Bohm, Pribram and the Holographic Model

David Bohm was an exceptionally creative physicist who developed a radical reinterpretation (or theory) of quantum physics. His position on theories is that they are explanatory narratives, which in earlier times might have been called myths. Originally, a myth was a story that conveyed a truth that was too difficult or complex to describe in ordinary language. Today myth has taken on the connotation of a fanciful story with no implicit truth, which is not the sense in which myth is being used here. Bohm thinks that one problem prevalent in science today is the confusion of theory with reality. His one-time colleague Albert Einstein agreed and often reminded scientists that theories were only models of or approximations of reality, not descriptions of reality itself. Bohm says that theories can lead to hypotheses that can be tested and determined to have validity and are accepted tentatively. A theory can never be proven, only determined to be more or less useful in generating hypotheses and in helping one understand the phenomena they address.

Traditional science, according to Bohm, sees phenomena in the universe as either ordered or random, which is challenged by Bohm’s theory.

The principal components of David Bohm’s theory:

I.              Holomovement: A quantum field (QF), which is nonlocal and a unified and      integrated whole. Imbued with consciousness, intelligence and meaning.

A.              Super Implicate Order: Super quantum potential (infinite) is the source of the field of quantum potential (Q) that gives rise to the Implicate Order.

B.              Generative Order: Q serves as the carrier of information that determines the characteristics of each particle, relates every particle to every other particle and imbues the QF with order.

C.              Implicate Order arises from quantum potential (Q) and is the source of creativity and material forms.

a.              Formative Order – a blueprint for the material order.

b.              Material Order – the unfolding of the blueprint as wave forms that are perceived as the physical universe. The wave forms are enfolded back into the Implicate Order carrying modifications to their information content that adjusts the blueprint.

D.              Explicate Order: Three-dimensional reality, which is a derivative of a multidimensional reality. The particles comprising matter in the Explicate Order are energy that can be thought of as condensed or “frozen” light.

 For more detail see my essay: Bohm’s Reformulation of Quantum Physics

Bohm says that everything has order but some states of order can only be seen from a higher perspective (implicate order). This is known as hidden order because it is not manifested but enfolded in the implicate order. By way of analogy, Bohm describes a vessel containing glycerine and a small glob of ink. The glycerine in the vessel can be rotated with a crank. When the glycerine is spun the glob of ink spreads out until it is no longer visible (enfolded). When the spin is reversed the glob of ink will reconstitute itself into a visible glob (unfolded). Here is an illustration using the same principle to mix and separate colors.

Bohm uses holographic photography as a metaphor for the nature of reality. He says that there is a striking similarity between a hologram and his principle of wholeness, which he talks about as the quantum field or as the holomovement. When simply inspected with the eye, a hologram looks random and disordered. However, project a laser light through the interference pattern that comprises the hologram, and you get the projection of a 3-D image or order. The order can be unfolded from any piece of the holographic image because the enfolded pattern is distributed throughout the film. Bohm describes the holomovement as being like a dynamic hologram. You can see a rough approximation of the difference by looking at a static holographic image and then watch a virtual performance by holographic projection.

The physical universe or explicate order is a partial unfolding of the whole order enfolded into the implicate order. Living entities can experience the explicate order because they have a nervous system capable of unfolding the projected energy forms or wave forms into apparent material forms or images of material manifestations. (See this book: The Case Against Reality by Donald Hoffman or see a video presentation here by clicking on An Interface Theory of Reality here.

Bohm says that because the universe is a projection of a holomovement, it is ultimately meaningless to view the universe as composed of parts. A part is just an aspect of the holomovement that we have given a name. Thus, separate “things” are just mental abstractions for our convenience. He argues that in the long run, there is a limit to the usefulness of fragmenting the world in this way and could put us on a path toward extinction, if not understood and put in its proper place.

 Viewing the universe as a holomovement doesn’t mean that aspects of the the holomovement can’t have unique properties. Consider whirlpools in a stream. Each whirlpool has unique properties such as structure, size, speed of spin, duration and so on. However, the whirlpool is still nothing more or less than water. (see this book: Why Material Reality is Baloney by Bernardo Kastrup or see a video presentation by clicking on Monistic Idealism here).

Bohm rejects the idea that particles (concentrations of energy) don’t exist until they are observed. He says this idea is another instance of fragmenting aspects of the holomovement into separate phenomena. It is saying that one separate thing (consciousness) interacts with another separate thing (particle). Bohm suggests that any relationship (formative cause) between these aspects (physical and mental) of the holomovement lies enfolded in the implicate order. He also thinks that dividing the universe into living and non-living things, when looked at from the level of the implicate order, is also meaningless.

