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.

The historically challenged Michele Bachmann minced no words when she declared: “I have a biblical worldview. And I think, going back to the Declaration of Independence, the fact that it’s God who created us—if He created us, He created government. And the government is on His shoulders, as the book of Isaiah says.” A Bachmann administration would apparently consult the Old Testament for moral guidance because, she pronounced with her usual hubris born of historical ignorance, “American exceptionalism is grounded on the Judeo-Christian ethic, which is really based upon the 10 Commandments. The 10 Commandments were the foundation for our law.” Really? Where in our laws does it prohibit belief in gods other than Yahweh, ban the manufacturing of graven images, forbid taking the Lord’s name in vain, bar us from working on the Sabbath, require us to honor our parents, and interdict the coveting of our neighbor’s house, wife, slave, servant, ox, and ass? Even the notoriously difficult to follow 7th commandment is not illegal, much to the relief of candidate Gingrich.

Surely the pluralism of America’s religious diversity is what makes us great. Not so, said Rick Perry: “In every person’s heart, in every person’s soul, there is a hole that can only be filled by the Lord Jesus Christ.” But don’t politicians owe allegiance to the Constitution? Alas, pace Perry, no. “Somebody’s values are going to decide what the Congress votes on or what the President of the United States is going to deal with. And the question is: Whose values? And let me tell you, it needs to be our values—values and virtues that this country was based upon in Judeo-Christian founding fathers.” You mean the values and virtues of the atheist Thomas Paine and the Deist Thomas Jefferson, the latter of whom rejected Jesus, the resurrection, and all miracles as nonsense on stilts, and yet who nonetheless insisted on building an impregnable wall protecting religion from the encroachment of state abuse?

Finally, the erudite Newt Gingrich was more specific in his plan to bring about a Christian nation through legal means, starting by redacting the 14th Amendment: “I am intrigued with something which Robby George at Princeton has come up with, which is an interpretation of the 14th Amendment, in which it says that Congress shall define personhood. That’s very clearly in the 14th Amendment. And part of what I would like to explore is whether or not you could get the Congress to pass a law which simply says: Personhood begins at conception. And therefore—and you could, in the same law, block the court and just say, ‘This will not be subject to review,’ which we have precedent for. You would therefore not have to have a Constitutional amendment, because the Congress would have exercised its authority under the 14th Amendment to define life, and to therefore undo all of Roe vs. Wade, for the entire country, in one legislative action.” If the 14th Amendment can be averted on a technicality, what about the others?

If you are a Christian, of course, this is the mother’s milk of nursing privilege. Power to the (Christian) people. It’s the oldest trope in history—religious tribalism—and it’s being played out in the land of liberty. So it is prudent for us to educe that other national motto found on the Seal of the United States first proffered by the founding patriarchs John Adams, Benjamin Franklin, and Thomas Jefferson and adopted by an Act of Congress in 1782: E Pluribus Unum—Out of many, one.

How many make up our one? There are 300 million Americans. Gallup, Pew, and other pollsters consistently find that about 10 percent of Americans do not believe in God. That’s 30 million Americans. That’s not all. A 2008 study by the American Religious Identification Survey (ARIS) revealed that between 1990 and 2008 the fastest growing religious group in America were the “Nones,” or people who responded “None, No religion, Humanistic, Ethical Culture, Agnostic, Atheist, or Secular” in the survey. Remarkably, this group gained more new members (19,838,000) than either Catholics (11,195,000) or Protestants (10,980,000), and totals 15 percent, or 45 million Americans.

Read that number again candidates! If you are elected President of these United States are you really going to dismiss and openly refuse to represent 45 million people living under the same Constitution as you? And that’s just the Nones. Tens of millions more Jews, Mormons, Muslims, Buddhists, Hindus, Baha’i, Jains, Taoists, Wiccans, New Agers, and other law-abiding loyal Americans—many serving in the armed services protecting our liberty—are non-Christians who hold the same dreams and aspirations for what this country has to offer as do Christians. In fact, at most Christians comprise 60–76 percent of all Americans, which means that somewhere between 72 million and 120 million U.S. citizens are non-Christians no less deserving of representation in this democracy.

