Lynch first developed the themes of "Thought Contagion" in his 1979 undergraduate senior thesis entitled "Abstract Evolution." The thesis explored the notion that an idea which can influence human behavior may blindly evolve the capacity to influence its own prevalence in the human population by motivating its human hosts to engage in behavior that spreads the idea. Just as a virus which elicits sneezes from its human host is more likely to survive by passing from host to host than a similar but non-sneeze-provoking virus, Lynch hypothesized that an idea which stimulated its host to proselytize, e.g., "Go and make disciples of all nations" (Gospel of Matthew 28:19), would be more likely to survive and become popular than an idea which did not elicit such activity. He identified other mechanisms which might also increase an idea's market share and longevity, such as influencing the human host to produce more children than it otherwise would, to instruct one's children in the belief earlier and more rigorously than one otherwise might, to isolate or effectively immunize oneself or one's children from exposure to competing ideas, to actively impede the communications of nonbelievers, or to utilize mass communications media to spread the idea to people that the host would never personally meet.
