Powerful groups often maintain their position by minimizing attention to certain issues. Policy change requires attention from policymakers and other interested participants but such attention is a rare commodity: a policymaker can only consider so many issues, a newspaper can contain only a handful of headlines and the public will only pay fleeting attention to politics. Power is exercised to make sure that important issues do not arrive at the top of the policy agenda.
