I thought I recently read about a book arguing that trends in warfare, when you use the right statistics on the right timescales, do not show a clear decline over time. The book was characterized as effectively a rebuttal to Steven Pinker's The Better Angels of our Nature. Now I cannot remember where I read about it and Google is not helping me find it. Is there such a book?
The recollection I have is that the source was talking about a book, published in the past year or two, written by an author I wasn't familiar with, which rules out a paper by Taleb and Cirillo. If no positive answers are forthcoming, though, then that paper combined with my inaccurate recollection is the way to bet.
For what it's worth, I am a fan of Pinker's book, but I think a serious contrary response that goes beyond critiquing Pinker's analysis would be interesting.
