Predictably Irrational - Dan Ariely

Predictably Irrational is a selection of short essays on the ways in which people are influenced by context and cognitive shortcuts (heuristics) to repeatedly make suboptimal choices. This field of economics, called behavioral economics, appears to be just catching up to what cognitive psychologists have been studying for decades. It was nonetheless an interesting book written in an engaging, chatty tone, and cited various studies by Ariely which provide new examples of these "predictably irrational" behaviors from an economic standpoint.
