Social psychology can contribute to the development of both intervention and policy; however,the path from social psychological knowledge to influencing social policy is seldom straightforward and is influenced by many factors.

This statement is true. While social psychology can inform intervention and policy development, there are many factors that can affect the translation of knowledge into action. These might include political and economic factors, competing priorities or interests, and differences in values or beliefs among people involved in policy-making. Therefore, the path to influencing social policy is often complex and may involve multiple steps and stakeholders.
