New paper published today in Proceedings B: Why war is a man's game [Open Access!]. I'm grateful for the useful feedback I received from various people throughout the process and especially at EHBEA & HBES. Also thanks to The Conversation UK for the opportunity to write an article explaining my results to a wide audience: check it out. Also very glad about the media attention this paper got: Phys.org, Daily Mail, Yahoo News, UPI, and more...
