Epidemiology is the study of populations. The impact, for example, of an environmental condition that’s toxic on an entire population. So what epidemiologists try to do is they look at the population that was exposed to the toxin and they examine outcomes, and then they look at an unexposed population with certain controls. But epidemiology is notoriously susceptible to manipulation. You could design an epidemiology study that proved that sex does not make you pregnant. How would you do that? You eliminate all the pregnant people before you did the study so that you just ended up studying people who were having a lot of sex but nobody was getting pregnant. Ergo, sex doesn’t make you pregnant. And that’s what they did with these epidemiology studies that the CDC orchestrated. They eliminated the populations that had autism before they did the study.