It appears, however, that these apparent distinctions aren’t entirely meaningless at the explicate level. Differences between things appear to be necessary for experience in physical reality. Niels Bohr, one of the founders of quantum physics and the originator of the concept of complementary pairs, suggested these pairs apply beyond the field of quantum physics. At the implicate level, the pair is in a state of unity but at the explicate level the unity is represented in the form of two aspects. For example, consider the pair hot and cold. If this complementary pair didn’t exist, then the experience of temperatures would not be possible because there would be no range for its expression. The same could be said for many such pairs, including male and female, good and bad, etc. Apparently, diversity is necessary for experience. Absent experience, what would be the point of material reality?

Finally, Bohm says we view ourselves as physical entities moving through what we perceive as space. However, we are actually more like a blur of interference patterns enfolded throughout the universe. In a nutshell, Bohm is trying to move physics from a rigid, mechanical model to a dynamic, organic model.

Karl Pribram was a neuroscientist who studied memory and in particular was interested in where memory is stored. He had become frustrated in his attempts to understand this when he learned of holograms. He took the hologram as a possible model of how the brain stored memory. He proposed that memory was a holographic pattern distributed or enfolded across the brain rather than stored in a specific location. As he studied the holographic model, he became aware of and was influenced by Bohm’s work.

Pribram proposed that what is unfolded is a vast symphony of vibrating wave forms that he calls a frequency domain, which he equates with the interference patterns that unfolded from the implicate order and from which we create our experience of the universe. He sees the brain as a hologram enfolded into a holographic universe. This gives the brain the ability to perceptually represent the wave forms into what we perceive as material objects. He also suggests that our experience of the material world is analogous to the phantom limb phenomenon; i.e, a perceptual illusion experienced as material reality.

Even Pribram’s idea that we are a holographic mind/brain interpreting a holographic universe is just another mental abstraction. Once again we are attempting to take two aspects of the holomovement and create two separate “things” that ultimately cannot be separated.

We are not looking at a hologram. We are an aspect of a hologram. The observer is the observed.

Are We Merely Divine Puppets?

          Self-identified denizens of the Absolute (hereafter mystics) declare that reality is an indivisible whole, and there are experiments in quantum physics that support the assertion. The whole referred to is what I think of as Source (a.k.a. God). It follows from this view that if one is an aspect of an indivisible whole then one is not, indeed, cannot be separate from that whole. If one is not separate from the whole then mystics say there cannot be any choices or actions that do not arise from the whole. In short, there can’t be separate “doers.” I think I understand this argument and agree with it up to a point. In fact, I sometimes say that “Ego is the mask God hides behind while pretending to be you.”, which I think captures the point the mystics are voicing; i.e. Source is ultimately behind everything. I agree that should one reach a state of resonance with Source (Self-realization) then one experiences “oneself” to be the Divine behind the mask. However, most people experience compartmentalized or egoic consciousnesses and are not in resonance with Source.

Here is an illustration to make more concrete the idea of being a “doer” when not in resonance with Source. The human body is a living, organic whole. If some cell, not in resonance with the body, launches off on its own and tries to become independent of the whole, what is the result? Cancer. Thus, we might say that the mass of humanity that is ignorant of the whole and often acts in a manner that is not congruent with Source are like cancerous cells that have declared their independence from the whole and launched their own program. Therefore, one might say that egoic consciousness is like a cancer cell and Self-realization is like a spontaneous remission that turns a cancer cell back into a cooperative aspect of the living body and in the process contributes to an improvement in the immune system. Would we say that a cancer cell has no independence of action? Would we say that it can’t be a “doer” of independent actions because the living body is an organic whole? I don’t think so.

A compartmentalized consciousness absent Self-realization is an egoic consciousness. So, how does an ego (I prefer fictive-self) come about. It is produced by resistance to Source or to pure being. Such an ego consciousness makes choices and pursues its own agenda in the world. Perhaps from an Absolute perspective the world is not real but that has no relevance to ego or the fictive-self. To explore this I’ll use a metaphor to explore a fictive-self operating in the world. Imagine waking up and finding yourself in the cockpit of an airplane in flight. There is no one else in the cockpit or in the plane. What are you to do?

