Then he uses an appeal to authority by quoting a chemistry professor at Columbia University, Dr. Harold Urey, who said, "All of us who study the origin of life find that the more we look into it, the more we feel it is too complex to have evolved anywhere." That's a patently absurd, baseless evidence. Number 13 -- Slippery Slope. Blair Magida Waddick writes to the Chicago Tribune that he

Appeal to Authority In one advertisement for a skincare product, the company claimed “most dermatologists recommend...” the product. This is an appeal to authority: a classic logical fallacy. With an appeal to authority like this one, the speaker bases its claim solely on the authority of an individual or institution.

Because fallacies like the ones presented above can cause such problems in all forms of research and decision making, it is useful to have some tools to analyze a given statement. Known as "analytical tools," some examples are the "Devils Advocate," a method in which one argues against the stated conclusion to determine its validity (even though one may not agree with the position), "Lateral Thinking," or Edward de Bono's

Fallacies The choices that people make determine the shape of things to come. This observation holds true at the individual, organizational, national, and global level. Therefore, it is obvious that close attention needs to be paid to critical thinking ability or the way decisions are made. This inference can be drawn because critical thinking involves the formation of logical inferences, the development of cohesive and logical reasoning patterns, and careful and
