Antifragile by Nassim Nicholas Taleb has implications that I find impact very disparate areas. It's hard work in places though. The Quark and the Jaguar by Murray Gell-Mann is a wonderfully readable and accessible intro to complexity, which again is a topic that seems to crop up all over the place. Delusions of Gender by Cordelia Fine cites a shedload of research to dispel gender-related myths. It should be taught in schools, in my opinion.
