This occurs when the problem of concern is underscaled, that is that government involvement or support is low. Increased public pressure generate public policies. Government involvement is seen as a symbol of security by the public. The affected agency usually a regulatory agency tries to capture the attention of the group it is regulating. This, overscaling can sometimes lead to the end of the agency.
Nonincremental policy is also more unstable and risky.
The situation is attacked in full force not in small steps as the safe incremental policies that are used more often. Since the effect of a nonincremental policy are not known, risks are taken. Wilson notes that government is especially risk adverse because they are caught in a web of constraints so complex that any change is likely to arouse public interest. Most nonincremental policies require large amounts of money and time to be spend quickly but end results are seen later. Constituents whether it be interest groups or the public want to see results immediately.
