Abstract
Using the wave/particle duality, a central principle in quantum physics as a metaphor, this article describes two different modes of human interaction that a negotiator should be aware of when conducting her negotiations-within, i.e. her internal negotiations with regard to how a situation should be approached, before and during the actual negotiation. The first section presents the wave/particle duality. The second section makes the transition from physics to discuss the centrality of the wave/particle duality in human everyday experience and suggests that a wave-like negotiation mindset and approach can be taught. The third section shows basic differences between wave-like and particle-like interactions, also suggesting that the ongoing debate in the literature between interest-based and relational approaches can be read in the light of the wave/particle tension or duality. The fourth section offers an analysis of the characteristics of wave-like interactions that should be cultivated by negotiators and discusses the considerations one should take into account when negotiating-within and deciding on the type of negotiation that should be applied.
