Best-selling author Michael Shermer presents an overarching theory of conspiracy theories-who believes them and why, which ones are real, and what we should do about them. Nothing happens by accident, everything is connected, and there are no coincidences: that is the essence of conspiratorial thinking. Long a fringe part of the American political landscape, conspiracy theories are now mainstream: 147 members of Congress voted in favor of objections to the 2020 presidential election based on an unproven theory about a rigged electoral process promoted by the mysterious group QAnon. But this is only the latest example in a long history of ideas that include the satanic panics of the 1980s, the New World Order and Vatican conspiracy theories, fears about fluoridated water, speculations about President John F. Kennedy's assassination, and the notions that the Sandy Hook massacre was a false-flag operation and 9/11 was an inside job. In Conspiracy, Michael Shermer presents an overarching review of conspiracy theories-who believes them and why, which ones are real, and what we should do about them. Trust in conspiracy theories, he writes, cuts across gender, age, race, income, education level, occupational status-and even political affiliation. One reason that people believe these conspiracies, Shermer argues, is that enough of them are real that we should be constructively conspiratorial: elections have been rigged (LBJ's 1948 Senate race); medical professionals have intentionally harmed patients in their care (Tuskegee); your government does lie to you (Watergate, Iran-Contra, and Afghanistan); and, tragically, some adults do conspire to sexually abuse children. But Shermer reveals that other factors are also in play: anxiety and a sense of loss of control play a role in conspiratorial cognition patterns, as do certain personality traits. This engaging book will be an important read for anyone concerned about the future direction of American politics, as well as anyone who's watched friends or family fall into patterns of conspiratorial thinking.

Aliens. Ley lines. Water dowsing. Conspiracies and myths captivate imaginations and promise mystery and magic. Whether it's arguing about the moon landing hoax or a Frisbee-like Earth drifting through space, when held up to science and critical thinking, these ideas fall flat. In Weird Earth: Debunking Strange Ideas About Our Planet, Donald R. Prothero demystifies these conspiracies and offers answers to some of humanity's most outlandish questions. Applying his extensive scientific knowledge, Prothero corrects misinformation that con artists and quacks use to hoodwink others about geology-hollow earth, expanding earth, and bizarre earthquakes-and mystical and paranormal happenings-healing crystals, alien landings, and the gates of hell. By deconstructing wild claims such as prophesies of imminent natural disasters, Prothero provides a way for everyone to recognize dubious assertions. Prothero answers these claims with facts, offering historical and scientific context in a light-hearted manner that is accessible to everyone, no matter their background. With a careful layering of evidence in geology, archaeology, and biblical and historical records, Prothero's Weird Earth examines each conspiracy and myth and leaves no question unanswered.

The battles over evolution, climate change, childhood vaccinations, and the causes of AIDS, alternative medicine, oil shortages, population growth, and the place of science in our country-all are reaching a fevered pitch. Many people and institutions have exerted enormous efforts to misrepresent or flatly deny demonstrable scientific reality to protect their nonscientific ideology, their power, or their bottom line. To shed light on this darkness, Donald R. Prothero explains the scientific process and why society has come to rely on science not only to provide a better life but also to reach verifiable truths no other method can obtain. He describes how major scientific ideas that are accepted by the entire scientific community (evolution, anthropogenic global warming, vaccination, the HIV cause of AIDS, and others) have been attacked with totally unscientific arguments and methods. Prothero argues that science deniers pose a serious threat to society, as their attempts to subvert the truth have resulted in widespread scientific ignorance, increased risk of global catastrophes, and deaths due to the spread of diseases that could have been prevented.

This academic text features articles regarding paranormal, extraordinary, or fringe-science claims. It logically examines the claims of astrology; psychic ability; alternative medicine and health claims; after-death communication; cryptozoology; and faith healing, all from a skeptical perspective. Paranormal Claims is a compilation of some of the most eye-opening articles about pseudoscience and extraordinary claims that often reveal logical, scientific explanations, or an outright scam. These articles, steeped in skepticism, teach critical thinking when approaching courses in psychology, sociology, philosophy, education, or science.

Who is the 'Devil'? And what is he due? The Devil is anyone who disagrees with you. And what he is due is the right to speak his mind. He must have this for your own safety's sake because his freedom is inextricably tied to your own. If he can be censored, why shouldn't you be censored? If we put barriers up to silence 'unpleasant' ideas, what's to stop the silencing of any discussion? This book is a full-throated defense of free speech and open inquiry in politics, science, and culture by the New York Times bestselling author and skeptic Michael Shermer. The new collection of essays and articles takes the Devil by the horns by tackling five key themes: free thought and free speech, politics and society, scientific humanism, religion, and the ideas of controversial intellectuals. For our own sake, we must give the Devil his due.

