Books like Predictably Irrational and Sway have revolutionised the way people view human behaviour. Now Professor Clifford Nass has discoered a set of rules for effective human relationships, drawn from an unlikely source - his study of people's interactions with computers. Based on his decades of research, Nass demonstrates that people treat computers and other devices like people; empathising with them, arguing with them and forming bonds with them. Nass's discoveries provide nothing less than a new blueprint for successful human relationships.
