The Critical Mass Project


Building a critical mass of public support to eliminate nuclear weapons risks

Challenge

The public is largely disengaged on nuclear security and efforts to reduce nuclear risks lack political support in the United States.

Action

Research public attitudes, give advocates and storytellers tools to reframe the nuclear debate in news and popular culture, and demonstrate change is possible through timely public engagement campaigns.

Results

Increased public awareness and engagement shifts U.S. political incentives away from support for a new nuclear arms race and towards support for arms control and the elimination of nuclear weapons.

The Critical Mass project harnesses the power of storytelling and campaigns to galvanize public support for policies that reject the dangerous idea that threatening annihilation somehow makes the world safer.

Public opinion research commissioned by Critical Mass shows most people would prefer a world without nuclear weapons, but they are split on whether they believe that future is possible. An even smaller slice believes they have a role to play in creating it.

At the same time, nuclear risks are on the rise. Nuclear-armed states are investing in more weapons and new capabilities. Conflicts and nuclear threats have increased in regions with nuclear weapons. Technology is adding complexities to an already-fragile system. The world is only one mistake, miscalculation, or blunder away from a disaster that could change everything.

At another risky moment in history—the Cold War—public demand, fueled partly by popular culture, helped reduce the number of nuclear weapons in the world from 70,000 in the 1980s to 12,000 today. Now, for the first time in decades, the number of nuclear weapons in the world is projected to go up.

It doesn’t have to be this way.

Meaningful progress to reduce the nuclear threat is only possible with an engaged and informed public pushing decision makers to reduce nuclear risks and support steps toward a world without nuclear weapons.

Creative Campaigning

Critical Mass leverages cultural moments to remind people that we can make nukes history and creates cultural moments by organizing digital demonstrations of support for a world without nuclear weapons. The Project reaches the persuadable public where they get their news online and identifies ways that leaders in civil society can take action to reduce nuclear risks or protect existing policies such as the long-held U.S. moratorium on nuclear weapons testing.

Cultural Organizing 

Critical Mass engages cultural leaders to make nuclear weapons an ascendant issue. We know policy change is downstream from culture, and the stories we tell help build a critical mass of public demand to turn the tide.

The Critical Mass Pledge is a commitment from cultural leaders, including actors, directors, producers, writers, and creators, to use their craft and platforms to call attention to the dangers posed by nuclear weapons and imagine a safer future without them.
