The Skeptics Society & Skeptic magazine

This lecture, traditionally the first in the series for the Skepticism 101 course, is based on the first couple of chapters from Dr. Michael Shermer’s first book, Why People Believe Weird Things, presenting a description of skepticism and science and how they work, along with a discussion of the difference between science and pseudoscience, and some very practical applications of how to test claims and evaluate evidence. The image for this lecture is the original oil painting for the first cover of Why People Believe Weird Things, commissioned by the publisher and painted by the artist Lawrence Berzon.

Skepticism 101: How to Think Like a Scientist covers a wide range of topics, from critical thinking, reasoning, rationality, cognitive biases and how thinking goes wrong, and the scientific methods, to actual claims and whether or not there is any truth to them, e.g., ESP, ETIs, UFOs, astrology, channelling, psychics, creationism, Holocaust denial, and especially conspiracy theories and how to think about them.

SCIENCE, THEORY, AND PARADIGM SHIFTS

There are three lectures in this series, they are intended to educate students about the nature of science and the power of natural explanations. This is accomplished through the concept of the Paradigm Shift. The discussion begins with non-scientific views of nature and then follows the development of scientific views and how/why they changed over many hundreds of years. This post concerns the first lecture in the series.

Examples of paradigm shifts covered in this lecture series include:

1. the shift from supernatural to nature interpretations of comets.
2. the shift from astrology (Ptolemaic) to astronomy (Copernican revolution).
3. the development of Copernican cosmology to a synthesis called Newtonian physics.
4. the shift from Newtonian physics into Relativity Theory.

Lecture 1 – PARADIGM SHIFT I

This lecture demonstrates the power of natural explanations over supernatural ones. The main topic is about the various ways that people throughout history have interpreted comets when they appeared in the sky. The lecture beings with a discussion about what we currently know about comets and then transitions into what ancients believed.

Two examples are given initially whereby major players in history misinterpreted the appearance of a famous comet (Halley’s comet) as a sign from god to fulfill their destiny. The first example was Genghis Cohn who began his invasion of the west after comet Halley appeared in the sky, the second was William the Conqueror who invaded England in 1066 after seeing comet Halley appear in the sky.

A third and final example is given whereby a person saw Halley’s comet in the sky but didn’t leap to a supernatural conclusion. This person was Sir Issac Newton and his interpretation of the comet was quite different because he assumed that the comet was natural. By asking simple, empirical, questions about the nature of the comet, Newton, with the help of Edmund Halley, was able to make a prediction the comet would one day return. Comet Halley did return just as Newton and Halley predicted thus proving that comets were not supernatural but are 100% natural just like the planets and other celestial bodies.

This book was required reading for “Why We Believe Weird Things: Science and Pseudoscience in Psychology” taught by Dr. Jeffrey Brookings and for “Parapsychology & the Occult” taught by Dr. Terence Hines.

Popular culture fills the mind with a steady diet of fantasy, from tales of UFO landings and alien abductions, haunted houses, and communication with the dead to claims of miraculous cures by spiritual healers and breakthrough treatments in ‘alternative’ medicine. The paranormal – and the pseudoscience that attempts to validate it – is so ubiquitous that many people lose sight of the distinction between the real and the imaginary, and some never learn to make the distinction in the first place. In this updated and expanded edition of “Pseudoscience and the Paranormal”, the most comprehensive and up-to-date work of its kind, psychologist and neuroscientist Terence Hines explores the question of evidence for the paranormal and delves beyond it to one that is even more puzzling: Why do people continue to believe in the reality of the supernatural despite overwhelming evidence that it does not exist? Devoting separate chapters to psychics, life after death, parapsychology, astrology, UFOs, faith healing, alternative medicine, and many other topics, Hines examines the empirical evidence supporting these popular paranormal and pseudoscientific claims. New to this edition are extended sections on psychoanalysis and pseudopsychologies, especially recovered memory therapy, satanic ritual abuse, and facilitated communication. Also included are new chapters on ‘alternative’ medicine and environmental pseudoscience. Critiquing the whole range of current paranormal claims, this carefully researched, thorough review of pseudoscience and the paranormal in contemporary life shows readers how to carefully evaluate such claims in terms of scientific evidence. This scholarly yet readable volume is an invaluable reference work for students and general readers alike. —Amazon

Do your students have the tools to distinguish between the true science of human thought and behavior from pop psychology? John Ruscio’s book provides a tangible and compelling framework for making that distinction. Because we are inundated with “scientific” claims, the author does not merely differentiate science and pseudoscience, but goes further to teach the fundamentals of scientific reasoning on which students can base their evaluation of information. John Ruscio is Associate Professor of Psychology at Elizabethtown College, where he teaches courses in Research Methods and Statistics, and Research Methods in Social Psychology. His research interests include decision-making, classification and diagnosis and taxometric methods. —Amazon

This book was required reading for the following course: “Composition” taught by Mark Gifford during the fall 2011 semester.

