On Saturday, September 12, after flying 17 hours from Cluj, Romania to Budapest, Hungry to Zurich, Switzerland to L.A.X., I drove straight to the Queen Mary in Long Beach, where there was a big paranormal conference hosted by Dave Schrader of Darkness Radio. Dave is a very open-minded fellow, in the sense that he thought it might behoove his flock to have them hear what scientists think some plausible natural and normal explanations there are for the various supernatural and paranormal phenomena that his members tend to believe in and talk about at such conferences (there was even a ghost hunting expedition on the Queen Mary later that night, but I was wasted from flying for so long and passed on being spooked on the ship).

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.

Did humans evolve to be religious and believe in God? In the most general sense, yes we did. Here’s what happened.

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.

I don’t think religious beliefs are different from any other kind of beliefs: political attitudes, commitments to political parties, or economic ideologies, for example. These are all forms of belief. I think at the base of it is this whole idea that we’re pattern-seeking primates. We connect the dots — A connects to B connects to C — and often, they really are connected, and that’s called associative learning. All animals do it. It’s a biological imperative; we grow new synaptic connections when we learn something.

The problem is that there’s no baloney detection module in the brain that says, “That’s a true pattern; that’s a false pattern” with some consistent algorithm that helps us discriminate those. We tend to assume all patterns are real and that they’re infused with intentional agency. And that’s where I think the belief in spirits and ghosts and souls and gods and God and conspiracy theories and so forth comes in. (continue reading…)

You don’t have to look far for claims of the miraculous. But what constitutes a “miracle” and do Christian beliefs in this area make sense?

Michael Shermer, a well-known atheist, says miraculous claims always have a natural explanation. Adrian Holloway is a London Pastor and apologist. He claims to have witnessed the miraculous and says that Michael’s skepticism is unjustified.

Belief, disbelief and uncertainty generate
different neural pathways in the brain

During an early episode of the über-pyrotechnic television series MythBusters, Adam Savage was busted by the camera crew for misremembering his predictions of the probability of an axle being ripped out of a car, à la American Graffiti. When confronted with the unmistakable video evidence of his error, Adam sardonically rejoined: “I reject your reality and substitute my own.” (continue reading…)
