“Cape Wind” is a proposed wind-energy project off the Massachusetts coast. Its environmental effects are detailed in an Environmental Impact Statement (EIS). Writers of an EIS must address rhetorical challenges posed by the complexity of how the “environment” is characterized by many statutes and regulations. These requirements include guidance on the document’s style, and because the text is hundreds of pages long, they also include rules on its arrangement (its genre), and its online delivery. Partly as a result, the writer’s stance is that of an impersonal, corporate author. The EIS is required to address multiple audiences that include decision makers and elected officials; public participation in the process is encouraged. Evidence about the actual audience shows that the public finds out about the project through media reports, web sites, and press releases, rather than studying the EIS. Finally, sustained opposition by a fossil-fuel lobbying group has led to the project’s apparent demise.

A brief business letter was written, then ten versions were madeup—each having from four to twenty-nine errors systematically introduced. Three hundred students read one version of the letter, then answered questions about the letter's contents and judged the “author” (is he intelligent, a good writer, etc.). The results pointed to misspelling as the most often noticed class of errors. Readers judged the author most harshly when spelling errors were present, but did not reach the same conclusion in the face of errors of syntax or punctuation. Finally, people labeled all classes of errors “misspelling,” and did not identify syntactic problems.
