The students were presented with subject matter that at one point or another has been characterised as pseudoscience by academics or researchers. These characterisations were made in the context of educating the public about questionable or potentially fraudulent claims and practices–efforts to define the nature of science, or humorous parodies of poor scientific reasoning. The majority of the ideas are unrealistic, and fanatical. Criticism of pseudoscience, generally by the scientific community or skeptical organisations, involves critiques of the logical, methodological, or rhetorical bases of the topic in question. Though some of the ideas continue to be investigated scientifically, others were only subject to scientific research in the past and today are considered refuted but resurrected in a pseudoscientific fashion, such as the world is flat. Other ideas presented here are entirely non-scientific, but have Ibn one way or another infringed on scientific domains or practices.
