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.

Dr. Michael Shermer considers the characteristics of cults, how they differ from sects, religions, and myths, the role that myths and religions play in culture and people’s lives, and what Scientologists really believe.

Dr. Michael Shermer reviews the many ways that our attempts to understand the truth about the world are derailed by cognitive biases, including the anchoring bias, the representative bias, the availability bias, the confirmation bias, the hindsight bias, the self-serving bias, and even the bias bias.

This lecture is part of a course that Dr. Shermer teaches at Chapman University called Skepticism 101: How to Think Like a Scientist which 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.

Conspiracy Detection Kit

Parallel to my Baloney Detection Kit, I have put together a 10-point list for a Conspiracy Detection Kit. The more that a conspiracy theory manifests the following characteristics, the less likely it is to be a real conspiracy.

1. Patternicity. Proof of the conspiracy supposedly emerges from a pattern of “connecting the dots” between events that need not be causally connected. When no evidence supports these connections except the allegation of the conspiracy, or when the evidence fits equally well to other patterns—or to randomness—the conspiracy theory is likely false.
2. Agenticity. The agents behind the pattern of the conspiracy would need nearly superhuman power to pull it off. Most of the time in most circumstances, people, agencies, and corporations are not nearly so powerful as we think they are. If the conspiracy theory involves super powerful agents it is likely false.
3. Complexity. The conspiracy theory is complex and its successful completion demands a large number of elements coming together at just the right moment and in the proper sequence. The more elements involved and the more delicate the timing of the sequence in which they must come together, the less likely the conspiracy theory is to be true.
4. People. The more people involved in the conspiracy theory the less likely it is to be true. Conspiracies involving large numbers of people who would all need to keep silent about their secrets typically fail. People are incompetent and emotional. They screw up, chicken out, change their minds, have moral scruples. Conspiracy theories treat people like programmed robots carrying out their commands. That is unrealistic.
5. Grandiosity. If the conspiracy theory encompasses some grandiose ambition for control over a nation, economy, or political system, and especially if it aims for world domination, it is almost certainly false. The bigger the conspiracy the more likely it is to fail for the reasons of complexity and people that I’ve just given.
6. Scale. When the conspiracy theory ratchets up from small events that might be true to much larger events that have much lower probabilities of being true, it is very likely false. Most real conspiracies involve very specific events and targets, such as insider trading on Wall Street, price fixing in an industry, tax evasion by a corporation, and, yes, the assassination of a political leader, but always for a narrow goal of making money, grabbing power, or ending tyranny.
7. Significance. If the conspiracy theory assigns portentous and sinister meanings and interpretations to apparently innocuous or insignificant events, it is most likely false. Again, most conspiracies are narrowly focused and significant only to those who will benefit or be hurt. Most real conspiracies do not change the world.
8. Accuracy. If the conspiracy theory commingles facts and speculations without distinguishing between the two, it is likely to be false. Conspiracists are notorious for sprinkling in a handful of verifiable facts amidst a vast array of conjectures and suppositions, which blur reality and confuse listeners into thinking there is more to the theory than there actually is.
9. Paranoia. If a conspiracy theorist is extremely and indiscriminately suspicious of any and all government agencies or private corporations, this suggests a lack of nuance in understanding how the world works. Yes, sometimes “they” really are out to get you, but usually not.
10. Falsifiability. Conspiracy theorists typically refuse to consider alternative explanations, rejecting all disconfirming evidence for the theory, and blatantly seeking only confirming evidence to support what has a priori been determined as the truth. To return to Karl Popper, if a conspiracy theory cannot be falsified, it is probably false.

The James Randi Educational Foundation has produced a superb 10-part video lecture series in which Harriet Hall, M.D., contrasts science-based medicine with so-called “complementary and alternative” methods. The topics include: What is CAM?; acupuncture; chiropractic; energy medicine; homeopathy; miscellaneous “alternatives”; naturopathy and herbal medicines; pitfalls in research; science based medicine vs. evidence-based medicine; science-based medicine in the media and politics. The lectures range from 32 to 45 minutes. A companion course guide is also available. Listen to the audio advertisement for the course. Listen to the audio advertisement for the course.

Volume 1: Advertising the Con Academy

This is the first video in a series featuring Michael Shermer and Brian Dalton (aka: Mr. Deity). The mission of these videos is to promote critical thinking through the use of humor, wit, and satire.

In this faux commercial for The Con Academy you’ll see how psychics count on the confirmation bias to convince people that their powers are real when, in fact, they are just remembering the hits and forgetting the misses. We also demonstrate how psychic “organizations” con people by taking their money for services that are not real.

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

Excerpt from Syllabus

Paranormal beliefs are important, widespread and yet rarely studied. The analysis of those beliefs is both valuable in itself and useful in developing critical and analytical skills. Since both skepticism and the paranormal are defined in relation to science, and are often strongly influenced by science, some elucidation of the nature of science and of its position in society is required. Modern skepticism the science-inspired study of paranormal claims relates both to science and to the paranormal, and seeks to influence media coverage of these issues.

The course aims to elucidate the nature of the three terms in the title and, through the lectures and the seminars, to enable the students to evaluate paranormal claims in skeptical terms. Both the seminars and the take-home exam encourage students to apply skeptical concepts to the paranormal, and to arrive at their own conclusions. The multiple choice examination encourages broad comprehension of key concepts.

Learning Goals

After successfully completing this course students should be able to:

1. Understand the nature of skepticism, science and the paranormal and their places in western societies, as shown in an ability to outline their key attributes.
2. Understand the intellectual tools of modern skepticism, their ethical dimensions and their applicability to paranormal claims, as shown by an ability to outline these and instance their application to specific cases.
3. Have the ability to apply skeptical criteria to selected paranormal and related claims.
4. Have the capacity to present the results of analysis in well-structured and logical form.

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.
