The title is quite misleading – this is by no means a self help book! It will not tell you how to become happy. In fact, I’d say that Daniel Gilbert truly appreciates the uncertainty and ambiguity that is happiness, its subjective uniqueness in each human’s mind, and therefore, even when he gives us his perspective on how one can predict the chances of one’s happiness, he underplays it!
I found the book to be a systematic deconstruction of happiness which takes it into realms such as cognitive science, psychology, behavioural economics and even philosophy to a certain extent. Right from the explanation of the literal ‘blind spot’ in our optical mechanism, the ‘deal’ between the eye and the mind, and then using this blind spot as a metaphor for the lacunae in our perception and imagination, it is a fascinating step-by-step analysis of how we perceive happiness, with studies and examples to back it all up. He is also able to point out why our own predictions of happiness regularly go wrong, even on events which are repeats of our own earlier experience!
