It’s the intellectual bromance of the last century. Two psychologists — Danny, a Holocaust kid and adviser to the Israel Defence Forces, and Amos, a former child prodigy and paratrooper — meet at the end of the 1960s, and sparks immediately begin to fly. They spend countless hours locked in rooms together at Hebrew University and elsewhere, and eventually co-write a series of papers that will revolutionise the field, and lead to the surviving partner being awarded the Nobel prize in economics.
