Incrementalism And Public Policy

Incrementalism And Public Policy

Incrementalism is a model of the policy process advanced by Charles Lindblom, who views rational decision making as impossible for most issues due to a combination of disagreement over objectives and inadequate knowledge base. Policies are made instead through a pluralistic process of partisan mutual adjustment in which a multiplicity of participants focus on proposals differing only.
