It is not surprisingly Americo-centric for a post titled "How Islamic terrorists reduced terrorism in the US". I acknowledged that there was a bigger (numeric) fall in terrorism in the US in the 70s. The fall in the US after 2000, though, is probably as big or bigger when expressed as a percent drop rather than as an absolute drop. Equal efforts at reducing a variable results in drops that are similar by percentage more than by absolute number. (That means the effort to go from 100 cases per year to 10 is more similar to the effort to go from 10 to 1 than to the effort needed to go from 900 to 800.)

There has been no fall in terrorism worldwide; just the opposite. It was at its lowest point in 1971-1975, and is over 10 times as high now (as measured by GTD incidents). For Europe at a whole, it was at its lowest in 1970, then was high from 1976 to 1997. For "(USSR & the Newly Independent States (NIS))", there was no terrorism until 1989 (imagine that!), then a steady rise until 2010. The fall I pointed out for the US after 2000 also happens in a graph for Western Europe, which I would expect, but not for the world as a whole.

There is a sudden dramatic fall in Central America bottoming out in 1998, to just a few incidents per year. This might be due to a similar thing happening with the drug wars there, or might just be bad data.

Any recommendations for some books or online resources on management?

I've recently became a team leader of a small(5 people) group of software developers. I haven't had management experience before, so I want to learn something about it. But I suspect that most of literature in this sphere is bullshit, not based on good evidence. I am interested to know what information on management LW users found useful.

It seems to me that if we're going to be formalizing the idea of the relative "moral importance" of various courses of action to different moral theories, we'll end up having to use something like utility functions. It's unfortunate, then, that deontological rules (which are pretty common) can't be specified with finite utility functions because of the timelessness issue (i.e., a deontologist who doesn't lie won't lie even if doing so would prevent them from being forced to tell ten lies in the future).

Surveyed.

Minor nitpick: I think it is better to clarify definition of Europe in calibration question. Because if you go to Wikipedia to check which definition of Europe survey authors had in mind, you will immediately see Europe population on the same page.
