It never ceases to amaze me how much humanity clings to the feeling that they understand something, even when history tells us that surprises are far more common than predictability. It seems to me that planning for Ebola (or a battle, or climate change, or the economy, or anything vaguely important) wouldn't be something along the lines of "Ok, we know what's going on, no need to freak out or to spend any extra effort" but "Wow, these things go sideways <i>all the time,</i> let's assume our models are limited, in ways we don't even know yet, and throw everything we have at it; even then we will probably be lucky if we dodge a disaster."<p>I really don't have any more confidence because the CDC has been saying "it will be fine" than I did when the Japanese officials said Fukushima would be fine.<p>Enough optimism for the morning...
