Foreigners could be forgiven for thinking that America is fast becoming a theocracy. No fewer than three of the remaining Republican candidates (Rick Perry, Rick Santorum, and Michele Bachmann) have declared that they were called by God to run for the country’s highest office. Congress recently voted to renew the country’s motto of “In God We Trust” on nothing less than the coin of the realm. And this year’s Thanksgiving Forum in Iowa (co-sponsored by the National Organization for Marriage) featured most of the major Presidential candidates competing for the title of God’s quarterback.

Rick Santorum, for example, in the course of denouncing Islamic Sharia law, inadvertently endorsed the same as long as it is a Christian on the Judge’s bench: “Unlike Islam, where the higher law and the civil law are the same, in our case, we have civil laws. But our civil laws have to comport with the higher law.” Not content to speak in such circular generalities, Santorum targeted his faith: “As long as abortion is legal—at least according to the Supreme Court—legal in this country, we will never have rest, because that law does not comport with God’s law.” God’s law? That is precisely the argument made by Islamic imams. But Santorum was only getting started. “Gay marriage is wrong. The idea that the only things that the states are prevented from doing are only things specifically established in the Constitution is wrong. … As a president, I will get involved, because the states do not have the right to undermine the basic, fundamental values that hold this country together.” Christian values only, of course.

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…)

On November 4, the Los Angeles Times published my Opinion Editorial entitled “What’s God Got to do With it?” (which I also posted on Skepticblog) about Congress reaffirming our national motto “In God We Trust.” I argued that trust does not come from God but from very specific social, political, and economic institutions.

Chuck Colson, the one-time special counsel for President Richard Nixon, one of the Watergate Seven who also pleaded guilty to obstruction of justice in his attempt to defame the Pentagon Papers defendant Daniel Ellsberg, and the man who found God and Jesus just in time for his jail sentence in federal prison, now blogs on political and social issues from a Christian perspective and has attempted a smack-down of my Op-Ed by arguing that “God Has a Lot to Do With It.”

His argument is summarized in his own words thusly: (continue reading…)

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…)

On Sunday morning, October 16, 2011, I taxied down to the Occupy Wall Street shindig from the 92nd Street Y where the Singularity Summit was unraveling as organizers scrambled to figure out how to work the wireless Internet system in the room while speakers boasted about how close we are to computers achieving human level intelligence. Human ignorance maybe, but intelligence? More on that topic later. (See my Scientific American column for January—out mid December—for my skeptical thoughts on when I think computers will achieve human level intelligence. Hint: We’re five years away…and always will be. But since I don’t want to sound so pessimistic, I have taken a cue from the singer/songwriters Zager and Evans, that the exordium and terminus of the singularity will be 2525 and 9595.)

When I posted some pics I snapped with my iPhone on twitter and made a couple of snide remarks, many of my fellow skeptics chided me for my insensitivity or berated me for my libertarian blindness to real social injustices being protested at the various “Occupy X” events. I call them events (or “shindigs”) because my general impression is that although there are some real issues being mentioned here and there in a desultory manner, for the most part I think most people I saw were in one of two categories: (1) onlookers such as myself snapping pictures and taking in the scene; (2) participants wanting to be part of what might turn out to be this generation’s (a) Woodstock or (b) Montgomery bus boycott. In my opinion it is neither, but I have to admit that I haven’t inhaled that much second-hand pot smoke since I was in college (yes, even at the staunchly conservative Pepperdine University, there were bountiful plumes of pot smoke wafting down the dorm room hallways!).

I have appended various photographs at the end of this essay to let the moment speak for itself, grammatically challenged signs and all, but let me first make a few comments regarding what might be gleaned from the party atmosphere of a few salient points of political and economic significance.

Estimating the number of people who have
experienced the paranormal or supernatural

The Drake Equation is the famous formula developed by the astronomer Frank Drake for estimating the number of extraterrestrial civilizations:

N = R × f_p × n_e × f_l × f_i × f_c × L where…

• N = the number of communicative civilizations,
• R = the rate of formation of suitable stars,
• f_p = the fraction of those stars with planets,
• n_e = the number of earth-like planets per solar system,
• f_l = the fraction of planets with life,
• f_i = the fraction of planets with intelligent life,
• f_c = the fraction of planets with communicating technology, and
• L = the lifetime of communicating civilizations.

