Has there ever been a time when the political process has been so bipartisan and divisive? Yes, actually, one has only to recall the rancorousness of the Bush-Gore or Bush-Kerry campaigns, harken back to the acrimonious campaigns of Nixon or Johnson, read historical accounts of the political carnage of both pre- and post-Civil War elections, or watch HBO’s John Adams series to relive in full period costuming the bipartite bitterness between the parties of Adams and Jefferson to realize just how myopic is our perspective.

We can go back even further into our ancestral past to understand why the political process is so tribal. But for the business attire donned in the marbled halls of congress we are a scant few steps removed from the bands and tribes of our hunter-gatherer ancestors, and a few more leaps afield from the hominid ancestors roaming together in small bands on the African savannah. There, in those long-gone millennia, were formed the family ties and social bonds that enabled our survival among predators who were faster, stronger, and deadlier than us. Unwavering loyalty to your fellow tribesmen was a signal that they could count on you when needed. Undying friendship with those in your group meant that they would reciprocate when the chips were down. Within-group amity was insurance against the between-group enmity that characterized our ancestral past. As Ben Franklin admonished his fellow revolutionaries, we must all hang together or we will surely hang separately.

In this historical trajectory our group psychology evolved and along with it a propensity for xenophobia—in-group good, out-group bad. Thus it is that members of the other political party are not just wrong—they are evil and dangerous. Stray too far from the dogma of your own party and you risk being perceived as an outsider, an Other we may not be able to trust. Consistency in your beliefs is a signal to your fellow group members that you are not a wishy-washy, Namby Pamby, flip-flopper, and that I can count on you when needed. (continue reading…)

A review of Lisa Randall’s Knocking on Heaven’s Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World (Ecco, 2011).

Order the book from Amazon

LISA RANDALL HAS BEEN JUSTLY APPRAISED by Time magazine as one of the “100 most influential people in the world” for her work in theoretical particle physics. From her position at Harvard University, she often travels: to the European Laboratory for Particle Physics, CERN, in Switzerland, where her theories are being put to the test in the Large Hadron Collider (LHC); to speaking engagements with professional and public audiences about her work in particular and the awe and wonder of science in general; and to rock formations where her chalked fingers can find ways to defy gravity. On the side, she writes popular books, such as her acclaimed Warped Passages¹.

In Knocking on Heaven’s Door, Randall picks up the story from where she left off when the LHC was years away from first collision, expanding her horizon from, as she poetically puts it, “what’s so small to you is so large to me” to “what’s so large to you is so small to me.” In other words, the book ranges from the smallest known particles to the entire bubble universe, from 10⁻³⁵ meters (the Planck length, where quantum gravity rules) to 10²⁷ meters (the entire visible universe, 100 billion light-years across, where dark matter and dark energy dominate), a stunning 62 orders of magnitude. (Randall correctly notes the age of the universe at 13.75 billion years, clarifying her apparently paradoxical figure of 100 billion light-years thusly: “The reason the universe as a whole is bigger than the distance a signal could have traveled given its age is that space itself has expanded.” She unpacks that sentence in the book.)

He may be invoked in the national motto, but God has nothing to do with why Americans are free and secure

This op-ed was originally published in the Los Angeles Times, Friday November 4, 2011.

The House of Representatives voted last week by a margin of 396–9 to reaffirm as the national motto the phrase “In God We Trust,” and encouraged its pronouncement on public buildings and continued printing on the coin of the realm. The motto was made official in 1956 during the height of Cold War hysteria over godless communism and—in the words of Brig. Gen. Jack D. Ripper in Stanley Kubrick’s and Peter Sellers’ 1964 classic antiwar film Dr. Strangelove—“Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.”

As risible a reason as this was for knocking out a few bricks in the wall separating state and church, it was at least understandable in the context of the times. But today, with no communist threats and belief in God or a universal spirit among Americans still holding strong at about 90%, according to a 2011 Gallup Poll, what is the point of having this motto? The answer is in the wording of the resolution voted on: “Whereas if religion and morality are taken out of the marketplace of ideas, the very freedom on which the United States was founded cannot be secured.” (continue reading…)

TO ALL TEACHERS AND PROFESSORS who are teaching courses in skepticism, critical thinking, science and pseudoscience, science and the paranormal, science studies, history or philosophy of science, the psychology of paranormal beliefs, religious studies, and the like…

Please send us your course syllabuses, reading lists, video/YouTube links, classroom demonstration ideas, student projects and experiments, research project ideas, and the like to my graduate student Anondah Saide. I want to add them to my own course syllabus on Skepticism 101, and create an online Skeptical Studies Program at Skeptic.com for teachers and professors everywhere to go to in a creative commons/open source system so that we can build a new academic field going forward with skepticism into academia.

I know that such courses are being taught around the world because for the past two decades of publishing Skeptic magazine and writing skeptical books, I receive a lot of mail from teachers and professors seeking permission to use our materials.

What I would like to do is to create academic departments of Skeptical Studies, as the next step in the skeptical movement. (See, for example, Phil Zuckerman’s program of Secular Studies he is implementing this year at Pitzer College in Claremont, where I teach a graduate course in the spring. We have magazines and journals, trade books and conferences. The next step is a more organized penetration into academia via courses, textbooks, departments, and the like. I want to create a clearing house, an open-source site for people to access materials that will be made available to create your own course in Skeptical Studies, such as Skepticism 101: syllabuses, books, articles, assignments, videos, demonstrations, experiments, research projects, and the like. I am envisioning something along the lines of how psychology became an academic field a century ago.

To start the process off I share with you my own course syllabus for Skepticism 101, which I am teaching this semester starting this week at Chapman University on Tuesdays from 4–7pm with 36 freshman, the future of the skeptical movement!

Although you wouldn’t know it by watching the local news, humankind is becoming more civilized

This review of The Better Angels of Our Nature: Why Violence Has Declined by Steven Pinker (Penguin Books, 2012. ISBN 9780143122012) appeared in The American Scholar in August 2011.

In John Ford’s classic 1962 film, The Man Who Shot Liberty Valance, a clash of moral codes unfolds in the Wild West frontier town of Shinbone. Under the Cowboy Code, disputes are settled and justice is served between individuals who have taken the law into their own hands, and under the Law Code, disputes are settled and justice is served by institutions because most members of society have agreed to obey the rules. The Cowboy Code is represented by John Wayne’s character, Tom Doniphon, a gunslinger who enforces justice on his own terms through the power of his presence backed by the gun on his hip. The Law Code is embodied by Jimmy Stewart’s Ransom Stoddard, an attorney hell-bent on seeing his beloved Shinbone embrace the rule of law. Lee Marvin’s Liberty Valance is a coarse highwayman who respects only one man, Tom Doniphon, because they share the Cowboy Code. Despite Valance’s constant flouting of the law, Stoddard holds to his belief that until Valance is caught doing something illegal there can be no justice. When Doniphon tells Stoddard, “You better start packin’ a handgun,” Stoddard rejoins, “I don’t want to kill him. I just want to put him in jail.” At long last, however, Stoddard takes Doniphon’s advice that “out here a man settles his own problems” and turns to him for gunfighting lessons. When Valance challenges Stoddard to a duel, the overconfident naïf accepts and a late-night showdown ensues. In a darkened street, the two men square off. Stoddard trembles while Valance mocks and scorns him, shooting first too high and then too low. When Valance takes aim to kill, Stoddard shakily draws his weapon and discharges it. Valance collapses in a heap. Having felled one of the toughest guns in the West, Stoddard goes on to become a local hero, building that image into political capital and working his way up from local politics to a distinguished career as a U. S. senator.
