A few weeks back, I reviewed a book – The Social Brain – by Tracey Camilleri, Samantha Rockey and Robin Dunbar. It takes Dunbar’s academic research and theory about the evolutionary psychology of how human groups work and, focussed on the co-authors’ knowledge of large organisations, applies it to the working world. I love that book, but I’m the kind of guy who really appreciates a VERY high-level distillation of principles to work by. So, I thought I’d return to the book and see how well I could achieve this.
