The book ‘Predictably Irrational: The Hidden Forces That Shape Our Decisions’ by Dan Ariely presents rationality in a completely different perspective to what many people give it. In this well-written book, Ariely takes the reader through a journey of understanding how expectations, emotions, social norms among other frailties that are out of ones’ sight shape our decisions. Full of real-life case-study examples coupled with the latest empirical research, the book explains what we actually do and how we can indeed learn more about our wonderful ways of making the silliest of errors.