Legends, Lore, and Lies: A Skeptic’s Stance presents intriguing readings in five sections–urban legends, alternative medicine, the media’s role in public gullibility, psychics and the paranormal, and pseudo science–to demonstrate the importance of critical examination and the differences between an opinion or assertion and a supported claim. Legends, Lore, and Lies offers a wealth of features, including: (1) Explorations of the powers and limits of skepticism in understanding topics like urban legends and pseudoscience that often are awarded uncritical acceptance in our culture. (2) An excellent explanation of skepticism, along with a number of tools that every reader can use to become a critical consumer of information. (3) A handful of “believers” point-of-view readings, which students are encouraged to examine with the tools they acquire throughout the text. (4) A variety of pedagogical tools including brief author biographies and questions preceding and following the readings that function as writing and discussion prompts. (5) End-of-chapter synthesis questions that provide writing suggestions for longer research and inquiry papers. —Amazon

This book was required reading for Jeffrey Behm’s course, “Fantastic Archaeology” taught at the University of Wisconsin, Oshkosh during the fall 2010 semester.

Committed to the scientific investigation of human antiquity, this indispensable supplementary text uses interesting archaeological hoaxes, myths, and mysteries to show how we can truly know things about the past through science.

Examples of fantastic findings support the carefully, logically, and entertainingly described flaws in the purported evidence. By placing wildly inaccurate claims within the context of the scientific method, Frauds, Myths, and Mysteries demonstrates how science approaches fascinating questions about human antiquity and, in so doing, shows where pseudoscience falls short. —Amazon

“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

Excerpt from Syllabus

What is Science, and how is it distinguished from other aspects of human thought? Physicist Richard Feynman famously said “Science is what we do to keep from lying to ourselves”: words that get to the heart of the scientific enterprise. In an age when the activities of human society and technology can greatly affect Earth’s systems for decades, centuries, and even millennia to come, we must be able to evaluate the merits of ideas as they relate to the actual natural world, independent of our personal, political, or philosophical preconceptions. In this semester, students will learn the basic intellectual “tool kit” of the scientific enterprise. They will discuss how Science differs from other fields of human endeavor, with a particular emphasis on distinguishing scientific ideas from pseudoscientific thinking. Students will also discuss the influence of our understanding (and often misunderstanding) of Science upon contemporary society. In this course we examine real cases of Science gone bad, and the effect (good and bad) of popular portrayals of Science and scientists has on the public. We begin exploring the details of the origin, use, and effects of the energy resources which we use to run our world.

Learning Goals

By the end of the semester, every student should be able to:

• Accurately employ understanding of logical fallacies and critical thinking skills in evaluating truth claims.
• Effectively distinguish between scientific and non-scientific approaches to the understanding of the natural world.
• Identify the major energy resources used in modern society.
• Write webpages using html code, upload them to a University server, and maintain their personal website.

Excerpt from Syllabus

This course examines the key issues associated with the scientific study of critical thinking. Although it’s common to see courses on critical thinking in many domains (e.g. education & philosophy) the scientific examination of what critical thinking is and how it relates to problem solving is exclusively an advanced topic in cognitive science. Cognitive science is concerned with the study of the “thinking mind” and when we talk about “critical thinking” we base our examination on the hypothesis that while it’s true that everyone “thinks” it’s not true that everyone “thinks well.” At the core of this class is the idea that we can all fall prey to bad thinking strategies. In this course, students will learn how to be critical thinkers when dealing with a variety of situations, as well as learn how to tell the difference between science and pseudoscience. Students will focus primarily on how to think about weird situations, but if they can master the skills needed to effectively evaluate strange phenomena (e.g. UFOs) students can easily apply these skills to less bizarre situations (e.g. Will eating “Cheerios” really help lower cholesterol?). By the conclusion of this course students should be able to find answers for themselves (because everyone knows “The Truth Is Out There”) and with good critical thinking skills they will be more likely to find it.

Learning Goals

Upon completion of this course students will be able to:

1. Demonstrate scientific reading, and writing skills.
2. Apply the science of critical thinking to unique situations.
3. Discuss specific critical thinking & problem solving topics in depth.
4. Understand the biological bases of behavior and mental processes.
5. Use theories to explain and predict behavior and mental processes.

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.