It’s time for candidates and politicians to stop the God talk and start acting like true representatives of the people—all of the people. It’s time for the 45 million Nones to demand both respect and representation no less than any other American, and for presidential candidates, when asked about their religion, to reply something along these lines:

I understand why you are curious about my religious beliefs, but I am not running to represent only Americans who happen to believe what I believe about God and religion. I am running to represent Americans of all faiths, and even the tens of millions of Americans who have no religion. If elected, my allegiance is to the Constitution and my duty is to uphold the laws of this great land, which are to be applied equally and without prejudice to all Americans no matter their color or creed. I realize that some candidates and politicians pander to their religious voting block in hopes of gaining support by tapping ancient tribal prejudices, but that is not my way. I get why other candidates are tempted to appeal to those deep emotions that are stirred by religious unity against those who believe differently, but I am trying to do something different. If elected I fully intend to represent all Americans under my jurisdiction, not just those Americans whose beliefs I happen to share. I am trying to build a better America for all Americans, not some. The original motto of this country is E Pluribus Unum. It means “Out of many, one.” It means that we are stronger together than separate, united by our common belief in liberty and the freedom to believe whatever you want as long as it doesn’t harm others. As a candidate for the highest office of this noble nation my faith is in its people—all of the people—and what we are able to do together to make the world a better place to live.

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.

This is why, for example, the political beliefs of members of each party are so easy to predict. Without even knowing you, I predict that if you are a liberal you read the New York Times, listen to NPR radio, watch CNN, hate George W. Bush and loathe Sarah Palin, are pro-choice, anti-gun, adhere to the separation of church and state, are in favor of universal healthcare, vote for measures to redistribute wealth and tax the rich in order to level the playing field, and believe that global warming is real, human caused, and potentially disastrous for civilization if the government doesn’t do something dramatic and soon. By contrast, I predict that if you are a conservative you read the Wall Street Journal, listen to conservative talk radio, watch Fox News, love George W. Bush and venerate Sarah Palin, are pro-life, anti-gun control, believe that America is a Christian nation that should meld church and state, are against universal healthcare, vote against measures to redistribute wealth and tax the rich, and are skeptical of global warming and/or government schemes to dramatically alter our economy in order to save civilization.

Research in cognitive psychology shows, for example, that once we commit to a belief we employ the confirmation bias, in which we look for and find confirming evidence in support of it and ignore or rationalize away any disconfirming evidence. In one experiment subjects were presented with evidence that contradicted a belief they held deeply, and with evidence that supported those same beliefs. The results showed that the subjects recognized the validity of the confirming evidence but were skeptical of the value of the disconfirming evidence. The confirmation bias was poignantly on display during the run-up to the 2004 Bush-Kerry Presidential election when subjects had their brains scanned while assessing statements by both Bush and Kerry in which the candidates clearly contradicted themselves. Half of the subjects were self-identified as “strong” Republicans and half “strong” Democrats. Not surprisingly, in their assessments Republican subjects were as critical of Kerry as Democratic subjects were of Bush, yet both let their own preferred candidate off the evaluative hook. The brain scans showed that the part of the brain most associated with reasoning—the dorsolateral prefrontal cortex—was quiet. Most active were the orbital frontal cortex that is involved in the processing of emotions, the anterior cingulate that is associated with conflict resolution, and the ventral striatum that is related to rewards.

In other words, reasoning with facts about the issues is quite secondary to the emotional power of first siding with your party and then employing your reason, intelligence, and education in the service of your political commitment.

Our political parties today evolved out of the Paleolithic parties of the past.

WAS PRESIDENT BARACK OBAMA BORN IN HAWAII? I find the question so absurd, not to mention possibly racist in its motivation, that when I am confronted with “birthers” who believe otherwise, I find it diffcult to even focus on their arguments about the difference between a birth certificate and a certificate of live birth. The reason is because once I formed an opinion on the subject, it became a belief, subject to a host of cognitive biases to ensure its verisimilitude. Am I being irrational? Possibly. In fact, this is how most belief systems work for most of us most of the time.

