We can always use more case studies of insanity that aren't religion, right?
Well, Miracle Mineral Supplement is my new go-to example for Bad Things happening to people with low epistemic standards. "MMS" is a supposed cure for everything ranging from the common cold to HIV to cancer. I just saw it recommended in another Facebook thread to someone who was worried about malaria symptoms.
It's industrial-strength bleach. Literally just bleach. Usually drunk, sometimes injected, and yes, it often kills you. It is every bit as bad as it sounds if not worse.
This is beyond Poe's Law. Medieval blood draining via leeches was far more of an excusable error than this, they had far less evidence it was a bad idea. I think if I was trying to guess what was the dumbest alternative medicine on the planet, I still would not have guessed this low. My brain is still not pessimistic enough about human stupidity.
I don't think point and sputter posts like this are very useful. How is this example more surprising than any other quack medicine example? How much understanding does the typical patient have of any medicine? Lots of medicines are controlled doses of poisons.
I think you are mistaken about the lethality. It would be surprising if it "often" killed its users, yet was able to spread. But that's not true. Yes, it is sold at industrial concentrations, but most people follow the directions and dilute it. The FSA says that, used as directed, it will only cause GI distress (though the FDA suggests that the low blood pressure could be fatal). Users are warned of the effects ahead of time. That probably reassures them that it is working, that they haven't been scammed with an inactive substance.
What is the death rate? The Seattle case appears to involve 200 users and no fatalities. The woman who died in Vanuatu appears to be the only known death, but I don't think much is known about the hundred thousand malaria victims in East Africa who took it.
I don't think this demonstrates human stupidity any more than any other quack medicine example. It does nicely illustrate Poe's law. That may make it more memorable and convincing.
Added: By "point and sputter" I mean that Eliezer did not provide enough information for me to determine what surprised him about this example and why it would be a useful example to give to others. I think he reached much of his conclusions from false beliefs about how the product is described and how lethal it is, but I don't know. Certainly, what the impression I took away from his post was false.
Whether you change beliefs in response to a new case will depend on the nature of the selection or sampling process . If you go through a history of quack medicine, you'd get lots of new case-studies but you might not change your beliefs about typical human epistemic performance at all.
Even if new cases are selected to be examples of human stupidity, they might still be roughly random within that class. So cases that are more extreme than one's expectation will shift your beliefs. But this might leave your beliefs about the frequency of incidence of human... (read more)