Throughout our history, humans have been captivated by mythic beasts and legendary creatures. Tales of Bigfoot, the Yeti, and the Loch Ness monster are part of our collective experience. Now comes a book from two dedicated investigators that explores and elucidates the fascinating world of cryptozoology.

Daniel Loxton and Donald R. Prothero have written an entertaining, educational, and definitive text on cryptids, presenting the arguments both for and against their existence and systematically challenging the pseudoscience that perpetuates their myths. After examining the nature of science and pseudoscience and their relation to cryptozoology, Loxton and Prothero take on Bigfoot; the Yeti, or Abominable Snowman, and its cross-cultural incarnations; the Loch Ness monster and its highly publicized sightings; the evolution of the Great Sea Serpent; and Mokele Mbembe, or the Congo dinosaur. They conclude with an analysis of the psychology behind the persistent belief in paranormal phenomena, identifying the major players in cryptozoology, discussing the character of its subculture, and considering the challenge it poses to clear and critical thinking in our increasingly complex world.

Alfred Russel Wallace was the co-discoverer with Darwin of evolution by natural selection, and one of the leading natural history explorers of the 19th century. He was a multifaceted scientist, with deep interests in spiritualism, and a surprising naive streak running through his scientific interests, parallel with scientific contributions of the highest probity and importance. In In Darwin's Shadow, Michael Shermer captures all the aspects and facets of Wallace's life and personality.

A psychiatrist presents a compelling argument for how human purpose and caring emerged in a spontaneous and unguided universe. Can there be purpose without God? This book is about how human purpose and caring, like consciousness and absolutely everything else in existence, could plausibly have emerged and evolved unguided, bottom-up, in a spontaneous universe. A random world--which according to all the scientific evidence and despite our intuitions is the actual world we live in--is too often misconstrued as nihilistic, demotivating, or devoid of morality and meaning. Drawing on years of wide-ranging, intensive clinical experience as a psychiatrist, and his own family experience with cancer, Dr. Lewis helps readers understand how people cope with random adversity without relying on supernatural belief. In fact, as he explains, although coming to terms with randomness is often frightening, it can be liberating and empowering too. Written for those who desire a scientifically sound yet humanistic view of the world, Lewis's book examines science's inroads into the big questions that occupy religion and philosophy. He shows how our sense of purpose and meaning is entangled with mistaken intuitions that events in our lives happen for some intended cosmic reason and that the universe itself has inherent purpose. Dispelling this illusion, and integrating the findings of numerous scientific fields, he shows how not only the universe, life, and consciousness but also purpose, morality, and meaning could, in fact, have emerged and evolved spontaneously and unguided. There is persuasive evidence that these qualities evolved naturally and without mystery, biologically and culturally, in humans as conscious, goal-directed social animals. While acknowledging the social and psychological value of progressive forms of religion, the author respectfully critiques even the most sophisticated theistic arguments for a purposeful universe. Instead, he offers an evidence-based, realistic yet optimistic and empathetic perspective. This book will help people to see the scientific worldview of an unguided, spontaneous universe as awe-inspiring and foundational to building a more compassionate society.

In The Borderlands of Science, Michael Shermer takes us to the place where real science, borderline science--and just plain nonsense--collide. Shermer argues that science is the best lens through which to view the world, but recognizes that it's often difficult to tell where valid science leaves off and borderland, or fuzzy science begins. To solve this dilemma, Shermer looks at a range of topics that put the boundary line in high relief. For instance, he debunks the many "theories of everything" that try to reduce the complexity of the world to a single principle. He examines the work of Darwin and Freud, explaining why one is among the great scientists in history, while the other has become nothing more than a historical curiosity. And he reveals how scientists themselves can be led astray, as seen in the infamous Piltdown hoax-the set of ancient hominid bones found in England that after decades turned out to be a forgery.

From SETI and acupuncture to hypnosis and human cloning, this enlightening volume will help readers stay grounded in common sense amid the flurry of supposedly scientific theories that inundate us every day.

