   I think you are on crack for this one. 15% ?! You seriously think there's a 15% chance that a embryo selection and/or genetic manipulation for IQ will be developed, commercialized, and turned into an infrastructure capable of modifying roughly 9 million pregnancies a year? Where the hell are all the technicians and doctors going to come from, for one thing? There's a long lead time for that sort of thing.

   Ditto - America doesn't have that many phlebotomists, and would go batshit over a Collegeboard requirement like that. There would have to be an enormous national outcry over nootropics, and there's zero sign of that, and tremendous takeup of drugs like modafinil. Even a urine or spit test would encounter tremendous opposition, and the Collegeboard has no incentive for such testing. (Cost, blame for false positives, and possibly dragging down scores which would earn it even more criticism. To name just the very most obvious negatives.)

   I think you forgot the part of your prediction where all the candidates went insane and agreed to such an incredibly status-lowering procedure, gave up all privacy, and completely forgot about how past candidates got away with not releasing all sorts of germane records.

   I recently read a book on old age public policy; amidst the endless details and financial minutia, I was deeply impressed how many ways there were to effectively means-test, even inadvertently, without obviously being means-testing or having that name. Judging could be very difficult.

   With a probability that high, shouldn't you be desperately diversifying your personal finances overseas? Either fork of your prediction means major pain for US debt, equity, or cash holders.

   The odds of an Iranian bomb aren't that terribly high, much less such an outcome happening.

   Definitions here are an issue. Some forecasts are for 2-500 billion dollars in defaults on student loans, which likely would provoke another bailout. Would that count? Does a 0% Fed rate and >0% Treasury rate constitute an ongoing bailout? etc.

All in all, this is a set of predictions that makes me think that I really should go on Intrade. I did manage to double my money at the IEM; at the time I assumed it was because I got lucky on picking McCain and Obama for the nominations, but if this is the best a random LWer can do, even aware of biases, basic data, and the basics of probability...
