Given the differences in variation and selection mechanisms, it is also possible to make predictions about the competition between memes and genes. Hence, censorship is analogous to attempts to halt diseases by spraying insecticides. Censorship can never fully kill off an offensive meme, and may actually help to promote the meme's most virulent strain, while killing off milder forms. In memetics, ideas are viewed as almost independent creatures in a symbiotic relationship with human minds and cultures. A vector is anything that transports the meme between hosts without the capacity to reflect on the meme.

Then she is just a non-reflective carrier of the meme, much the same as a book. Elaboration Something that a host actively thinks about is less likely to be forgotten, and also more likely to influence behavior. Thus memes that encourage thinking or fantasizing about themselves or related concepts have increased chances of survival. Rituals and ceremony are often powerful reminders of the meme. If a meme is to be spread by a host for a long time , the host must remember the meme.
