AMERICAN public attention rarely remains sharply focused upon any one domestic issue for very long—even if it involves a continuing problem of crucial importance to society. Instead, a systematic “issue-attention cycle” seems strongly to influence public attitudes and behavior concerning most key domestic problems. Each of these problems suddenly leaps into prominence, remains there for a short time, and then- though still largely unresolved—gradually fades from the center of public attention. A study of the way this cycle operates provides insights into how long public attention is likely to remain sufficiently focused upon any given issue to generate enough political pressure to cause effective change.
