Skeptic: Examining Extraordinary Claims and Promoting Science

This course was taught at the University of Texas at El Paso during the spring 2013 semester.

Excerpt from Syllabus

This course is designed to introduce students to a variety of critical thinking skills and to encourage them to practice those skills in the context of evaluating popular claims, especially extraordinary claims about topics relevant to anthropology and archeology. It is intended for students who are attracted to the interesting topics identified with anthropology in the popular media, but the level of instruction assumes no prior experience in anthropology. Students will learn about the methods used to interpret the physical traces of behavior, and how to distinguish scientific arguments from pseudoscience and non-science. Lectures, readings and class exercises will examine a variety of non-scientific explanations for past and present events, such as UFOs and ancient astronauts, Bigfoot, pyramid power, Atlantis, creationism and intelligent design, the Book of Mormon, dowsing, climate change denial, and psychic archeology.

Does Bigfoot roam the mountains of Oregon, and do his cousins hang out in the Sacramento Mountains of southern New Mexico? Are they shape-shifters, or do they use wormholes to travel the time-space continuum? Are extraterrestrial aliens like the ones who crashed in Roswell, New Mexico silvers or greens? Is there really an exotic blood-sucking animal called chupacabra killing livestock in the southern U.S. and northern Mexico, or is it just a hairless raccoon? Should we believe Senator James Inhofe when he says that global climate change is a hoax? Is cell phone use harmful to your health? Do the Power Balance bracelets worn by Drew Brees and Kobe Bryant provide any real scientific advantage to athletes? Are modern humans related to ancient prehistoric peoples, or were we created in modern form? Is there reliable evidence to support the claims that psychics can reveal details about the past or make valid predictions about the future? Was planet earth really visited by ancient astronauts, and did they teach Egyptians how to build the pyramids? How can we know the answers to such questions? In fact, how can we know the truth about any claim? We are bombarded by information and claims all the time, and it is vitally important, now more than ever, that we be able to distinguish valid information and warranted conclusions from those that are not. How can we do this, especially when the claims involve events that occurred in the prehistoric past, were not witnessed by humans, or were not documented in written records?

Excerpt from Syllabus

One of the characteristics of contemporary American popular discourse is a marked increase in irrationalism. Belief in the paranormal, pseudoscience, and millenialism is perhaps more prevalent than at any other time in the history of Western Civilization. This course seeks to test these beliefs through the application of rhetorical analysis and critical thinking to discourse advancing extraordinary claims.

Learning Goals

Upon successful completion of this course, the students will be able to:

1. Identify extraordinary claims in popular discourse.
2. Identify the types of appeals, including forms of reasoning and evidence, used to advance extraordinary claims in popular discourse.
3. Assess the strength of rhetoric advancing extraordinary claims.
4. Prepare critical analyses and refutations of rhetoric advancing extraordinary claims.

This book was required reading for Jeffrey Brookings’ course, “Why We Believe Weird Things: Science and Pseudoscience in Psychology” taught at Wittenberg University during the fall 2010 semester.

They are tiny. They are tall. They are gray. They are green. They survey our world with enormous glowing eyes. To conduct their shocking experiments, they creep in at night to carry humans off to their spaceships. Yet there is no evidence that they exist at all. So how could anyone believe he or she was abducted by aliens? Or want to believe it?

To answer these questions, psychologist Susan Clancy interviewed and evaluated “abductees”–old and young, male and female, religious and agnostic. She listened closely to their stories–how they struggled to explain something strange in their remembered experience, how abduction seemed plausible, and how, having suspected abduction, they began to recollect it, aided by suggestion and hypnosis.

Clancy argues that abductees are sane and intelligent people who have unwittingly created vivid false memories from a toxic mix of nightmares, culturally available texts (abduction reports began only after stories of extraterrestrials appeared in films and on TV), and a powerful drive for meaning that science is unable to satisfy. For them, otherworldly terror can become a transforming, even inspiring experience. “Being abducted,” writes Clancy, “may be a baptism in the new religion of this millennium.” This book is not only a subtle exploration of the workings of memory, but a sensitive inquiry into the nature of belief. —Amazon

This book was required reading for the following courses: (1) “Science, Skepticism & Weird Behavior” taught by Bryan Lovelace, (2) “Skepticism & the Scientific Worldview” taught by Travis Knowles, (3) “Skepticism, Science & the Paranormal” taught by Martin Brigdstock, and (4) “The Scientific Method: Critical & Creative Thinking” taught by Stephen Sekula et al.

This brief text helps students to think critically, using examples from the weird claims and beliefs that abound in our culture to demonstrate the sound evaluation of any claim. It explains step-by-step how to sort through reasons, evaluate evidence, and tell when a claim (no matter how strange) is likely to be true. The emphasis is neither on debunking nor on advocating specific assertions, but on explaining principles of critical thinking that enable readers to evaluate claims for themselves. The authors focus on types of logical arguments and proofs, making How to Think about Weird Things a versatile supplement for logic, critical thinking, philosophy of science, or any other science appreciation courses.—Amazon

James Randi calls this textbook, “the most powerful, comprehensive, and readable collections of examples, explanations and caveats that I could have ever hoped for.” A library must!—Skeptic

This book was required reading for the following courses: (1) “Skepticism 101: How to Think Like a Scientist Without Being a Geek” taught by Michael Shermer, (2) “Weird Science” taught by John Donovan, (3) “The Scientific Method: Critical & Creative Thinking” taught by Stephen Sekula et al., and (4) “Studies in Behavior: Critical Thinking” taught by Evelyn Buday.

