Thank you, I've now had time to read your post a second time and parse your other questions. Here are my answers.

(What is counterparty risk, by the way?)

The CDC will be an adequate source for this. I don't know and can't figure out how to find out when they'll next release an estimate of how common ASDs are. If they do it before the DSM-V comes out or shortly after it comes out, then I would wait and take not the next but the one after. If they wait until the DSM-V has been in use for a while, and I'm not sure how long a while should be, then maybe just the next one.

I am not well-calibrated enough to give good probability estimates and I worry that I'd just be making something up if I tried to give a number. I also revised down slightly from six hours ago considering what you and Yvain have said. I still think having this out there, even imperfectly, is of social utility because until recently, the better diagnosis model and the epidemic model had both predicted increasing prevalence. I wouldn't bet on it because, among other reasons, this prediction isn't really about proving me right or wrong. It's about proving a model right or wrong. If that model is wrong, then I update. I change my beliefs and actions, but then I move on. I don't "change sides" or anything like that. However, the model stands or falls here (or at some future predetermined point farther on, if one in 86 is still not the correct prevalence) and if it's going to survive, I want to see it believed by everyone, partly because proving this model eliminates the vaccine injury model (among others). You, who have reasoned that accumulated mutations are a reasonable model, are really not my opponent here.

I also admit that I want this model to be true because even without the hard work of educating people, it would show that there's no epidemic to be scared of, which might make educating people easier. That could cloud my judgment, but an empirical test will not have clouded judgment.

Fair enough?
