ABSTRACT
Figures 2.1 and 2.2 are both Web pages that might be retrieved using one of the general Web search engines. Both pages have important messages to convey, yet there are striking differences in how effectively these messages are presented. Figure 2.1, a section from a Web Page entitled “Sex Differences in Children’s Behavior: Genetics or Environment?,” describes the results of research on sex differences in the behavior of rhesus monkeys. Although the information appears to be valid, there is no easy way to determine the information’s attribution and reliability, for the following reasons:
• No author is given for the work, and there is no link to a home page that might identify the author and his or her qualifications. As a result, we have no way of knowing whether the author is a scholar in the field or a student writing a term paper.
