A description of communication at the opposite end of the spectrum is presented in Adam Kahane and Peter Senge’s excellent book Solving Tough Problems [IkS04], which describes a methodology that has been used to reconcile deeply conflicting views in some very tricky real- world situations (e.g. helping to peacefully end apartheid in South Africa). One of the core ideas of the methodology is to have people with very different views explore different possible future scenarios together, in great detail — in cognitive psychology terms, a collective generation of hypothetical episodic knowledge. This has multiple benefits, including e emotional bonds and mutual understanding are built in the process of collaboratively ex- ploring the scenarios e the focus on concrete situations helps to break through some of the counterproductive abstract ideas that people (on both sides of any dichotomy) may have formed ® emergence of conceptual blends that might never have arisen only from people with a single point of view The result of such a process, when successful, is not an "average" of the participants views, but more like a "conceptual blend" of their perspectives. According to conceptual blending, which some hypothesize to be the core algorithm of cre- ativity [FT02], new concepts are formed by combining key aspects of existing concepts — but doing so judiciously, carefully choosing which aspects to retain, so as to obtain a high-quality and useful and interesting new whole. A blend is a compact entity that is similar to each of the entities blended, capturing their "essences" but also possessing its own, novel holistic integrity.... But in the case of blending different peoples’ world-views to form something
