Debunking the Paranormal


Do you believe in ghosts? Bigfoot? Alien abductions? If you said yes to any of these, you're not alone. Many people hold beliefs about the existence of paranormal phenomona. However, many of these things cannot and have not been supported by scientific evidence. Though many people (even well respected people) claim that science can prove the existance of the phenomena, many of their arguments fall flat in the face of critical thinking. While certainly there is nothing wrong in believing in these things, its important to distinguish what science is and how it is used to discover patterns and knowledge about the world around us. Science is based on natural and predictable phenomena that can be tested. Beware of claims made by "pseudoscientists".


1. Read "A Field Guide to Critical Thinking" -

2. Choose a topic that is considered to be in the realm of the paranormal, such as alien abuctions, ESP, or ghosts. I suggest you don't choose one that you are personally committed to as it may skew your objectivity. The point of this lesson isn't to convince you either way. The point is to analyze the so-called evidence surrounding the phenemona from a scientific viewpoint and using critical thinking skills.

3. Compile a short list of claims and evidence used to support the existance of the phenomena. You can use various websites and your own knowledge base to compile this list. For instance if I was doing a report on bigfoot. Some of the claims I might list are: eyewitness accounts, footprints found, and some videotapes.

4. Write a paper that discusses the topic and its evidence and then analyze the evidence at least three areas of reasoning (from "A Field Guide to Critical Thinking".

5. Discuss ways that science could support the existance without relying on weak arguments. Use the scientific method and scientific processes to propose a research method that could support the existance of the phenomenon.

6. Your final paper should contain the discussion and the research proposal. It should be typed and include any internet sources or references you used.
