Solving society’s biggest problems isn’t easy, but it can be done.With that belief, the MacArthur Foundation launched 100&Change, a competition offering a $100 million grant to a single proposal to make real progress toward solving a critical problem of our time. Applicants could focus on any critical issue, from climate change to deadly disease. By September, 7,069 competition registrants submitted 1,904 proposals. Of those, 801 passed an initial administrative review and were evaluated by a panel of expert judges who each provided ratings on four criteria: meaningfulness, verifiability, durability, and feasibility. With so many effective thinkers applying to 100&Change, it always felt as if our chances were one in a hundred—and indeed that turned out to be true. MacArthur’s Board of Directors made the final selection, whittling down 800 applicants to just eight semifinalists. To be one of these eight semifinalists is a tremendous honor. Since February 2017, we have been refining our proposal, establishing partnerships and listening to stakeholders. In the Fall of 2017, the MacArthur Board will select a smaller number of finalists, who will present their ideas in person in December. By year’s end, one group will receive the $100 million award and begin a process to spark transformational change.
