7 And, if further justification is required in the case of the use of such a measure to help evaluate Downs's work, it must be noted that Downs was aware of the difficulty of assessing unmediated public sentiments and specifically highlighted the role played by the media in filtering this information to politicians. The related criticism, that this relationship will vary by type of issue, was specifically suggested by Downs in his formulation of the three principal characteristics of issues susceptible to issue-attention cycles, and tested for in the two articles. That the issue-attention cycle applies only to “unexciting problems” (ibid., 764) is a conclusion 1 find nowhere in Downs's work, which was directed, in the first instance, to understanding environmental problems and policy making—a subject which is far from “unexciting,” by any measure.

9 That the type of windows are not mutually exclusive would only be a concern if a strict taxonomy was being put forward. In the article, however, it is being argued that a spectrum of windows exists with major categories being placed along the spectrum. It should not be surprising, then, if some overlaps were found to exist in specific cases.

10 Case selection, of course, is a significant, related, but separate concern.
