Analysis of Historical Contagion Experiments
Greg Carlwood reviews the data from 203 historical contagion experiments cited in Daniel Roydas's book. He notes that in studies where healthy people were exposed to sick donors through coughing, sneezing, and shared items, only 12% became ill. Furthermore, 10% of control groups developed symptoms after receiving an inert placebo, suggesting that the nocebo effect and psychological expectation play a significant role in respiratory illness.
