      A for‐profit status also affects the way authors present information in an article. Editors want to catch the attention of readers, so they will place the most sensational or provocative information in the headline or first paragraph. This structure is called pyramid writing, and journalists use it because they know that most people won't read to the end of the article. If 100% of readers read the headline, about 70% will read the introductory paragraph, and only 50% will read through to the fourth paragraph (O'Connor, 2002, p. 117). Therefore, qualifications that some results do not reinforce a certain conclusion, or that more research is needed to confirm a hypothesis, may receive only brief mention and appear at the end of the article.

Because of the desire to provoke readers and sell more issues, popular sources can sometimes publish pseudoscience. What is pseudoscience? Etymologically, the word means “fake science”; however, it is not subject to a simple or easy definition. For example, you cannot merely state that real science is neutral and objective whereas pseudoscience is biased and subjective. Nor can you argue that real science always follows the scientific method, but that pseudoscience is sloppy. And you also cannot argue that pseudoscience results from a specific political agenda, and real science is separate from politics. So, what makes some studies “fake” and others “real”?

      There are some guidelines you can use to determine whether a study is pseudoscience. In pseudoscience, as with science, you want to evaluate the content of a study and the publication in which the study appears. If you can determine that the study is published in a scholarly source, it is less likely to be pseudoscience.

A working knowledge of logical fallacies can also be useful for separating science from pseudoscience. The phrase logical fallacy describes a position that is logically untenable. If a writer uses unsound thinking to support a hypothesis, it can lead to an invalid conclusion. There are a number of different logical fallacies, but in Table 3.1 we describe only those more relevant to identifying pseudoscience. You can find a more detailed exploration of logical fallacies at: http://www.fallacyfiles.org.

Table 3.1 Logical Fallacies

Fallacy	How It works	Example
Emotionally loaded terms	Appeals to a reader's emotions without using logic or other support to back up the argument	If you really cared about children, you would vote for the pro‐life candidate.
Bandwagon fallacy	Argues that, because everyone else thinks or acts a certain way, the reader should as well	The candidate won with a huge majority of votes, so she must be very qualified.
Faulty cause and effect	Sets up a cause–effect relation without evidence that the two events are causally related	As more homes have televisions, literacy rates have decreased; therefore, an increase in televisions causes a decrease in literacy rates.
Either/or reasoning (also a black and white fallacy or false dichotomy)	Presents a situation as having only two alternatives	Either aggression levels are biologically determined or they are caused by environmental factors.
Hasty generalization	Develops a conclusion or rule based on only an individual case or a few cases	This study shows that college students scored well on the test; therefore all 18‐ to 21‐year‐olds would score well.

      The presence of a logical fallacy does not necessarily invalidate all the work done in a study; however, fallacies are warning signs that there might be other weaknesses in the research. Additional items to look for when evaluating a source's credibility are unexplained or unacknowledged contradictions, persuasion with creative or strong language rather than valid evidence, the presence of jargon that other scientists do not use, and the lack of reliable sources that support the hypothesis and conclusion.

      For scholarly examinations of pseudoscience, see Pigliucci (2010), Leahy (1983), Lilenfeld, Lohr, and Morier (2001), Still and Dryden (2004), Olatunji, Parker, and Lohr (2005/2006). There are also websites that explore various kinds of pseudoscience. Some examples are:

Evaluating Internet Sources

      For a paper about serial killers, the following four sources are relevant:

      1 Wikipedia has an entry on serial killing at http://en.wikipedia.org/wiki/Serial_killer.

      2 Through Google Scholar you can find an article titled “Predicting serial killers' home base using a decision support system” by David Canter, Toby Coffey, Malcolm Huntley and Christopher Missen in Journal of Quantitative Criminology.

      3 Through PsycINFO you can find “Critical characteristics of male serial murderers” by William B. Arndt, Tammy Hietpas, and Juhu Kim in American Journal of Criminal Justice.

      4 A Yahoo search with the key words “serial killer psychology” connected you to a page on the Crime Museum's website: https://www.crimemuseum.org/crime‐library/serial‐killers.

      Which source(s) will be useful and credible for an academic paper on serial killers? Which source(s) would increase your reader's confidence in your ideas? Use the following points to assess the sources.

       Using sources written by psychologists for psychologists may strengthen the credibility of your paper.

       Using sources that appear in an academic publication may strengthen the credibility of your paper.

       Using sources that are NOT written by psychologists for psychologists may indicate to your reader that you were too lazy to look for scholarly sources.
