"It's only a decision in the sense that each day I "decide" not to go to medical school" Well, it is a decision in that sense. That's a real sense in which a decision can be made. At each point in time we choose to do one thing from among the infinite possibilities available to us. And in making the decision to do that one thing, we are making the decision not to do any of the other things, even if not consciously. I don't know where you're coming from with the "inaction is always our default position" thing. What do you mean when do you say "default"? Do you mean that we should (oof, I hate to bring "should" into this) sometimes maintain the status quo even if doing so doesn't have the highest expected outcome for us? Do you mean that we should sometimes maintain the default even if the expected outcome of doing so is dramatically lower than doing something? (I'm gonna go ahead and assume that this isn't what you believe, but if it is, our argument has to end here, because the only response that I've got is, "Well, that's really stupid.") Because I would argue that that's the situation that we're in with global warming. I actually agree with you that the scientific establishment should be treated with substantial skepticism. But I also think that global warming is probably happening, and through applications of logic I've decided that reacting to a fictional global warming is SO SO much better than not reacting to a real global warming that we'd be insane to choose inaction as long as there's still some non-infinitesimal probability that global warming's happening. You seem to think that you have an ace in the hole with your argument that our society supports an "innocent until proven guilty" approach. In fact, I am both a believer in the "expected value" approach to choosing a course of action and an ardent defender of innocent-until-proven-guilty. This is because the downside of convicting an innocent person is dramatically larger than the downside of letting a guilty man free -- not only because locking up an innocent guy for 40 years is much worse than letting some embezzler get away with it, but because every time our legal system sends an innocent person to jail the public loses some faith in it, and faith in the legal system is one of the most fundamental elements of a stable and happy society. Okay, I think I'm done. I'm pretty damn sleep deprived at the moment, though, so if I missed anything please point it out and I'll address it later. *Not a criticism.

I do see your point that in some sense we make infinite many implicit decisions all the time, but I think the word really refers specifically to the intentional act of creating a position. Though that's a semantic argument and not really important because my main point in the above comments was that this is not a now or never issue. Inaction today isn't a commitment of any kind, because the same options will be available tomorrow. Do you mean that we should (oof, I hate to bring "should" into this) sometimes maintain the status quo even if doing so doesn't have the highest expected outcome for us? No, certainly not. I mean that we should maintain the status quo until we can reasonably estimate those expected outcomes and their costs/benefits (ask questions first, shoot later). This article is arguing that we don't yet have those reasonable estimates. I think the "innocent until proven guilty" approach is and expected value approach. Public loss of faith in the system is a huge cost (probably much bigger than letting the average criminal go free). So I think there's an implicit cost/benefit analysis there. There are also costs associated with (at least some of) the proposed global warming solutions. I'm thinking specifically of cap and trade, a system with far reaching economic consequences we can't fully understand until it's actually implemented. So before we implement it, we'd better know with some degree of certainty that the current situation is bad enough to warrant a potentially dangerous economic experiment. On the other hand, I think investment in alternative energy is a relatively low cost decision (sort of a "what the hell, it can't hurt").
