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.

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.

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.

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.

A new edition covering the latest scientific research on how the brain makes us believers or skeptics

Recent polls report that 96 percent of Americans believe in God, and 73 percent believe that angels regularly visit Earth. Why is this? Why, despite the rise of science, technology, and secular education, are people turning to religion in greater numbers than ever before? Why do people believe in God at all?

These provocative questions lie at the heart of How We Believe , an illuminating study of God, faith, and religion. Bestselling author Michael Shermer offers fresh and often startling insights into age-old questions, including how and why humans put their faith in a higher power, even in the face of scientific skepticism. Shermer has updated the book to explore the latest research and theories of psychiatrists, neuroscientists, epidemiologists, and philosophers, as well as the role of faith in our increasingly diverse modern world.

Whether believers or nonbelievers, we are all driven by the need to understand the universe and our place in it. How We Believe is a brilliant scientific tour of this ancient and mysterious desire.

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 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.

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.

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.

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.

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.

"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.

Virtually unknown today, Alfred Russel Wallace was the co-discoverer of natural selection with Charles Darwin and an eminent scientist who stood out among his Victorian peers as a man of formidable mind and equally outsized personality. Now Michael Shermer rescues Wallace from the shadow of Darwin in this landmark biography. Here we see Wallace as perhaps the greatest naturalist of his age--spending years in remote jungles, collecting astounding quantities of specimens, writing thoughtfully and with bemused detachment at his reception in places where no white man had ever gone. Here, too, is his supple and forceful intelligence at work, grappling with such arcane problems as the bright coloration of caterpillars, or shaping his 1858 paper on natural selection that prompted Darwin to publish (with Wallace) the first paper outlining the theory of evolution. Shermer also shows that Wallace's self-trained intellect, while powerful, also embraced surprisingly naive ideas, such as his deep interest in the study of spiritual manifestations and seances. Shermer shows that the same iconoclastic outlook that led him to overturn scientific orthodoxy as he worked in relative isolation also led him to embrace irrational beliefs, and thus tarnish his reputation. As author of Why People Believe Weird Things and founding publisher of Skeptic magazine, Shermer is an authority on why people embrace the irrational. Now he turns his keen judgment and incisive analysis to Wallace's life and his contradictory beliefs, restoring a leading figure in the rise of modern science to his rightful place.

" A] captivating raconteur of all the greatest hits of behavioral, evolutionary and neuropsychology . . . Fascinating."--"Los Angeles Times Book Review"

How did we make the leap from ancient hunter-gatherers to modern consumers, and why do people get so emotional about financial decisions? The national bestseller "The Mind of the Market" uncovers the evolutionary roots of our economic behavior.

Drawing on the new field of neuroeconomics, psychologist Michael Shermer investigates what brain scans reveal about bargaining, snap purchases, and establishing trust in business. He scrutinizes experiments in behavioral economics to understand why people hang on to losing stocks and why negotiations disintegrate into tit-for-tat disputes. He brings together findings from psychology and biology to describe how our tribal ancestry makes us suckers for brands, why researchers believe cooperation feels (biochemically) like sex, and how even capuchin monkeys get indignant if they don't get a fair reward for their work.

Entertaining and eye-opening, "The Mind of the Market" explains the real science of economics.

"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.