We form our beliefs for a variety of subjective, emotional and psychological reasons in the context of environments created by family, friends, colleagues, culture and society at large. After forming our beliefs, we then defend, justify and rationalize them with a host of intellectual reasons, cogent arguments and rational explanations. Beliefs come first; explanations for beliefs follow. In my new book The Believing Brain (Holt, 2011), I call this process, wherein our perceptions about reality are dependent on the beliefs that we hold about it, belief-dependent realism. Reality exists independent of human minds, but our understanding of it depends on the beliefs we hold at any given time.

I patterned belief-dependent realism after model-dependent realism, presented by physicists Stephen Hawking and Leonard Mlodinow in their book The Grand Design (Bantam Books, 2011). There they argue that because no one model is adequate to explain reality, “one cannot be said to be more real than the other.” When these models are coupled to theories, they form entire worldviews.

Once we form beliefs and make commitments to them, we maintain and reinforce them through a number of powerful cognitive biases that distort our percepts to fit belief concepts. Among them are:

ANCHORING BIAS: relying too heavily on one reference anchor or piece of information when making decisions.

AUTHORITY BIAS: valuing the opinions of an authority, especially in the evaluation of something we know little about.

BELIEF BIAS: evaluating the strength of an argument based on the believability of its conclusion.

CONFIRMATION BIAS: seeking and finding confirming evidence in support of already existing beliefs and ignoring or reinterpreting disconfirming evidence.

On top of all these biases, there is the in-group bias, in which we place more value on the beliefs of those whom we perceive to be fellow members of our group and less on the beliefs of those from different groups. This is a result of our evolved tribal brains that lead us not only to place such value judgment on beliefs but also to demonize and dismiss them as nonsense or evil, or both.

Belief-dependent realism is driven even deeper by a meta bias called the bias blind spot, or the tendency to recognize the power of cognitive biases in other people but to be blind to their influence on our own beliefs. Even scientists are not immune, subject to experimenter-expectation bias, or the tendency for observers to notice, select and publish data that agree with their expectations for the outcome of an experiment and to ignore, discard or disbelieve data that do not.

This dependency on belief and its host of psychological biases is why, in science, we have built-in self-correcting machinery. Strict double-blind controls are required, in which neither the subjects nor the experimenters know the conditions during data collection. Collaboration with colleagues is vital. Results are vetted at conferences and in peer-reviewed journals. Research is replicated in other laboratories. Disconfirming evidence and contradictory interpretations of data are included in the analysis. If you don’t seek data and arguments against your theory, someone else will, usually with great glee and in a public forum. This is why skepticism is a sine qua non of science, the only escape we have from the belief-dependent realism trap created by our believing brains.

According to a 2009 Harris Poll of 2,303 adult Americans, when people are asked to “Please indicate for each one if you believe in it, or not,” the following results were revealing:¹

• 82% believe in God
• 76% believe in miracles
• 75% believe in Heaven
• 73% believe in Jesus is God
  or the Son of God
• 72% believe in angels
• 71% believe in survival
  of the soul after death
• 70% believe in the
  resurrection of Jesus Christ
• 61% believe in hell
• 61% believe in
  the virgin birth (of Jesus)
• 60% believe in the devil
• 45% believe in Darwin’s
  Theory of Evolution
• 42% believe in ghosts
• 40% believe in creationism
• 32% believe in UFOs
• 26% believe in astrology
• 23% believe in witches
• 20% believe in reincarnation

Wow. More people believe in angels and the devil than believe in the theory of evolution. That’s disturbing. And yet, such results should not surprise us as they match similar survey findings for belief in the paranormal conducted over the past several decades.² And it is not just Americans. The percentages of Canadians and Britons who hold such beliefs are nearly identical to those of Americans.³ For example, a 2006 Readers Digest survey of 1,006 adult Britons reported that 43 percent said that they can read other people’s thoughts or have their thoughts read, more than half said that they have had a dream or premonition of an event that then occurred, more than two-thirds said they could feel when someone was looking at them, 26 percent said they had sensed when a loved-one was ill or in trouble, and 62 percent said that they could tell who was calling before they picked up the phone. In addition, a fifth said they had seen a ghost and nearly a third said they believe that Near-Death Experiences are evidence for an afterlife.⁴

