Indirect or delegated governance engages private organizations, tax expenditures or service users to deliver programs that would otherwise be provided by the government direct. This paper explains the rise of indirect governance in terms of policymakers’ strategic use of ‘attenuation’ to avoid political and legal challenge. Attenuation is the process by which a government obscures its role in promoting a particular policy goal, through communication strategies (attenuating rhetoric), or by utilizing private third parties and the tax system to deliver a benefit (attenuated design). Deploying policymaker interviews and an original historical database of private school choice programs and their legal and political defense, 1953-2017, I argue that pursuing both attenuated design and attenuating rhetoric at once helps policies pass and spread by publicly dissociating the government from legally contentious policy outputs.
