Don’t Believe Everything You Think

Reg. $19. NOW $14.25

This enlightening book discusses how to recognize faulty thinking and develop the necessary skills to become a more effective problem solver. Author Thomas Kida identifies the 6 basic mistakes we make in thinking that leads many of us unconsciously to accept false ideas:

  1. We prefer stories to statistics.
  2. We seek to confirm, not to question, our ideas.
  3. We rarely appreciate the role of chance and coincidence in shaping events.
  4. We sometimes misperceive the world around us.
  5. We tend to oversimplify our thinking.
  6. Our memories are often inaccurate.

Kida vividly illustrates these tendencies with numerous examples that demonstrate how easily we can be fooled into believing something that isn’t true.

The Moral Arc (cover)

Reg. $16.99. NOW $11.89

The Moral Arc: How Science Makes Us Better People

In his book about moral progress, Dr. Michael Shermer demonstrates through extensive data and heroic stories that, thanks to science and reason, the arc of the moral universe bends toward truth, justice, and freedom. The Scientific Revolution was so world-changing that thinkers in other fields consciously aimed at revolutionizing the social, political, and economic worlds using the same methods of science. This led to the Age of Reason and the Enlightenment, which in turn created the modern secular world of liberal democracies, civil rights and civil liberties, equal justice under the law, open political and economic borders, and the expansion of the moral sphere to include more people—and now even animals—as worthy of moral consideration. Epic in scope, The Moral Arc is the Cosmos of human history.

Steven Pinker, author of The Better Angels of Our Nature, calls The Moral Arc “A thrilling and fascinating book, which could change your view of human history and human destiny.” Richard Dawkins, author of The God Delusion, says “The Moral Arc displays the impressive depth of Michael Shermer’s scholarship, wisdom and empathetic humanity, and it climaxes in a visionary flight of futuristic optimism. A memorable book, a book to recommend and discuss late into the night.”

Ankylosaur Attack! (cover)

Reg. $16.95. NOW $12.71

Ankylosaur Attack!

This mind-blowing feast for the eye depicts photorealistic CGI dinosaurs in their natural environment. A young ankylosaur (a plant-eating, heavy-plated dinosaur) living along the lush banks of a lake encounters an old ankylosaur. Gently, he endeavors to make contact, only to be rebuffed. Then a T. rex attacks, and old dinosaur is in grave danger. Will the T. rex triumph? It looks that way, until the young ankylosaur comes to the rescue, tail club swinging. This is book one in the Tales of Prehistoric Life series. Dramatic stories + eye-popping visuals = a surefire hit with young dinosaur lovers.

“Even by current high standards, the full-spread art is uncommonly photorealistic.” —Kirkus Reviews

Awards for the book

  • WINNER: Best Books for Kids & Teens, Canadian Children’s Book Centre (2012)

Pterosaur Trouble (cover)

Reg. $16.95. NOW $12.71

Pterosaur Trouble

In this science-informed followup to Ankylosaur Attack, Daniel Loxton tells a dramatic paleofiction tale of perhaps the largest flying animal ever to exist—the mighty pterosaur Quetzalcoatlus. While stalking a riverside for breakfast, the giraffe-sized pterosaur finds himself on the menu for a pack of small but ravenous feathered Velociraptor-like dinosaurs called Saurornitholestes. Can the giant escape from his Lilliputian assailants? Inspired by real-world fossil discoveries, this photorealistic adventure will delight and astonish. This is book two in the Tales of Prehistoric Life series.

“[A] riveting picture book…visually stunning…intriguing and original…an imaginative, scientifically based gem…”

Plesiosaur Peril (cover)

Reg. $16.95. NOW $12.71

Plesiosaur Peril

A group of plesiosaurs—ocean-dwelling cousins of the dinosaurs—keeps safe by swimming in a family pod. But then a baby plesiosaur swims too far from its mother, attracting the attention of something very large and hungry. The struggle for survival is on! A unique blend of digital artwork and landscape photography illustrates this thrilling encounter. This is the third and final book in the Tales of Prehistoric Life series, and a Finalist for the Lane Anderson Award for Best Science Book for Young Readers in 2014.

“It is apparent from the accurate appearance of the plesiosaurs that they were thoroughly researched. …the same is true for other prehistoric creatures… ichthyosaurs, ammonites, belemnites…. They are the best I’ve seen in any book of this kind. …this is a lovely and visually striking book that makes the perfect bedtime story for any child…”

Evolution: How We and All Living Things Came to Be (cover)

Reg. $18.95. NOW $14.21

Evolution: How We and All Living Things Came to Be

Can something as complex and wondrous as the natural world be explained by a simple theory? The answer is yes, and now Evolution explains how in a way that makes it easy to understand. Based on the acclaimed articles from Junior Skeptic (Skeptic magazine’s science magazine for kids), and combining lavish illustrations, breezy prose, and deep science, this spectacularly illustrated introduction to the theory of evolution (written for ages 8–13) takes us from Charles Darwin to modern-day science. Along the way, Evolution answers common questions (and clears up misunderstandings) that sometimes confuse people about the history of life on Earth. This book has been applauded by expert reviewers including the National Science Teachers Association, the American Association for the Advancement of Science, and the National Center for Science Education.

For donations of $500 or more, you are invited to join Michael Shermer at an epic Star Party at the historic Mt. Wilson Observatory where Edwin Hubble discovered the expanding universe (situated in the San Gabriel Mountains overlooking Los Angeles). We will meet for dinner at a place to be determined and then drive up Angeles Crest Highway to Mt. Wilson where we will tour the observatory grounds and spend as many hours as we like looking through one of the giant telescopes that Hubble used, and enjoy the company of fellow skeptics and science lovers. Date to be determined, likely to be in the March–May 2017 time frame for optimal weather and viewing. For reservations call our office at 1-626-794-3119. Good cause, good fun. Join us!

The Top 10 Myths of Terrorism

As usual, each year, we give away an informative booklet to thank you for your generous donations. This year, our free booklet examines whether terrorism is an “existential threat” to our way of life or even to our survival.

The Rise of the Use of the Term “Existential Threat”

Top 10 Myths of Terrorism (page 1 of free booklet)

Is terrorism really an “existential threat” to our way of life? Tracking the phrase with a Google Ngram search shows that it didn’t come into use until the late 1950s, most likely for describing the growing threat of global thermonuclear war. It crawls along the bottom of the curve through the 1960s, 1970s, and early 1980s. Then, around 1983, its use takes off in a steady upward trend line to 2001, after which it spikes dramatically upward in a hockey-stick like increase, clearly in response to 9/11. If ISIS or any of the other terrorist organizations grounded in Islamism were successful in their global jihad to bring about Sharia law, terrorism could become an existential threat. But will they succeed? No. Here are 10 myths about terrorism that explain why. Feel free to download, print and share this 4-page booklet.