The equation is so ubiquitous that it has even been employed in the popular television series The Big Bang Theory for computing the number of available sex partners within a 40-mile radius of Los Angeles (5,812). My favorite parody of it is by the cartoonist Randall Munroe as one in a series of his clever science send-ups, entitled “The Flake Equation” (on xkcd.com) for calculating the number of people who will mistakenly think they had an ET encounter.

This is a review of The Better Angels of Our Nature: Why Violence Has Declined, by Steven Pinker
(October 2011, Viking. 771 pages. ISBN 978-0-670-02295-3). Originally published in the Autumn issue of The American Scholar as “Getting Better All the Time.”

In The Man Who Shot Liberty Valance, John Ford’s classic 1962 film, a clash of moral codes unfolds in the wild-west frontier town of Shinbone, Arizona. I call these moral codes the Cowboy Code, where disputes are settled and justice is served between individuals who have taken the law into their own hands, and the Law Code, where disputes are settled and justice is served between all members of the society who, by virtue of living there, have tacitly agreed to obey the rules. The Cowboy Code is represented by John Wayne’s character, Tom Doniphon, a fiercely loyal and deeply honest gunslinger duty-bound to enforce 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 make the transition from cowboy justice to 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 that men settle their disputes between themselves. Despite Valance’s constant taunting 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 pack’n a handgun,” Stoddard rejoins, “I don’t want to kill him. I just want to put him in jail.” At long last, however, Stoddard decides to take Doniphon’s advice that “out here a man settles his own problems,” and turns to him for gun-fighting lessons. When Valance challenges Stoddard to a dual, the overconfident naïf accepts and a late-night showdown ensues. In a darkened street, the two men square off. Stoddard is trembling in fear 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 United States Senator.

In the 2010 documentary film, The Tillman Story, the story of Pat Tillman and his tragic death at the hands of “friendly fire” is retold. Tillman was the NFL star who gave it all up to join the military cause in Afghanistan after being inspired by 9/11 to do something for his country. He did not do it for the glory or publicity, and gave up a lucrative football career for what he perceived to be a worthy cause. After his death the U.S. government implemented a publicity campaign to use Tillman’s death as a tool to promote the war as a cause so worthy that even a highly-paid NFL star believed it to be worth the sacrifice. What the government failed to mention is that Tillman was killed at the hands of his fellow soldiers during a “fog of war” incident in a steep and narrow slot canyon in which there was much confusion about where enemy fire was originating. It’s a very disturbing film to watch—infuriating in fact—and Jon Krakauer’s book, Where Men Win Glory, presents the story in excruciating detail in a compelling narrative.

Pat Tillman was an atheist. At his funeral his younger brother Richard got up to speak, visibly upset, noticeably inebriated, and with beer in hand proceeded to thank everyone for their warm sentiments, but upbraided those like Maria Shriver and Senator John McCain who made religious overtones in their sentiments, noting about his brother Pat: “He’s not with God, he’s fucking dead. He’s not religious. Thanks for your thoughts, but he’s fucking dead.” (continue reading…)

This article first appeared as an alternative medicine opinion editorial for the American Medical Associations’s Virtual Mentor Journal, Volume 13, Number 6: 389–393, June 2011.

For many years now there has been considerable debate between so-called complementary and alternative medicine (CAM) and mainstream science-based medicine. In reality there is no debate because there is only science-based medicine and everything else that has yet to be tested. Most of CAM falls into this latter category. This does not automatically mean that all CAM claims are false; only that most of them have yet to be tested through the rigorous methods of science, which begins with the null hypothesis that holds that the hypothesis under investigation is not true (null) until proven otherwise. A null hypothesis states that X does not cause Y. If you think X does cause Y then the burden of proof is on you to provide convincing experimental data to reject the null hypothesis.

The statistical standards of proof needed to reject the null hypothesis are substantial. Ideally, in a controlled experiment, we would like to be at least 95–99 percent confident that the results were not due to chance before we offer our provisional assent that the effect may be real. Everyone is familiar with the process already through news stories about the FDA approving a new drug after extensive clinical trials. The trials to which they refer involve sophisticated methods to test the claim that Drug X (say a statin drug) improves outcomes in Disease Y (say cholesterol-related atherosclerosis). The null hypothesis states that statins do not lower cholesterol and thus have no effect on atherosclerosis. Rejecting the null hypothesis means that there was a statistically significant difference between the experimental group receiving the statins and the control group that did not.

In most cases CAM hypotheses do not pass these simple criteria. They have either failed to reject the null hypothesis, or they haven’t even been rigorously tested to know whether or not they could reject the null hypothesis. (continue reading…)
