The latest trend in our quest to fix the global challenges of the 21st century is to  ‘lab’ complex issues. In short, a lab is a container for social experimentation, with a team, a process and space to support social innovation on a systemic level. These social innovation labs are popping up all over the world and are quickly acquiring star status among funders and governments. Zaïd Hassan coins the emergence of labs as a “social revolution” for its ability to tackle large challenges, such as dramatically reducing global emissions, preventing the collapse of fragile states, and improving community resilience.