"Shermer is savage about the shortcomings of intelligent design
and eloquent about the spirituality of science . . . An invaluable primer."
--"Los Angeles Times Book Review""" Science is on the defensive. Half of Americans reject the theory of evolution and intelligent-design campaigns are gaining ground. Classroom by classroom, creationism is overthrowing biology. In "Why Darwin Matters," bestselling author Michael Shermer decodes the scientific evidence to show that evolution is not "just a theory" and illustrates how it achieves the design of life through the bottom-up process of natural selection. Shermer, once an evangelical Christian and a creationist, argues that intelligent-design proponents are invoking a combination of bad science, political antipathy, and flawed theology. He refutes their pseudoscientific arguments and then demonstrates why conservatives and people of faith can and should embrace evolution. Cutting the politics away from the facts, "Why Darwin Matters" is an incisive examination of what is at stake in the debate over evolution.

Synthesizing thirty years of research, psychologist and science historian, Michael Shermer upends the traditional thinking about how humans form beliefs about the world. Simply put, beliefs come first and explanations for beliefs follow. The brain, Shermer argues, is a belief engine. Using sensory data that flow in through the senses, the brain naturally looks for and finds patterns - and then infuses those patterns with meaning, forming beliefs. Once beliefs are formed, our brains subconsciously seek out confirmatory evidence in support of those beliefs, which accelerates the process of reinforcing them, and round and round the process goes in a positive-feedback loop. In The Believing Brain, Shermer provides countless real-world examples of how this process operates, from politics, economics, and religion to conspiracy theories, the supernatural, and the paranormal. Ultimately, he demonstrates why science is the best tool ever devised to determine whether or not our belief matches reality.

"Denying History" takes a bold and in-depth look at those who say the Holocaust never happened and explores the motivations behind such claims. While most commentators have dismissed the Holocaust deniers as antisemitic neo-Nazi thugs who do not deserve a response, historians Michael Shermer and Alex Grobman have immersed themselves in the minds and culture of these Holocaust "revisionists." In the process, they show how we can be certain that the Holocaust happened and, for that matter, how we can confirm any historical event. This edition is expanded with a new chapter and epilogue examining current, shockingly mainstream revisionism.

Two controversial authors debate the nature and methods of science, its dogmas, and its future. Rupert Sheldrake argues that science needs to free itself from materialist dogma while Michael Shermer contends that science, properly conceived, is a materialistic enterprise; for science to look beyond materialist explanations is to betray science and engage in superstition. Issues discussed include: materialism and its role in science, whether belief in God is compatible with a scientific perspective, and parapsychology. Michael Shermer is Editor-in-Chief of "Skeptic "magazine and the author of numerous books including "Skeptic."Rupert Sheldrake is a biologist and author of ten books including his most recent, "Science Set Free," which challenges scientific dogma.

For thousands of years, the faithful have honed proselytising strategies and talked people into believing the truth of one holy book or another. Indeed, the faithful often view converting others as an obligation of their faith -- and are trained from an early age to spread their unique brand of religion. The result is a world broken in large part by unquestioned faith. As an urgently needed counter to this tried-and-true tradition of religious evangelism, A Manual for Creating Atheists offers the first-ever guide not for talking people into faith -- but for talking them out of it. Peter Boghossian draws on the tools he has developed and used for more than twenty years as a philosopher and educator to teach how to engage the faithful in conversations that will help them value reason and rationality, cast doubt on their religious beliefs, mistrust their faith, abandon superstition, and irrationality, and ultimately embrace reason.

A scientific exploration into humanity's obsession with the afterlife and the quest for immortality from the bestselling author and sceptic Michael Shermer In his most ambitious work yet, Shermer sets out to discover what drives humans' belief in life after death. For millennia, the awareness of our own mortality and failings has led to religions concocting comforting notions of an afterlife, of heaven and hell, utopias and dystopias, and of the perfectibility of human nature. Heavens on Earth explores the numerous manifestations of the afterlife - a place where souls might go after the death of the physical body. Religious leaders have toiled to make sense of this place that a surprisingly high percentage of people believe exists, but from which no one has ever returned to report what it is really like. This is one of the most profound questions of the human condition and has long driven philosophers and theologians to try to understand the meaning and purpose of life for mortal beings, and how we can transcend mortality. Shermer details recent scientific attempts to achieve immortality by radical life extentionists, extropians, transhumanists, cryonicists and mind-uploaders, along with utopians who have attempted to create heaven on earth. Heavens on Earth concludes with an uplifting paean to purpose and progress and what we can do in the here-and-now, whether or not there is a hereafter.
