Topic: Greg Morrison. COMPUTER VIRUS JUMPS TO HUMANS. Weekly World News 21, 45 (August 1, 2000) page 75.

How do we decide whether or not a paper is credible? This is a question that one should ask about every paper we read, not just the reports from a supermarket tabloid.

  • Where was it published? Does this journal have a reputation for being careful and accurate?

    (The Weekly World News regularly carries front-page reports of UFO's, alien abductions, sightings of Bigfoot, Elvis, or Jesus, propecies of Nostradamus that just came true, and related phenomena.)

  • Who is the author? Does he have the background and qualifications appropriate to write about the topic?

    (Greg Morrison. No information.)

  • Who were the author's collaborators, sources, or advisors? Are they credible?

    (Computer expert Gary Purmon. Here we find something suspicious. The name of this "computer expert" does not show up in the World-Wide Web. Lycos Directory assistance reports no telephone listing in the United States with that surname.)

  • What citations are provided?

    (There are no formal citations. In several places the paper cites unnamed "experts" and it claims that the CDC has been studying the problem. Unfortunately, the CDC website does not confirm this study.)

  • Are there facts you know that the paper gets wrong?

    (This one seems pretty clean.)

  • Does anything seem unlikely?

    It says that 168 people have died, all over the world. One would expect to have heard of this large a problem from multiple sources, especially if so many computer experts and officials are actually aware of it.

  • Is the paper refereed?

    The only review that an article like this gets is from the editor of the paper.
