Networks, Creativity, and Time: Staying Creative through Brokerage and Network Rejuvenation
研究发现，开放网络和异质性内容对创造力的促进作用会随时间减弱，而网络更新（新联系）能带来积极冲击，帮助个体持续获得这些优势。基于1963-2014年《神秘博士》核心艺术家的数据验证。
In this paper we adopt a dynamic perspective on networks and creativity to propose that the oft-theorized creative benefits of open networks and heterogeneous content are less likely to be accrued over time if the network is stable. Specifically, we hypothesize that open networks and content heterogeneity will have a more positive effect on creativity when network stability is low. We base our prediction on the fact that over time network stability begets cognitive rigidity and social rigidity, thus limiting individuals’ ability to make use of the creative advantages provided by open networks and heterogeneous content. On the contrary, new ties bring a positive “shock” that pushes individuals in the network to change the way they organize and process knowledge, as well as the way they interact and collaborate – a shock that enables creators to accrue the creative advantages provided by open network structures and heterogeneous content. We test and find support for our theory in a study on the core artists who worked on the TV series *Doctor Who* between 1963 and 2014.
