The sum of innovative acts increases the capacity of fields and entire societies to adapt to current and future challenges, and, hence, in the longer-term leads to sustainability and greater prosperity. This chapter highlights the authors' main findings, then discusses open questions for future research. Even more important moderators of social innovation than the relatively rigid institutional structures were policies and in particular perceptional frames, paving the way for or blocking an innovation’s way, for instance perceptions relating to ecology and lifestyles or solidarity (with an influence on attempts of self-organisation by and for refugees). There are some general principles, such as the ones we worked out, that act as triggers in promoting or slowing down social innovation and thereby moderate socioeconomic impact. While social innovation is hard to replicate or scale in the classical sense, these principles should be adopted to drive innovation.
