The underlying accusation of this article is that Neel and Chagnon performed their experiments without taking into account the health, feelings and overall well-being of the Yanomano. They were willing to put the lives of many innocent people at risk in order to test a very loosely based theory that Neel had developed. Examples of this are when they exploited many members of the tribe by offering gifts in exchange for sexual favors and injected a vaccine that was seen as the cause for a deadly measles epidemic.
