“An example of how a viral transmission is different than normal information transmission can be illustrated thusly: if information were spread in a memetic fashion, it would infect a subject, and, were the information's traits conducive to the information's survival, then the subject would accept the idea. This is strongly contrasted with information theory, in which the information is accepted based on how useful it is to an individual, e.g. the idea is accepted because it helps the subject survive if they accept it. Viruses, being obligate parasites, do not always help their host (in this case, the subject) survive.”
