Independently of the creativity movement, others have demonstrated the benefits of creating positive fields. The term field was derived by Kurt Lewin and states that behavior is determined by the totality of influences on an individual in a given situation. (Lewin, 1935) I have reviewed a number of cases involving field below and added some from my own creativity experiences. I then explore the psychological explanation of why such fields are effective and go on to the findings of recent brain research, which not only reinforce the benefits of positive fields but also throw light on the difficulty of creating them. Finally, I offer some suggestions from my own experience of what can be done to create positive fields. I believe that this should now be the focus of our efforts: to the extent that we are successful, we should get the creativity and innovation we need as a by-product!