Although the specific percentages of belief in the supernatural and the paranormal across countries and decades varies slightly, the numbers remain fairly consistent that the majority of people hold some form of paranormal or supernatural belief.⁵ Alarmed by such figures, and concerned about the dismal state of science education and its role in fostering belief in the paranormal, the National Science Foundation (NSF) conducted its own extensive survey of beliefs in both the paranormal and pseudoscience, concluding with a plausible culprit in the creation of such beliefs:

Belief in pseudoscience, including astrology, extrasensory perception (ESP), and alien abductions, is relatively widespread and growing. For example, in response to the 2001 NSF survey, a sizable minority (41 percent) of the public said that astrology was at least somewhat scientific, and a solid majority (60 percent) agreed with the statement “some people possess psychic powers or ESP.” Gallup polls show substantial gains in almost every category of pseudoscience during the past decade. Such beliefs may sometimes be fueled by the media’s miscommunication of science and the scientific process.⁶

I too would like to lay the blame at the feet of the media, or science education in general, because the fix then seems straightforward—just improve how we communicate and educate science. But that’s too easy. In any case, the NSF’s own data do not support it. Although belief in ESP decreased from 65% among high school graduates to 60% among college graduates, and belief in magnetic therapy dropped from 71% among high school graduates to 55% among college graduates, that still leaves over half of educated people fully endorsing such claims! And for embracing alternative medicine, the percentages actually increased, from 89% for high school grads to 92% for college grads.

Perhaps a deeper cause may be found in another statistic: 70% of Americans still do not understand the scientific process, defined in the NSF study as grasping probability, the experimental method, and hypothesis testing. So one solution here is teaching how science works in addition to the rote memorization of scientific facts. A 2002 article in Skeptic magazine entitled “Science Education is No Guarantee of Skepticism,” presented the results of a study that found no correlation between science knowledge (facts about the world) and paranormal beliefs. The authors, W. Richard Walker, Steven J. Hoekstra, and Rodney J. Vogl, concluded: “Students that scored well on these [science knowledge] tests were no more or less skeptical of pseudoscientific claims than students that scored very poorly. Apparently, the students were not able to apply their scientific knowledge to evaluate these pseudoscientific claims. We suggest that this inability stems in part from the way that science is traditionally presented to students: Students are taught what to think but not how to think.”⁷ The scientific method is a teachable concept, as evidenced in the NSF study that found that 53% of Americans with a high level of science education (nine or more high school and college science/math courses) understand the scientific process, compared to 38% with a middle level (six to eight such courses) of science education, and 17% with a low level (less than five such courses) of science education. So maybe the key to attenuating superstition and belief in the supernatural is in teaching how science works, not just what science has discovered. I have believed this myself for my entire career in science and education. If I didn’t believe it I might not have gone into the business of teaching, writing, and editing science in the first place.

Alas, I have come to the conclusion that belief is largely immune to attack by direct educational tools, at least for those who are not ready to hear it. Belief change comes from a combination of personal psychological readiness and a deeper social and cultural shift in the underlying zeitgeist of the times, which is affected in part by education, but is more the product of larger and harder-to-define political, economic, religious, and social changes.

On Saturday, February 5, 2011, my audio book producer John Wagner and I took a break from endless hours of my reading aloud (with John editing out my countless mistakes) my next book, The Believing Brain, which ironically includes chapters on UFOs, aliens, and conspiracy theories. Ironic because for this break John and I took what we thought would be an uneventful tour of the beautiful new National Museum of Nuclear Science and History in Albuquerque, New Mexico.

