and used the "police are pigs" meme to convince members that they were not harming human beings but merely killing wild animals. Likewise, rhetoric statements such as "terrorists are just scum", is an act of dehumanization. In science, medicine, and technology Relatively recent history has seen the relationship between dehumanization and science result in unethical scientific research. The Tuskegee syphilis experiment, Unit 731, and Nazi human experimentation on Jewish people are three such examples. In the former, African Americans with syphilis were recruited to participate in a study about the course of the disease. Even when treatment and a cure were eventually developed, they were withheld from the African-American participants so that researchers could continue their study. Similarly, Nazi scientists during the Holocaust conducted horrific experiments on Jewish people and Shiro Ishii's Unit 731 also did so to Chinese, Russian, Mongolian, American, and other nationalities held captive. Both were justified in the name of research and progress, which is indicative of the far-reaching effects that the culture of dehumanization had upon this society. When this research came to light, efforts were made to protect future research participants, and currently, institutional review boards exist to safeguard individuals from being exploited by scientists. In a medical context, some dehumanizing practices have become more acceptable. While the dissection of human cadavers was seen as dehumanizing in the Dark Ages (see history of anatomy), the value of dissections as a training aid is such that they are now more widely accepted. Dehumanization has
