Today I and my collaborators have a new paper published in PNAS! Justin Tackney, the lead author of the paper, was kind enough to write up a summary of the findings to publish here on Violent Metaphors. Here is his take:
One of the biggest issues I’ve seen again and again in the comments sections of every vaccination article is a fundamental lack of understanding of how the immune system works. Many people talk vaguely of “toxins”, “pathogens” and “immunity”, but it’s clear that they have no idea exactly how this works. So I thought that I’d invite a regular commenter, Dr. Scott Nelson, to write an explanation. I think that Dr. Nelson, who teaches this subject in university courses, has done an excellent job of making a complex topic accessible to people who are not scientists or physicians. (Note that we have provided hyperlinked definitions of many of these terms from Wikipedia for convenience. Dr. Nelson and I have both reviewed them and agree that they’re accurate. If you would like additional information beyond what is provided here, we recommend consulting any basic major textbook).
If you are “doing your own research” on vaccines, I urge you to read all the way through the end, and then watch the video, which shows an animation of the processes that Dr. Nelson describes. Finally, because I think it’s important to illustrate the vast differences between the scientific explanation of how the immune system works, and the “alternative medical” explanation, I’ve included the homeopathic version at the end of the post. I encourage you to share your thoughts on which you find most compelling, and why. My comments following Dr. Nelson’s are in bold
A common thread through many anti-vaccine posts is fear about “all the stuff that you are jabbing into a kid”. I would like all the people who think this to perform a simple experiment. Take a piece of meat-any meat-make sure it’s fresh and smells good. Put it on the counter in a nice warm place-about body temperature-cover with a screen if you like. Let it be for three days and then look at it carefully, note all the different shapes and colors. If you know somebody with a microscope, scrape a bit of stuff off and look at it under a microscope. How many different things do you see now? Each spot, each color, each bug you see under a microscope represents something that the immune system is dealing with every second of everyday. After all-wasn’t it exposed to the exact same air that you’re breathing right now? Your body is that piece of meat-your immune system is what keeps it from rotting. Right now, our best estimates are that there are 10 microorganisms for every cell in your body. Your immune system “knows” them all and has responded in various ways, which science is currently exploring. Continue reading

I’m absolutely delighted that he agreed to share his insights into pseudoscience in the martial arts with us. You can read details of his background on his school’s website here. –Jenny

Recently on Facebook I saw a video of a Finnish martial artist named Jukka Lampila who called what he did Empty Force or EFO, and claimed that with it he could control an attacker without touching him. His Facebook page proclaims him the founder of EFO. The video begins with clips of Lampila fending off ‘attacks’ from his students. He waves his arms; sometimes he twitches, and in each case the ‘attacker’ seems to be magically thrown to the mat without ever being touched by Lampila. He also shows an example of ‘controlling’ someone on the ground. He kneels calmly beside a supine student with the back of his hand gently resting on the man’s chest. “I don’t need to use any energy” he asserts as the student appears to try with all his might to regain his feet to no avail. It is a sad display of martial arts charlatanism.

A while back a friend asked me to help with a difficult conversation. Someone she cared about was expecting her first child, and had decided not to vaccinate her baby. My friend desperately wanted to change the mother’s mind to protect that child. But she wasn’t sure how to proceed. She had the facts on vaccines, and knew that refusing immunizations was a dangerous and irresponsible decision. But she wasn’t sure how to convince her friend of that without jeopardizing their relationship. There are some excellent resources for health care providers having this conversation with patients. But there wasn’t much that applied to her particular situation. So she asked me whether my experience as a negotiator gave me any insights that might help her plan for what was sure to be a difficult conversation.
As it happens, I had been thinking about the same thing. I’m particularly interested in how laypeople should approach a conversation like this, since laypeople can be much more persuasive than the family physician. In the real world, our family and trusted friends very often carry more weight than experts. The giant but useless homeopathy industry would collapse otherwise. So when you hear that one of your friends or relatives doesn’t plan to vaccinate, you have the opportunity for a conversation that could potentially change their mind and save that child from terrible harm.
Unfortunately, too many people approach that conversation timidly, without a solid strategy for persuading their friend. That makes it hard to respond when things take an unexpected twist, such as your friend spouting off antivaxer talking points you hadn’t considered. Other people are too aggressive, treating the conversation like the comments section of a blog post. That kind of combative and confrontational dialog can feel good, but it doesn’t accomplish much in the real world.
So what does a strategy for an effective, persuasive conversation look like? There is a world of advice we could give about that conversation. We’ve distilled it into four basic points: be sincere, ask questions, be sympathetic, and provide information.
After the fold, we’ll go into some specific thoughts about each one. We want to stress, though, that this is just a framework. The conversation itself will be different every time. We want to know more about your conversations. If you’ve tried to talk someone into getting a child (or themself) immunized, please share your story in the comments section.