This is definitely a museum well worth visiting for a comprehensive tour of all things atomic. It was originally opened in 1969 as the Sandia Atomic Museum, but then changed in 1973 to the National Atomic Museum to include a broader history of the peaceful use of nuclear energy, and finally morphed into the new building that now houses the collection, which includes replicas of the Fat Man and Little Boy bombs (see photograph), along with a B-29, a B-52, an F-105, an A-7, an Atomic Cannon, a Titan II Rocket, a Minuteman Missile, a Jupiter Missile, a Thor Missile, and hundreds more smaller items inside the museum building itself, including these two amusing early uses of atomic energy for “health” purposes:

1. The Spectro-Chrome Device, “invented around 1911, was used in the practice of Spectro-Chrome therapy. The inventors believed that every element exhibits a certain color. Ninety-seven percent of a human body is made up of four main elements: oxygen, hydrogen, nitrogen and carbon. The color waves of these elements were thought to be blue, red, green, and yellow respectively. Illness was thought to occur when one or more of these colors became out of balance, either too dim or too brilliant. The Spectro-Chrome Device treated the afflicted part of the body with the proper amount of color and light to restore balance in the body. Once balance occurred, the patient should recover.” The operative word here is “should”.

2. The Revigator: “This large pottery crock was lined with Radium ore. Instructions on the jar suggest that you fill it every night with water and drink an average of six or more glasses daily. After its discovery by Pierre and Marie Curie in 1898, Radium was considered a ‘cure-all’ until the early 1920s.” The operative word here is “crock”.

We were also quite impressed with the array of nuclear-tipped missiles, including these two (see below), one of which had been in space and survived the reentry. Can you tell which one?

Then something really weird happened. As John and I were strolling along the exhibits talking about this and that, I wondered out loud if they had any examples of the sand that was turned into glass in the Trinity atomic bomb test explosion on July 16, 1945 at White Sands, New Mexico. Just then the museum docent who had kindly joined us to offer more detailed narratives to accompany the printed plaques, explained that they did, indeed, have a display of said sand-to-glass fusion, and there it was, beautiful in its horrific creation. We chatted it up with the docent for a time, at which point I asked if it is possible to go to White Sands and see the glass in situ. She said, “no, it has all been taken away.” I said, “who took it away, and where is it?” She responded rhetorically: “Right, who took it, where, and why?” I repeated the question and she repeated the rhetorical answer.

“Uh, what are you saying? Someone secreted it away?” “Yes, right, it’s gone and no one knows where,” she explained unhelpfully. “But someone must know,” I pleaded.

At this point she hinted that there are many government secrets still surrounding nuclear weapons. Of this I am quite certain, since governments do keep secrets in the interests of national security, but she seemed to be speaking of a different sort of secret. I probed for more examples of such secrets. “When you go outside,” she offered, “you will see a B-29 bomber, like the one that dropped the bombs on Hiroshima and Nagasaki. Look at the serial number on the tail. It says 451748. But if you go inside the cockpit and look behind the pilot seat you will find another serial number for that plane: 451749.”

“Okay, so someone messed up,” I suggested. “After all, the people who spray paint numbers on planes are probably not the engineers who design and build planes for Boeing. So what?”

“Well, I looked into that matter myself when I was restoring the plane,” she continued breathlessly, “and it turns out that plane number 451749 disappeared over the South China Sea in a mysterious explosion in the early 1950s. Supposedly one of the bombs armed itself inside the B-29 and then detonated itself.”

“Is that possible?” I queried, wondering just where this story was going but suspecting it was about to take a dramatic turn into conspiratorial waters.

“Have you ever heard of a bomb arming itself and then detonating itself?” she queried. I had to admit that I hadn’t, but I also signaled to her that I didn’t know much at all about bombs and what they are capable of doing, but then suggested that I could certainly imagine how the same people who spray paint the wrong serial number on the tail of a plane could easily screw up while arming a bomb and cause it to explode. Human error happens not infrequently in operating complex machinery.

