This page will describe the elements of scientific writing. It will highlight the differences between popular and peer reviewed materials, and help students identify, critically analyze, and appropriately cite such materials.
Remember, the content and the type of information is far more important than where you find it or the format.
Popular scientific writing contains material written to be understood by most people without a deep educational background in the sciences. The articles, usually found in popular magazines such as Scientific American or Sky and Telescope, often have color pictures. They are usually written by journalists, and the authors do not list their academic credentials as proof of expertise. The content is often an overview of a topic, and does not attempt to be comprehensive. There are rarely citations within the articles, and rarely does the article end with References to the literature. There may be Recommended Readings for finding out more about the topic, and these are frequently books on the topic.
Information found on the Internet through open searches: The web provides high quality information from professional associations, societies, and academic institutions. However, the web also contains sites which provide false, misleading, and outrageous content; and some sites appear authoritative but are really only presenting the portion of the material that supports their positions. Everything is written for a purpose, so be alert in order to identify misleading information. Beware of sensational "entertainment" pieces, slanted news from biased sources, and vanity press material with little factual basis. Readers must be very critical about the validity of these materials; always look for evidence of reliability such as author credentials, organizational credentials, balanced and reliable references that support the ideas and positions presented, and review the currency of the material used for support.

Trade publications are industry newsletters that provide important news and industry overviews for managers and researchers. Even though they may be written by subject experts, they do not go through the "peer review" process - and therefore should not be considered scholarly publications. These materials assume a deep understanding of the field. They do not contain many references to prior research or citations to supporting information.
Scientific writing is intended for other researchers in a field, and assumes a significant amount of prior knowledge in the field.
Scientific manuscripts are submitted for peer review (review for accuracy by other experts) before they are accepted for publication. Scientific journals utilize editorial boards and volunteer peer reviewers to control the quality of accepted material. Scientific journals may contain a mix of peer reviewed articles, review articles, letters to the editor, and editorials. Be sure to determine which type of material you are reading.
Scientific peer review articles contain specific elements and characteristics:
Even though scientific articles have passed through a rigorous peer review process, one must be careful and critical when reading such documents. More current investigations and findings may update or invalidate earlier findings. (Remember to sort your results by date to have the most recent articles appear first.) Some articles contain errors and you may see errata (correction) reports or retractions. These initial reports of methods and findings are referred to as Primary Literature. Often other experts will submit follow-up Comments and /or Letters to the Editor.
On occasion, experts will write Review articles which provide a state-of-the-art update for a field. This synthesis of previous work can help new researchers in a field become familiar with the current trends, names, and theories in a discipline. These reviews of primary research reports are called Secondary Literature, and they have great value; but do not mistake them for the original Primary Research articles that contain the full details of experiments with the elements mentioned above.
Errors: Errors in analysis, samples, interpretations, or conclusions can be discovered and recorded after publication as Errata. These modifications to the original works are often included in search results and are entered as Errata links on the database or index article abstract page. See the Retraction Watch database of retractions. See a sample: Errata to "Coronal Alignment of the Lower Limb and the Incidence of Constitutional Varius Knee in Korean Females"
Improper Behavior: On occasion, some researchers have falsified data or conclusions. This can end a career and jeopardize the future of an organization. See the following example of falsifying lab note books, falsifying lab results, etc. Crucial Data Were Fabricated In Report Signed by Top Biologist. See the tutorial at the bottom of the page for additional information.