You could realize that you are not a pilot and just sit back, relax and leave things to the autopilot. In short, you could just be and enjoy the ride and see what happens. However, the idea of placing your trust in the airplane’s autopilot begins to make you anxious. You imagine all the awful things that could happen if the autopilot should fail and you can’t fly the plane. Fear arises. Thus, fear motivated, you begin to read all of the instrument labels and study the guidance mechanisms. Further, after getting some idea about the function of various mechanisms, you turn off the autopilot and begin to experiment in an attempt to fly the plane. Some of this exploration results in things that almost panic you, some don’t appear to have an effect and some make changes that you are comfortable with. As your explorations continue, you begin to feel more and more like you are making good choices and are learning to fly the airplane. You begin to view yourself as a pilot and are excited about flying. You make a couple of successful landings and takeoffs. You are now confident in yourself as a pilot and are at ease.

However, the truth is that you are in a flight simulator that is so good that you can’t tell the difference between it and a real airplane. You are not actually in an airplane. You are not actually flying. You can’t really crash. You are not actually making any real choices, good or bad. You are not really flying an airplane, and you certainly are not a real pilot. It is all virtual reality. A virtual airplane, virtual choices, virtual outcomes, virtual control and virtual piloting. In short, it is all unreal. It is just a simulation, but you have failed to recognize it as a simulation. However, you have acquired some of the skills necessary for piloting an aircraft.

When some mystics say that reality is a “dream/illusion with no doers,” the implication is that the world as we know it, which includes life, is a simulation. I prefer the metaphor of a computer simulation to dream or illusion, but it isn’t a difference that makes any real difference. According to these mystics, the simulation we call the world is actually on autopilot, but almost every one of us goes through a process similar to the one described above and resists going with the flow, i.e, just being. Resistance results in the autopilot being blocked, a fictive-self created and behavior directed at control of the immediate aspects of the simulation undertaken. Most people are confused by the claim of mystics that there actually is no world, no people, no choices, no one doing anything, etc. Confusion arises due to a failure to recognize that the claim is intended to convey that it is all a simulation (a.k.a. dream or illusion) and not real in the sense that most people tend to think about reality.

The problem here is one of perspective. From the perspective of the mystic, the world and everything in it is virtual and therefore not real. No thing really exists and nothing ever happens. However, from the perspective of most human beings both things and events are real. There are choices and outcomes. There are actions and actors. Each, from his or her own perspective, is right in terms of the reality  perceived. That one perspective is relative and the other absolute means that each looks pass the other and each is certain they have the Truth and perhaps one does.

One must wonder why, if the “enlightened” have the Truth, they think telling others about their phenomenological Truth will have any effect. Conceptual communication can’t capture phenomenological Truth. Of course, the refrain one often hears is that their conceptual communication is a pointer, but it might also be a subtle way of elevating oneself. The ghost of ego past? Personally, I find the “no doer” view no improvement over the deterministic view of causation posited by scientific materialism. What’s the difference between being a mechanistic robot at the mercy of simple determinism and lacking free will* or being merely a puppet dancing to the tune of a divine puppet master?

The risk is that the ignorant believe the mystics. The ignorant would then still live in a relative world but believe in the absolute perspective. It is important to recognize that they believe, not that they know from their own experience. Thus, believing that they live in a simulation, indeed that they are a simulation, and that they don’t have any real choices and can’t take any real actions, they stop taking the simulation seriously. I am reminded of a quote from Fred Davis’ web site, “So long as it “feels” like there are choices, its important for us to make skillful ones.” What happens to the ignorant if they stop taking choices in the relative world seriously and fail to make skillful choices?

Further, I would ask, might there actually be a reason for the simulation? Might encouraging people, virtual or not, to believe that interacting with the simulation is pointless actually be detrimental in some manner? Looking at the matter from a human perspective, one must ask, why would Source (a.k.a. Cosmic Intelligence, the Divine or God) manifest a simulation like the world, if it serves no purpose and the activity of the avatars within it is pointless? Is what we call the world merely a cosmic soap opera created by Source for meaningless amusement?

Many, including myself, reject the idea that Source has no purpose and the simulation is meaningless. So, why is there a simulation? As hypotheses about such things go, I find the hypothesis offered by Tom Campbell, in his trilogy My Big TOE, as likely as any other that I’ve heard. Campbell makes the assumption that evolution, as a process, is implicit in the nature of things or a core aspect of the whole. It applies not only to life, as we experience it but also to Source. The driving goal posited for the evolutionary process is reduction of entropy. He suggests that a simulation is the method used by Source to decrease its entropy and thereby evolve. All of the compartmentalized consciousnesses employed in the simulation are evolving toward a reduction in entropy. Perhaps Source is employing something akin to parallel processing to more efficiently reduce the entropy of the whole. When a compartmentalized consciousness embodied in an avatar arrives at a level of entropy within the simulation that can make a positive contribution to the entropy of the whole, the simulation is transcended, and one continues to progress with greater awareness of being an aspect of the whole.

