Economic Incentive

Today’s XKCD is making the rounds — it’s not only hilarious, but an incredibly devastating way to look skeptically at the world.

A lot of things obviously cannot be debunked using economic incentive, but looking at who is making the money from something and how they are doing so is an interesting way to see through problems.

For example, when you look at homeopathy, who actually is profiting from it? Companies that don’t have to bear the onerous financial burden of proving anything to the FDA. This is potentially going to cost them in the UK, where their nationalized health service is no longer going to cover homeopathic medicine, but the companies are still allowed to sell what is essentially water as honest to goodness medical cures right alongside real, actual medicine.

Would they make more money if homeopathy actually worked? Of course they would, governments and insurance companies would make a killing. They’d just go to their local tap water and add a molecule of arsenic, and bam, millions of lives saved.

Then, there are individuals who make money from various made-up powers: psychics, tarot readers, and religions. How do they make their money? From gullible believers who give it to them. Would a psychic make more money if they were genuinely psychic than if they were tricking gullible people? Yes, they’d constantly be winning lotteries or finding buried treasure or controlling people’s minds to get into their Last Will and Testament. “I, the Queen of England, leave all of my money and property to David Blaine.”

Would religions make more money if they were selling a God that was real and as advertised? If prayer actually worked, everyone would be religious. If God really did smile on the faithful, the faithful would be rich as hell. And if he really smote the non-believers, Norway would have burned to the ground by now and secular Europe would have found God. How much money would the Vatican make if they could sell limb regrowing and cancer cures?

Can you imagine a world where there was no dissembling and these things could just point us to an actual track record of recorded miracles? Miracles that actually mattered, too, not just Grilled Cheesus or Bleeding Statues.

Economic incentive is complicated, of course. One of the anti-vaccine arguments is that Big Pharma is selling vaccines to make a big profit and that doctors push them on patients to get bonuses. But, there’s an even bigger profit motive from the government and insurance companies to keep people from getting sick. Blue Cross is more likely to get insurance payments from someone who lives past the age of 5, Kaiser is going to pay a lot less for a kid who doesn’t get paralyzed by Polio, and the government is going to get a lot more productive work hours out of kids who haven’t been permanently damaged or killed by preventable diseases.

And then there’s Andrew Wakefield, who started the anti-vax movement. He had a profit motive — he wanted to sell his own vaccine instead of the one that was popular at the moment. If that doesn’t discredit a movement, I don’t know what could.

So economics is a powerful tool in debunking, but you definitely need the whole picture — it’s easy to twist one incentive into the only incentive. Of course, most of the people who believe aren’t going to be dissuaded by the economic argument, but it’s certainly one that people innately understand. Money, as they say, talks.

Anti-Vaxers

Someone on my blogroll posted something anti-vaccine, citing the rise in autism cases as just one reason that we should “stop poisoning our bodies”.  As someone who wouldn’t be alive if not for the radical medical intervention of the 20th century, I’m incredibly skeptical of anyone who claims that we’re poisoning our bodies with drugs without also acknowledging that we also don’t typically die in childhood and the life expectancy is over 40.

There is no link between vaccines and autism and more importantly, vaccines save lives. The increase in autism is partially to do with different diagnostic conditions, the introduction of autism as a spectrum disorder — to focus on the phony and disproven and discredited link invented by a doctor trying to sell his vaccine as better than the current one is to fail to research the real causes of autism.

Again there are 0 ties between vaccines and autism. It’s just a lie. The fact remains that when children are not vaccinated they get diseases that can kill them and make it more likely that the vaccinated kids will get those diseases as well. I’d rather have an autistic child than a dead child. And I’d rather not die because people are making up reasons to not trust the good science that’s been done.

Should you believe everything that comes from big pharma? No, of course not. And should you want to treat autism and be skeptical of anything that people put in their bodies? Sure. But you should also be able to rationally look at the human costs of not vaccinating children and the motivation behind the lie that there was a connection between vaccines and autism in the first place. Post hoc ergo propter hoc.
