Rock, Paper, Scissors: Game Theory in Everyday Life
Basic Books (2008)
Whether we want to understand where a shared supply of teaspoons has disappeared to, or why countries take themselves to the brink of nuclear war, Game Theory reveals the decision-making process. In Rock, Paper, Scissors, Len Fisher explains Game Theory, the study of co-operation and the underlying strategies that shape human behaviour.
Game Theory is all around us in everyday life, shown by Len’s amazing examples, including:
- navigating the etiquette at a dinner party
- calculating the proper distribution of gifts at a child’s birthday party
- playing ‘chicken’ with commuters on New York City sidewalks
- bargaining in Indian street markets
Len Fisher’s writing brings this science of interaction to life with anecdotes and applications that are sure to spark the imagination and give you pause for thought. Dealing with collaboration, co-operation, competition and confrontation, Rock, Paper, Scissors is essential reading for anyone interested in what it takes to get people to work together.