“The great astronomer and science writer challenges New Agers and explains social phenomena like UFOs, alien abductions, recovered memories, satanic cults, witch crazes, hallucinations, and how to detect baloney. This is Sagan’s most popular book among skeptics, filled with quotable maxims, popular among college professors as a supplemental text for students, but a classic for everyone who cares about living in a sane and safe world without superstition.” —Skeptic

“Eminent Cornell astronomer and bestselling author Sagan debunks the paranormal and the unexplained in a study that will reassure hardcore skeptics but may leave others unsatisfied. To him, purported UFO encounters and alien abductions are products of gullibility, hallucination, misidentification, hoax and therapists’ pressure; some alleged encounters, he suggests, may screen memories of sexual abuse. He labels as hoaxes the crop circles, complex pictograms that appear in southern England’s wheat and barley fields, and he dismisses as a natural formation the Sphinx-like humanoid face incised on a mesa on Mars, first photographed by a Viking orbiter spacecraft in 1976 and considered by some scientists to be the engineered artifact of an alien civilization. In a passionate plea for scientific literacy, Sagan deftly debunks the myth of Atlantis, Filipino psychic surgeons and mediums such as J.Z. Knight, who claims to be in touch with a 35,000-year-old entity called Ramtha. He also brands as superstition ghosts, angels, fairies, demons, astrology, Bigfoot, the Loch Ness monster and religious apparitions. (Feb.)” —Publishers Weekly

In this age of scientific enlightenment, many people still believe in mind reading, past-life regression theory, New Age hokum, and alien abduction. A no-holds-barred assault on popular superstitions and prejudices, Why People Believe Weird Things debunks these nonsensical claims and explores the very human reasons people find otherworldly phenomena, conspiracy theories, and cults so appealing. Michael Shermer takes on science luminaries like physicist Frank Tippler and others, who hide their spiritual beliefs behind the trappings of science.

Shermer, science historian and true crusader, also reveals the more dangerous side of such illogical thinking, including Holocaust denial, the recovered-memory movement, the satanic ritual abuse scare, and other modern crazes. Why People Believe Weird Things is an eye-opening resource for the most gullible among us and those who want to protect them.

Excerpt from Syllabus

In its broadest sense, Fantastic Archaeology describes those claims and interpretations about the archaeological record that are outside the orthodox mainstream of the scholarly and professional world of archaeology. This can range from new, as yet untested hypotheses that may become the orthodox interpretations to the outrageous claims that can be easily refuted. Students will examine this entire range of competing, non-orthodox interpretations of the archaeological record.

This course has a much broader subject area than students are likely to encounter in other courses–even in an eclectic field like Anthropology. Students have the opportunity to bring knowledge and expertise acquired in other courses, or their general life experience, to the discussions.

Excerpt from Syllabus

“Vaccines cause autism.” “Playing Mozart to infants increases their intelligence.” “Prayer cures cancer.” These and other sensational claims are reported daily by the popular media, who usually present them as factual because there is—purportedly—scientific evidence of their validity. But what qualifies as scientific evidence, and how do we distinguish scientifically-supported conclusions from plausible-sounding but unsubstantiated, untestable assertions? In this course, we begin by defining what science is and how it differs from pseudoscience. We then consider the basic perceptual and cognitive mechanisms through which humans gather and process information, emphasizing errors in thinking and reasoning that, despite scientific evidence to the contrary, predispose us to believe, “weird” things.

Finally, we will use what we have learned to investigate phenomena of particular interest to behavioral scientists and paranormal investigators, including subliminal perception and persuasion, astrology, near death experiences, criminal profiling, alien abduction stories, repressed memories, and “new” psychotherapies. Our goal is to be open to novel claims, coupled with the determination to subject those claims to careful scientific scrutiny.

Learning Goals

In this class, students will:

1. Learn how science and pseudoscience differ, and why the difference matters.
2. Explore human perception, cognition, memory, and emotion, including errors and biases that lead us to believe “weird things.”
3. Develop tools for conducting skeptical analyses of extraordinary claims.
4. Sharpen writing and oral presentation skills.
5. Design, complete, and present an investigation of an extraordinary claim.
6. Lay the foundation for a successful college experience.

Excerpt from Syllabus

This comprehensive course on science and skepticism will address the most mysterious, controversial, and contentious issues in science and skepticism from a quarter century of research involving: science and pseudoscience, science and pseudohistory, science and religion, science and morality, the psychology and neuroscience of belief, science and politics, science and economics, evolution and intelligent design creationism, the Baloney Detection Kit, how beliefs can be changed, how science works (and sometimes doesn’t work) from the history of science, and many specific examples of the power of belief.

Using numerous examples from three decades of research on this subject, students will learn how to think scientifically and skeptically, and he will show how to be open-minded enough to accept new ideas without being so open-minded that their brains fall out. This course meets once a week for three hours and includes lectures accompanied by in-class demonstrations, videos, magic, illusions, and examples from pop culture, along with rigorous scientific research, plus student discussions and presentations.
