It stands to reason that some people, for whatever reason, are somewhat less susceptible. It would be a strange world indeed if the susceptibility was exactly the same across all humans. Many questions quickly surface, though. How can we tell who is less susceptible? How can we mode this variance? A single fixed number from 1 to 100 is certainly insufficient. And even if we can start to understand these phenomena, under what conditions can we actually apply the new knowledge for widespread benefit? What are the risks?
