A great deal of information can be obtained easily and conveniently from the web. A few key strokes on your home computer and information on almost any topic comes tumbling out at you. But as discussed in Chapter 1, we need to be selective about what information we will accept with confidence. It is important to emphasize that on the web, as Kelley (1999a) argues, "…skepticism is a required navigational aid."
When we arrive at a website that appears to be exactly what we want, we must be cautious. Is the information valid? Is it unbiased? Are there hidden sales pitches? We must be wary and skeptical of website information. Computers cannot be treated as if they are some sort of authority figures!
When we read an article in a main line scientific journal, we have reason to be confident in the information that is presented, although we must still be good skeptics and use our skills to evaluate what each article says. These journals have demanding peer-review procedures; each manuscript is read by two or three reviewers and the editor, who frequently demands revisions before accepting the paper. The acceptance rate is often less than 10% of all submissions. Thus, the reader knows there is at least the structure for quality control. Of course, authors who publish in professional journals are concerned with establishing and maintaining good professional reputations, so most will tend to be cautious about what they write and submit.With websites, however, there is no peer-review requirement, and much of the information may be anonymous. Anyone, for whatever reasons, including personal gain, can create web pages and put in any information they please. For example, advertisements on the web are not as clearly marked as they are in good quality newspapers and magazines. A web site article on a medical topic, for example, might appear to be scientific and unbiased, but actually turn out to be an advertising pitch for some commercial product that might not even be monitored by the Food and Drug Administration.
How can we evaluate the information on a web site? Kelley (1999b) makes several suggestions, a few of which are noted below.
Other ideas are found in Kelley (1999b), and the web sites listed below provide guides for reliable on-line information sources. If your computer is connected to the internet, just click on the site addresses to visit them.

In addition, most University Libraries will have guidelines and suggestions posted on their website or available as handouts in the library. Don't be afraid to ask a librarian if they have such tutorials.
