Why anti-vaxxers are liberal and conservative

Michael Gerson writes in WaPo:

[A] significant minority of parents — often well-educated parents — are opting out of vaccination. Many states (including California) make it relatively easy to refuse vaccination for “philosophic” reasons. This does not, I suspect, mean that people are reading Immanuel Kant or John Stuart Mill; it means they are consuming dodgy sources on the ­Internet.

Resistance to vaccination on the left often reflects an obsession with purity. Vaccines are placed in the same mental category as genetically modified organisms (GMOs), DDT and gluten. But the problem with organic health care is that the “natural” rate of child mortality is unacceptably high. Organically raised children can get some very nasty ­diseases.

Opposition to vaccination on the right often reflects an obsession with liberty — in this case, freedom from intrusive state mandates. It has always struck me as odd that a parent would defend his or her children with a gun but leave them vulnerable to a microbe. Some conservatives get especially exercised when vaccination has anything to do with sex — as with the human papillomavirus (HPV) vaccine — on the questionable theory that teenagers are more likely to fornicate if they have a medical permission slip (or less likely to without it).

Whether hipsters or home-schoolers, parents who don’t vaccinate are free riders. Their children benefit from herd immunity without assuming the very small risk of adverse reaction to vaccination. It is a game that works — until too many play it.

Herd immunity requires about 90 percent vaccine coverage. Some children with highly vulnerable immune systems — say, those being treated for leukemia — can’t be vaccinated for medical reasons. When the number of non-medical exemptions from vaccination gets large enough, the child with leukemia becomes the most vulnerable to the spread of disease.

The government (in this case, state governments) has the responsibility to keep vaccination rates above 90 percent, which benefits everyone. This requires burdening the freedom of parents in a variety of ways — not putting them in jail if they refuse to vaccinate but instead denying them some public good (such as public education) and subjecting them to stigma (which they generally deserve). As the rate of vaccination goes lower, the level of coercion must increase — making exemptions more difficult and burdensome to secure (as California needs to do).

Observations in the aftermath of Sandy

1. The traffic in the blackout areas of Manhattan is lawless in the most literal sense: the traffic lights aren't working, so the law cannot be applied as usual. But "lawless" doesn't seem to be a fitting description; the driving seems better-behaved than usual. We're so used to seeing people act under a system of government rules that it's easy to assume that without the rules, everything would descend into chaos. But perhaps free people are generally capable of acting decently on their own. Of course, that's never going to be universal; but then, people break the law too. In fact, a dense set of rules tempts people to see how close to (or how far across) the borderline of legality they can go without being penalized. In the absence of governmental laws, people might focus more on other kinds of laws: social norms and ethics.

[Added: There actually is a law that applies when the traffic lights aren't working, but people probably don't know about that law, and they definitely aren't following it. We never get the chance to do a pure experiment on how people would act in the absence of any government, but this is closer to such an experiment than we usually get.]

2. Whenever there's a high-profile disaster, whether it's a storm or a mass murder or terrorism, so many people's instinct is to declare that their political ideology has been vindicated.

3. I like Adele, but the people who work at Starbucks must get tired of listening to nothing but Adele.
