Designer VS Cultural Memes

At this point I want to introduce a distinction between mind viruses that arose spontaneously and ones that were invented by human consciousness. I'll call the naturally arising ones cultural viruses and the human-crafted ones designer viruses. A designer virus is carefully crafted to infect people with a set of memes that influence them to spread the virus throughout the population.

Designer viruses and cultural viruses can be equally damaging to your pursuit of happiness, although for many people it doesn't feel as bad to have your life ruined by a natural set of circumstances as it does to have some manipulative no-goodnik get the best of you. But despite the difference in perception, the effect of these two kinds of mind viruses is the same: you unwittingly have a portion of yourself diverted from what you might otherwise be doing with your life, and instead devoted to doing the work of the mind virus.

Some memes are designed to infect our minds, others come from our environment.
