When dealing with those pushing pseudoscience, like the antivaccination cult, the most frustrating thing is that they tend to ignore and deny the most basic tenets of science. If denying the fact of gravity would further their goals of “proving” vaccines are neither effective nor safe, they would do so. And now that it’s flu season, they’re producing zombie tropes about flu vaccine ingredients.
If the antivaccination movement didn’t lead to epidemics of long-gone diseases, which can harm and kill children, the conversation would be over. I would just put the vaccine deniers in the same group as evolution deniers (creationists) or gravity deniers (there has to be some, somewhere). I would mock their pseudoscience, and move on. Of course, their denialism does lead to deaths of children, so we have to do what is right, and stop their lies, misinformation and ignorance in every forum we can.
We have to appeal to scientific values, and despite the fact that antivaccination pushers don’t share those values, we must continue to try. I have gotten enough emails and comments from people that they have started to vaccinate because of what I have written, so maybe some child’s life is better because all of us who support vaccines are heard.

One of the central tenets of the pro-science world is that “correlation does not imply causation” – but it is misused and frequently abused by many writers. Frequently, those trying to push a position, like anti-vaccine, will immediately assume if we can show correlation, then we can automatically leap to causation. Thus, in their world, correlation implies causation. However, real science demands both evidence of correlation and separate line evidence of causation, in which case, we can conclude that correlation implies causation. It all depends on your quality of evidence.
Conflating causation and correlation is somewhat different than the logical fallacy of post hoc ergo propter hoc, where one thinks one event follows the first event because of the existence of the first event. I’m sure all good luck charms and superstitions, like walking under a ladder, are related to the post hoc fallacy. But, if I walk under a ladder, then trip on a black cat, and then crash into a mirror, I don’t immediately blame the initial act of walking under the ladder. I just assume I’m clumsy.
Correlation and causation are a very critical part of scientific research. Basically, correlation is the statistical relationship between two random sets of data. The closer the relationship, the higher the correlation. However, without further data, correlation may not imply causation, that the one set of data has some influence over the other.

If you spend any amount of time on the internet researching science and pseudoscience, you’ll find alarming claims about toxic or poisonous substances in our foods, vaccines, air, water, and so much else. And then you’ll find a lot of people (myself included) who try to present science-based evidence that these substances are neither toxic nor poisonous.
Generally, the pseudoscience argument proceeds along the lines of “this unpronounceable chemical is going to cause cancer.” And the science (read scientific skeptic) side says “wrong!” Or something like that.
Paracelsus, a 16th century Swiss German physician, alchemist, astrologer, is traditionally thought to have founded the discipline of toxicology, an important branch of medicine, physiology, and pharmacology. Paracelsus wrote one of the most important principles of toxicology:
All things are poisons, for there is nothing without poisonous qualities. It is only the dose which makes a thing poison.
In other words, if you’re speaking about substances in foods or vaccines or anything, the most important principle is that the dose makes the poison (or toxin). Everything that we can consume or breathe is potentially toxic, but what is the most overriding principle must be the dose. Continue reading “Simple math – the dose makes the poison”