This perspective is one that has something meaningful to say to the avatars in the simulation (a.k.a. the world). It says they have a purpose and they can make choices and take actions that are meaningful within the context in which they operate. Indeed, they can affect their own state of compartmentalized consciousness by lowering their entropy through those choices and actions. This breaks down their resistance to just being and can bring them to a point where they are available to the Absolute and are in resonance with Source. This in turn serves Source by decreasing the entropy of Source. Perhaps, some or all mystics might argue, based on their experience, that Source is perfect and has no need to evolve. However, why should one believe that the understanding of mystics, still living in the simulation through a fictive-self (even though greatly diminished), is itself complete and perfect. It seems unlikely to me but then who am I but an ignorant puppet compelled by the Divine to write this meaningless essay that serves no purpose.

David Bohm’s Reformulation of Quantum Physics

David Bohm was an eminent quantum physicist. Early in his career he worked with Albert Einstein at Princeton University. With Yakir Aharonov he discovered the Aharonov-Bohm effect. He was professor of theoretical physics at Birkbeck College, University of London and author of several books on quantum physics. He died in 1992. The David Bohm Society.

I.            Holomovement:

The holomovement is a quantum field (QF) outside of space-time in which everything exists simultaneously as a unified whole creating a seamless, multidimensional field that is imbued with consciousness, intelligence and meaning. The QF is a vast sea of light energy in a state of constant flux and is the ground for all that is. The fundamental reality thus created is a unity that is causal but nonlocal. This means that events arising from the holomovement are determined but are independent of space and time (see two Figures, at end).

A.            Super Implicate Order:

Creativity has its roots in the super implicate order, which is governed by the super quantum potential where possibilities are infinite. The super quantum potential is the source of the processes, laws or principles that give rise to the forms that are taken on by quantum potential (Q), which gives rise to implicate orders. Creativity is expressed through the QF as it generates implicate orders in a manner that could be compared to the way in which a fractal algorithm generates ordered forms in a seemingly random process.

B.             Generative Order:

The QF is permeated by and is in correspondence with Q from which both waves and particles arise. Q acts on the entire QF and relates every particle to every other particle. Q does not carry energy but rather information. The effect that Q has on a particle is determined by Q’s form and the information carried by Q determines its form. Form is the structure, pattern, shape or organization conferred on a particle by Q. It is distinct from the particle itself and is analogous to the way the rules of syntax are independent of a sequence of words forming a sentence but guide its formation. Thus, Q can be thought of as the formative cause that guides the activity of a particle.

Order is dynamic and controlled by the information available in a specific context. What appears random in one context will be seen to be part of an ordered pattern in a broader context where more information is available. For example, evolutionary theory attempts to create an orderly description from apparently random events. Bohm’s model, however, suggests that what appear to be random events are actually embedded in a higher order that provides a broader context in which the random events become part of an orderly pattern. Order exists along a spectrum of orders that represents an open and potentially infinite system. For example, when a mystic perceives the reality of an implicate order, the mystic’s context has been enlarged or broadened. However, the level of detail or content available will be less than that perceived by a physicist from the context existing in the corresponding explicate order.

  C.            Implicate Orders:

               1.            Formative Order:

             Bohm’s second implicate order. The subtle level of formative, organizing and creative activity. The “blueprint” for the material order.

               2.            Material Order:

             Bohm’s first implicate order (first in the sense of being the first level above the explicate  order). At this level particles (the basic building block for matter) undergo rapid creation  and annihilation causing matter to appear to be blinking on an off. Particles are created by  the convergence of waves in the QF causing an interference pattern or ripple referred to  as a wave packet. The process described as “blinking” is also referred to as enfolding and  unfolding and as projection and injection. A particle is explicated, unfolded or projected  into the explicate order and then implicated, enfolded or injected back into the implicate  order. One complete cycle is called a moment. The more rapid this process the greater the  appearance of seamless continuity as perceived from the explicate order. It is the unfolding of the implicate order to produce the explicate order that creates the perception of time. The more separation between unfolding and enfolding the less apparent is continuity and the more events appear to be random. For example, when an electron  appears to “jump” unpredictably from one position to another, the amount of separation in the electron’s moment causes it to display what appears to be random, discontinuous activity. One way that this can be thought of is as a series of photos. When presented  slowly, one merely has a set of individual pictures, which may appear random. When presented rapidly, one has a movie.