“Well, I’ll tell you—that doesn’t happen,” she countered my feeble objections. “That plane was shot down or intentionally destroyed.” Okay, shot down. Intentionally destroyed. By whom, enemy fighter planes or an anti-aircraft missile over enemy territory? “No, it was destroyed by our own government.” Why? “Because the crew saw something.” What? What did they see? “Remember, this was not long after Roswell….”

Okay, here we go, we’re on my turf now! Aliens, UFOs, Roswell, New Mexico. The alien encounter in 1947. The crew, she said, probably had a UFO encounter of some sort, and they were silenced. “Wow, that’s incredible,” I enthused. “How can I look into this further?” At this point my erstwhile conspiratorialist grew quiet, warning me in a voice too fervent by half: “You can try but I wouldn’t get my hopes up. I made some calls myself and finally got a hold of a two-star general, who told me ‘I don’t know what happened and you don’t either.’”

“What did you take that to mean?,” I pushed. “He was telling me that if I didn’t drop my investigation of what really happened to plane number 451749, that Men-In-Black would come pay me a visit,” she explained unhesitatingly and with enough dramatis that I would get the message myself.

So…there it is. That’s all I know from my brief visit and having conducted no further investigations. If anyone reading this knows, or knows someone who knows…or who has a Friend-of-a-Friend who knows someone who knows what happened to B-29 plane number 451749, I would really like to know myself. And if there are any M.I.B. out there planning to come visit me, bring an extra pair of those cool black sunglasses for me.

I believe in the Principle of Freedom: All people are free to think, believe, and act as they choose, so long as they do not infringe on the equal freedom of others.

I believe in civil liberties, civil rights, and the freedoms guaranteed in the United States Constitution, including and especially freedom of speech, freedom of association, freedom to assemble peacefully, freedom to petition grievances, freedom to worship (or not), freedom of the press, freedom of reproductive choice, freedom to bear arms, etc.

I believe in the sanctity of private property, the rule of law, and equal treatment under the law.

I believe in free will, free choice, moral culpability, and personal responsibility.

I believe in truth seeking and truth telling.

I believe in trust and trustworthiness.

I believe in fairness and reciprocity.

I believe in love, marriage, and fidelity.

I believe in family, friendship, and community.

I believe in honor, loyalty, and commitment to family, friends, and community members.

I believe in forgiveness when it is genuinely asked for or offered.

I believe in kindness, generosity, and charity, especially voluntary aid to others in need.

I believe in science as the best method ever devised for understanding how the world works.

I believe in reason and logic and rationality as cognitive tools for answering questions, solving problems, and devising solutions to life’s many problems and quandaries.

I believe in technological growth, cultural advancement, and moral progress.

I believe in the almost illimitable capacity of human creativity and inventiveness for our species to flourish into the far future on this planet and others.

Ad astra per aspera!

So, if you are ever asked by a believer what you believe in, offer your own list along these lines of values that you honor, and then ask, “Why, what do you believe in? Do you not honor these values?”

The impetus for essay, which I penned on a plane to Los Angeles on October 15, 2010, was that I was asked this very question the night before during the Q&A after a talk I delivered before a sizable audience at the University of Minnesota in Minneapolis, sponsored by CASH (Campus Atheists, Skeptics, and Humanists), supported by several other Minnesota atheist and humanist groups, and attended as well by many believers. The woman who made the inquiry explained that as an atheist she is often asked this question in a tone implying that atheists cannot or do not believe in anything.

Nothing could be further from the truth, of course, but such is the delimiting effect of religious belief and the myth that without God anything goes. Quite the contrary. Without God, values matter more here and now than they ever could in any projected afterlife proscenium where the moral play is finally enacted.

P.S. The final line above translates as: To the stars with difficulty. The phrase originated with the Roman poet Seneca the Younger and was made famous on a plaque honoring the Apollo 1 astronauts who perished in a fire on the launch pad at Cape Canaveral.

My keynote talk was Why People Believe Weird Things, a shortened version of which you can see on Ted.com, where I originally delivered this lecture. It includes much discussion about how east it is to fool the brain, perceptual illusions, cognitive missteps such as the confirmation bias, priming effects (where you prime the brain to see or hear the world in a certain way), and especially the power of expectation.

