01: The Virtues of Skepticism
As the professor introduces you to the definition of skepticism and the concept behind the larger skeptical movement, learn how myths like the Hundredth Monkey Phenomenon get started, why scientists aren’t able to effectively debate pseudoscientists, and why smart people believe in what skeptics call “weird things.”
02: Skepticism and Science
What is the difference between a theory and a construct? How does skepticism relate to science? How do we know anything is true? Answer these and other questions as you explore how science works, what it means to think like a scientist, and the essential tension between skepticism and credulity.
03: Mistakes in Thinking We All Make
From coincidences and false reasoning to tautology and false analogies, there are a number of classic thinking fallacies and biases that interfere with our ability to reason clearly and rationally. This lecture provides an overview of the 12 most prevalent types of fallacies of thought that can lead us to make mistakes in our thinking.
04: Cognitive Biases and Their Effects
Once we form beliefs and commit to them, we reinforce them through powerful cognitive heuristics—otherwise known as rules of thumb or cognitive biases—that guarantee we are always correct. Explore the various types of biases we allow to influence us and learn how they can both help and hinder how we understand the world.
05: Wrong Thinking in Everyday Life
Has the status-quo effect ever led you to complacency? Have you ever held onto a stock too long because its value fell below what you paid for it? Explore the research on how people behave irrationally when it comes to money and which cognitive biases and fallacies of thought most interfere with our ability to make rational decisions about purchases and investments.
06: The Neuroscience of Belief
We all have a natural tendency to find meaningful patterns in both meaningful and meaningless noise. Learn why we’re hardwired to be superstitious and prone to making false positive errors through an investigation of the evolutionary origin of superstition and magical thinking. Discover how the brain’s neural networks drive the two central processes—patternicity and agenticity—that lead to the formation of beliefs.
07: The Paranormal and the Supernatural
According to Professor Shermer, there is no such thing as the paranormal or the supernatural. There is just the normal, the natural, and the mysteries we have yet to explain. Discover how faulty neural activity and anomalous neural firing can lead to paranormal, supernatural, and extraordinary experiences, then consider scientific explanations for these natural phenomena.
08: Science versus Pseudoscience
Who has the burden of proof in science—the person making the claim or the person hearing about the claim? Delve into human psychology, the need to believe, and the age-old techniques psychics use to lure people into believing that paranormal powers are real. Then, see how the preconceived notions of scientists can skew research results.
09: Comparing SETI and UFOlogy
What is the difference between scientists engaged in SETI—the search for extraterrestrial intelligence—and proponents of the existence of UFOs? Make a distinction between science and pseudoscience through an analysis of the supposed alien crash-landing at Roswell, physiological explanations for the experience of alien abduction, and an exploration of the attempt to answer the question “are we alone?”.
10: Comparing Evolution and Creationism
From the 1925 Scopes “Monkey” trial to the 2006 Dover trial over the theory of Intelligent Design, look at the history of the evolution and creationism debate, which has important political and cultural ramifications for science and education. Break down the “God of the Gaps” argument and consider why people shouldn’t fear evolution.
11: Science, History, and Pseudohistory
How can we tell the difference between scientific history and pseudohistory? What is the difference between historical revisionism and historical denial? Find out in this lecture that looks at the methodology of alternative historians and revisionists, specifically people who deny the Holocaust despite an overwhelming convergence of evidence. Conclude with an example of good historical science.
12: The Lure of Conspiracy Theories
Why do people believe conspiracy theories? Address the larger topic of conspiracies and conspiracy theories by contrasting erroneous claims surrounding Princess Diana’s death, the terrorist attacks of September 11, and the assassination of President Kennedy with the true conspiracy that led to the murder of Archduke Franz Ferdinand. Learn the characteristics that indicate a conspiracy theory is unlikely to be true.
13: Inside the Modern Cult
See how the power of belief and other strong psychological forces can override the rational mind and lead people to become members of cults. Learn the many characteristics that define a cult, from veneration of a leader to isolation from friends and family, then examine Heaven’s Gate as a case study for a modern cult.
14: The Psychology of Religious Belief
Investigate the issues of God, morality, and the afterlife through the eyes of a skeptic. Why do so many people across cultures believe in some form of God? What role do evolution and our cultural history play in the tendency to be religious? Look at dramatic parallels in the mythology of one religion to another as you consider the many cultural and historical factors that go into the world’s religions and their varying beliefs about God.
15: The God Question
The question of God’s existence has plagued humanity since ancient times, but it’s no less important a topic for skeptics to consider today. Using the Christian conception of God, examine the best arguments for and against his existence and judge the answer for yourself.
16: Without God, Does Anything Go?
If we hypothesize that God does not exist, is morality as we know it null and void? Consider why humans are and should be moral, independent from religion and an all-knowing God. Delve into the evolutionary theory of morality through a discussion of the Natural Law theory, the cross-cultural endorsement of the Golden Rule throughout history, and evidence of pre-moral sentiments in animals and how these gave rise to real moral emotions in humans.
17: Life, Death, and the Afterlife
Polls show that the vast majority of people believe in an afterlife. In this last lecture on science and religion, learn the primary psychological reasons why this may be the case, and consider the dualistic nature of most religions, where the soul is separate from the body. Explore biological explanations for near-death experiences—and why the events seem so real to people who report having them.
18: Your Skeptical Toolkit
Extraordinary claims require extraordinary evidence. Explore this skeptic’s motto and assemble a “skeptical toolkit” of general principles that you can use for what the late great astronomer and skeptic Carl Sagan called “the fine art of baloney detection.” Conclude with two broad observations about science and skepticism that illustrate just how important these modes of thinking are to our lives and to our society.