  D.            Explicate Order or Three Dimensional Reality:

Three dimensional reality is a derivative of multidimensional reality. The appearance of direct causal connections in the explicate order are actually representations of relationships in the implicate order. Bohm’s model indicates that space-time was enfolded into the implicate order and was explicated in a pulse of light energy (comprised of all waves that move at the velocity of light). This pulse is now described as the big bang, which brought our expanding universe into existence. In some ways, matter can be thought of as condensed or “frozen” light. Since the QF is infinite and eternal, there is no reason to doubt that there are other universes created in the same manner.

Physical (soma) and mental (significance) are reciprocals of one another and there is a two-way flow of energy and information between them. Each significance has a corresponding soma structure. The relationship between soma and significance is meaning. Meaning is roughly equivalent to consciousness and spreads out over a spectrum. Consciousness thus is implicit in all matter in 3D reality but consciousness is not equivalent to self-awareness. The deeper meaning is enfolded into the implicate order the more subtle it is. The perception of shades of subtle meaning requires insight and cannot be attained through analysis alone. A change in meaning changes soma and a change in soma changes meaning. Content is meaning extracted from a given context.

Formative cause is similar to meaning and gives form to the activities of an entity as well as goals toward which the entity is moving. In a sentient being consciousness is its formative cause and thus a sentient being has the ability to self-direct its activities and the goals toward which it is moving; i.e., the being can exercise free will.

The manifest world provides a display. The 3D world then is like a computer monitor that allows the display of relationships between objects and events that are free to vary and create new relationships within limits imposed by the underlying software. Having a display allows consciousness or intelligence to become active. Recall that the pulse between the implicate and explicate order is two-way. The explicate order enfolds or injects information back into the implicate order. The implicate order then assimilates this information and incorporates it into what is unfolded or projected into the explicate order. The holomovement appears to be experimenting and thereby learning or evolving. A process that implies purpose for the 3D universe.

The above is my less than complete understanding of the presentation of Bohm’s reformulation (or interpretation, if you prefer) of quantum physics taken from the section on Bohm in: Friedman, Norman (1990). Bridging Science and Spirit: Common Elements in David Bohm’s Physics, The Perennial Philosophy and Seth.

Here is an expert opinion on Bohm’s reformulation quoted in the above book. John Bell, of Bell’s Theorem fame, upon reading Bohm’s reformulation said, “…one could see immediately that what he was saying was right.”

 

 

 

Why We Believe

          As a psychologist I have often asked myself, why people seem to easily commit to belief systems? This predisposition is clearly evident in a wide range of human activities. It includes things as diverse as religions, conspiracy theories, political ideologies and pseudo-scientific theories.

Albert Ellis’ rational-emotive theory (see also Foundations sub-section Part I) makes a useful distinction between what he calls rational and irrational beliefs. The former have some objective basis and depend upon evidence. The latter have no empirical basis and their adherents usually have a strong emotional investment in the belief, which is largely supported by faith in its correctness. Ellis’ theory rests upon two assumptions about human nature. First, we have a biological predisposition toward irrational thinking, e.g., over generalization and illogical association. Second, one of the major tasks of socialization is to establish a system of beliefs. It is a major developmental task because belief systems help us interpret our experiences, organize our thoughts and observation and make decisions to act.

The second assumption helps to explain why we adopt beliefs systems. They are to varying degrees useful schema for imposing order on our world, understanding the events in our lives and guiding our behavior. The first assumption indicates why many of the belief systems we adopt are irrational and without empirical foundation.

What might be the basis for the assumed predisposition for irrational thinking? Michael Gazzaniga found evidence, in his research on the brain, for what he calls the Left Brain Interpreter (LBI). Gazzaniga thinks that the LBI is a function of the brain acquired through evolutionary selection pressures. The LBI evolved because being able to organize and explain experience has survival value. Having an explanation for a phenomenon, even an incorrect explanation, makes it easier to interpret and respond quickly. If our beliefs lead to successful responses more often than not, this success would give an ability to use explanations to quickly evaluate and respond survival value. While it is often the case that our beliefs lead to successful responses, such success doesn’t necessarily make them valid. However, we usually take success as evidence confirming the correctness of our belief. For example, if you believe that people who look different aren’t trustworthy and are potentially dangerous, you will avoid contact with such people. If you then find that you are seldom assaulted, you will probably attribute your safety to avoiding contact with people who look different from you. Of course, the absence of assault experiences may be due to entirely different reasons but it will be attributed to the belief that motivated your avoidance behavior.

