How to communicate large-scale social challenges: The problem of the disappearing American corporation.

Social science has distinct advantages and challenges when it comes to communicating its findings to the public. Its topics are often highly accessible to the general public, yet its findings may be counterintuitive and politically contentious.

The declining number of public corporations in the United States is associated with a shrinking middle class, lower opportunities for upward mobility, and a fraying social safety net, with important implications for individuals and public policy. Attempting to convey this set of findings to a broad public has demonstrated that some strategies and communication channels work better than others, and that some online media are particularly effective.
