Aging policy is shaped by a variety of demographic, social, and economic factors. However, these factors are not the only influences on the development of public policy or aging/disability policies. Philosophical paradigms and theoretical frameworks also influence the actual development of policy and play a strong implicit role in how public policy is drafted. Values and philosophies guide the development of specific philosophical paradigms and shape how aging and disability policy is developed and implemented. This chapter explores how these realities play a role in the development and implementation of public policy and aging/disability policy. It showcases some of the realities that may prevent the implementation of the policy or program as envisioned. As a safeguard against a subjectively devised policy and program base, objective evidence and empirically driven initiatives can be developed by aging and disability policy advocates.
