Evolutionary psychologist Geoffrey Miller examines modern consumer culture through a scientific lens. The result is thought-provoking, useful and often witty, but a bit uneven. Miller does of fine job of explaining evolutionary psychology and, especially, of showing how the endless purchases that define “consumerist capitalism” come from an unacknowledged need to demonstrate physical characteristics or personality traits to others. This section of the book will interest anyone seeking original social critique. The highly focused discussion of the “Central Six” personality traits provides a stable foundation for evaluating other people or marketing to them.

  • What “Central Six” traits people share – and what those characteristics mean.
