1. Watch the documentary and make a list of the hypotheses that are being investigated by these researchers. To what extent are these presented as fact? It is often claimed that stress can make us sick and that one’s position in the social hierarchy inuences the stressors that we are exposed to. Supporters of this claim often refer to research that in part relies on the use of primates. Two studies in particular are commonly cited as being relevant. Robert Sapolsky’s study of Serengeti baboons and Carol Shively’s research on macaque monkeys highlight that a primate’s social position can aect the level of stress hormones in the body and increase the likelihood of stress-related disease. In the National Geographic documentary Stress: The Portrait of a Killer, Sapolsky claims that the baboons in his study experience stress in a way that allows generalization of his ndings to humans. As a result, his ndings are often examined alongside the famous Whitehall studies that investigated stress in British civil servants. These generalizations and comparisons should, however, be treated with caution and the strength of the initial ndings veried.

The research studies listed below are featured in the National Geographic documentary. Read them and answer the questions to investigate the accepted truth of these ndings.