Surprisingly, everyone there was most friendly toward me, even though what I was basically telling them is that pretty much everything they believe about the paranormal is wrong. Many came up after to tell me that they too are skeptical of many of the phony baloney scam artists there are out there who are ripping people off with various flim flams, but of course they added the proviso that not all paranormal phenom are perpetrated hoaxes and that they like science because it can help them to discriminate between the true and false paranormal patterns. Okay, whatever it takes to get people interested in science, however, I did make it clear that to date science has yet to find any conclusive evidence for ESP and the like, so that instead of turning to the paranormal as an explanation for presently unsolved mysteries, why not just leave it as a mystery until science can explain it? In science, I noted, it’s okay to say “I don’t know.”

Here’s some iPhone pics I snapped while waiting for my talk to begin. Included is a pic of Frank Sumption and I. Frank is the inventor of “Frank’s Box,” which I wrote about in the January, 2009 issue of Scientific American. Frank’s Box is also called the “Telephone to the Dead,” and consists of a simplified radio receiver that cycles through the stations at breakneck speed such that one only hears snippets of words and sentence fragments, and it is here where the dead allegedly sneak in their messages to us living (or, where in my explanation, the “patternicity” happens, or the natural tendency to find meaningful patterns in random noise. I also snapped some pics of Bruce Goldberg, with whom I once appeared in the mid 1990s on a television show about past lives. Bruce is still churning out the self-published books, now on how he communicates with time travelers from the future. Finally, I will admit that New Agers have the coolest crystals.

Long long ago, in an environment far far away from the modern world, humans evolved to find meaningful causal patterns in nature to make sense of the world, and infuse many of those patterns with intentional agency, some of which became animistic spirits and powerful gods. And as a social primate species we also evolved social organizations designed to promote group cohesiveness and enforce moral rules.

People believe in God because we are pattern-seeking primates. We connect A to B to C, and often A really is connected to B, and B really is connected to C. This is called association learning. But we do not have a false-pattern-detection device in our brains to help us discriminate between true and false patterns, and so we make errors in our thinking: a Type I error is believing a pattern is real when it is not (a false positive) and a Type II error is not believing a pattern is real when it is (a false negative). Imagine that you are a hominid on the planes of Africa and you hear a rustle in the grass. Is it a dangerous predator or just the wind? If you assume it is a dangerous predator and it is just the wind, you have made a Type I error, but to no harm. But if you believe the rustle in the grass is just the wind when it is a dangerous predator, there’s a good chance you’ll be lunch and thereby removed from your species’ gene pool. Thus, there would have been a natural selection for those hominids who tended to believe that all patterns are real and potentially dangerous. I call this process patternicity (the tendency to find meaningful patterns in random noise) and agenticity (the tendency to believe that the world is controlled by invisible intentional agents who may mean us harm). This, I believe, is the basis for the belief in souls, spirits, ghosts, gods, demons, angels, aliens, intelligent designers, government conspiracists, and all manner of invisible agents intending to harm us or help us.

People are religious because we are social and we need to get along. The moral sentiments in humans and moral principles in human groups evolved primarily through the force of natural selection operating on individuals and secondarily through the force of group selection operating on populations. The moral sense (the psychological feeling of doing “good” in the form of positive emotions such as righteousness and pride) evolved out of behaviors that were selected for because they were good either for the individual or for the group; an immoral sense (the psychological feeling of doing “bad” in the form of negative emotions such as guilt and shame) evolved out of behaviors that were selected for because they were bad either for the individual or for the group. While cultures may differ on what behaviors are defined as good or bad, the moral sense of feeling good or feeling bad about behavior X (whatever X may be) is an evolved human universal. The codification of moral principles out of the psychology of the moral sentiments evolved as a form of social control to insure the survival of individuals within groups and the survival of human groups themselves. Religion was the first social institution to canonize moral principles, and God as an explanatory pattern for the world took on new powers as the ultimate enforcer of the rules.

Thus it is that people are religious and believe in God.
