PZ Myers seems to have pissed off quite a few people, this time for taking Steven Pinker to task. His take is worth reading in full, but I’d like to add another angle. In the original interview, there’s a very telling passage:
Belluz: But as you mentioned, there’s been an uptick in war deaths driven by the staggeringly violent ongoing conflict in Syria. Does that not affect your thesis?
Pinker: No, it doesn’t affect the thesis because the rate of death in war is about 1.4 per 100,000 per year. That’s higher than it was at the low point in 2010. But it’s still a fraction of what it was in earlier years.
