Defining problems worth solving: Design thinking practices in the problem space, data technologies, and radical innovation
研究基于欧美调查数据，发现问题空间中以同理心驱动和重新框定为核心的设计思维实践能显著促进激进创新，而数据技术虽不直接提升创新激进性，但能增强观察实践的效果。
In an era of rapid technological advancement and evolving user expectations, the paradox of choice, whereby more options reduce satisfaction, increase anxiety, and trigger decision paralysis, creates distinctive challenges for innovation. This study examines the relationship between problem-space design thinking practices, innovation radicalness, and the moderating role of data technology adoption. Analyzing survey data from Europe and the US, we find that empathy-driven, human-centered approaches significantly contribute to innovation radicalness. Reframe practices are also positively associated with innovation radicalness, whereas frame practices are not. The adoption of data technologies, although not directly related to innovation radicalness, accentuates the impact of observe and notice practices. Our findings contribute to the discourse on problemistic search by highlighting the role of empathy and reframing in challenging cognitive frames and assumptions. While data technologies, such as big data analytics, the internet of things, and artificial intelligence, can complement observe and notice practices by improving the collection of user insights, they prove less effective in supporting reframe practices for achieving innovation radicalness.