Since we have a strong disposition to formulate explanatory beliefs about our experiences, why do we so often formulate inaccurate and incorrect beliefs or explanations? This happens in part because evolutionary pressures favored those who quickly formulated explanations about experiences. The day-to-day struggle by our predecessors to survive allowed few opportunities for reflection. In the evolutionary environment that led to human beings the quick-witted were usually survivors and the reflective were often someone’s dinner. Thus, we acquired a disposition to formulate beliefs or explanations on the basis of little or no information and what information we had was frequently incorrect.

Frank Barron, a creativity researcher, pointed out many years ago that his research suggested that an inability to explain something made most people anxious or uneasy, which of course provides an incentive (anxiety reduction) to conjure up an explanation or accept some proposed explanation. This is possibly a motivational component to the evolved predisposition to create explanations. Barron found that most people would accept almost any explanation rather than live with uncertainty. He also found that among creative people the opposite was generally true. In short, a small minority of people would rather live with uncertainty than accept a dubious explanation. Barron would probably agree with Steven Pinker, a contemporary psychologist, who has suggested that the human mind frequently functions less like a chief executive and more like a “spin doctor” that is always busy creating post hoc explanations for our decisions and actions.

 There are many examples of this near compulsion to create explanations in human history. One need only think about the many, varied and incorrect beliefs that societies have created to explain natural events, e.g., floods, volcanic eruptions, failed crops, plagues, etc. In many cases, these beliefs have led to behavior that, from our perspective, was irrational. An irrational belief arises in one or more individuals and if it has appeal is adopted by others and often becomes a cultural belief that is perpetuated through the socialization process.

Ellis contends that our tendency to think irrationally results in distortions, flaws, and inaccuracies in our thinking. Parents, peers, community institutions (e.g., schools, churches, political parties, etc.), and the media can introduce distortions into our belief systems. Not only are distortions possible in commonly held beliefs, but personal aspects of our belief system are also prone to distortions that result from our own faulty thinking. Cognitive psychologist Yaakov Kareev’s research has identified one particularly important source of distortion in human thinking. His research has demonstrated a tendency in humans to find positive cause-and-effect associations among events. In fact, he found that people are more likely to see a positive association between two observations than a negative association even when a valid negative association is present. When we attempt to understand an event, we can usually only identify a few of the apparent components of the event. Further, due to limitations in our working memory capacity, we can only consider a small number of the apparent components at one time. Kareev and his associates have shown that our strong predisposition to find positive associations between things that appear to be associated with an event increase as the number of variables in working memory decreases.

There are differences between people in working memory capacity due to differences in cognitive abilities and due to differences in temperament, which make some people more susceptible than others to seeing false connections between events. Anyone who is susceptible to anxiety may experience a reduction in working memory capacity because anxiety has been shown to reduce working memory capacity. As the size of working memory decreases the likelihood of finding false positive associations increases. A predisposition to find positive associations among things we observe and experience has positive benefits, such as, making it easier for a young child to make associations between vocal sounds and environmental stimuli during language acquisition. It also makes it possible and even likely that we will develop cause-and-effect associations that are erroneous. This tendency to make erroneous cause-and-effect associations is sometimes called magical thinking and is most clearly reflected in superstitious and delusional behavior. In addition to our susceptibility to magical thinking, there are many other common errors in thinking that we are prone to make. In fact, Massimo Piattelli-Palmarini has investigated and compiled a catalog of errors in thinking common to human cognition.

Finally, Gazzaniga indicates that once a belief is established it is difficult to change it. There are several reasons beliefs are difficult to change. First, we find it easier to think of evidence for rather than against a personal belief; that is, validating evidence is easier to recall than contradictory evidence. Second, we also have a strong tendency to look for evidence that supports our beliefs and to ignore evidence that does not. Third, when we encounter ambiguous evidence we are disposed to interpret that evidence so that it supports our beliefs. Finally, when we are confronted with evidence that directly conflicts with our beliefs, we are inclined to discredit the evidence rather than change our beliefs. The single best antidote for irrational thinking that we have developed is the scientific method.
