Dr Caroline Leaf and the nonsense of ‘negative’ thinking.

Screen Shot 2016-02-09 at 7.08.49 PM

The power of positive thinking. It’s like rust on our collective consciousness, an idea that’s seems virtually impossible to eradicate, slowly eating away at our collective psyche. The idea has become so ingrained in our culture that it’s part of our folklore and our idiom, and it continues to be deliberately perpetuated by success coaches, business leaders and others who make a very tidy living by peddling baseless optimism. It’s been repeated so often that the ‘power of positive thinking’ has become an Availability Cascade (a self-reinforcing process by which an idea gains plausibility through repetition).

Herbert and Forman summarise it nicely, “The ideas that thoughts and beliefs lead directly to feelings and behavior, and that to change one’s maladaptive behavior and subjective sense of well-being one must first change one’s cognitions, are central themes of Western folk psychology. We encourage friends to ‘look on the bright side’ of difficult situations in order to improve their distress. We seek to cultivate “positive attitudes” in our children in the belief that this will lead to better academic or athletic performance. Traditional cognitively-oriented models of CBT (e.g., CT, stress inoculation training, and rational emotive behavior therapy) build on these culturally sanctioned ideas by describing causal effects of cognitions on affect and behavior, and by interventions targeting distorted, dysfunctional, or otherwise maladaptive cognitions.” [1]

Dr Caroline Leaf is a communication pathologist and a self-titled cognitive neuroscientist. She is one of the many that continue to perpetuate the myth of positive and negative thinking.

Today’s social media meme was yet another promotion of this misguided idea, and to top it off, she misquoted scripture again in an attempt to reinforce it.

“If you randomly allow any negative thought into your mind damage can ensue on a mental & physical level. ‘We destroy every proud obstacle that keeps people from knowing God. We capture their rebellious thoughts and teach them to obey Christ.’ 2 Corinthians 10:5 NLT”

Lets quickly break meme down to see exactly why Dr Leaf is, yet again, misleading her audience.

1. The mind does not control the brain

Dr Leaf’s meme implies that negative thought damages us mentally and physically. The problem with that is that the mind doesn’t control our brain or our body, so negative thought can’t damage us mentally or physically.

Instead, it’s our brain that gives rise to, and controls our thoughts and feelings. We don’t see what goes on ‘under the hood’ so to speak, we only experience our thoughts and feelings, so we assume that regulate each other. But it’s our brain and a number of other processes that are responsible for generating both our thoughts and feelings (CAP blog).

‘Negative’ thoughts can sometimes be the result of damage to our brain, but ‘negative’ thoughts don’t damage the brain.

In fact, often the so-called ‘negative’ thoughts are actually good for us.

2. Negative thinking is normal and healthy

Dr Leaf’s meme also implies that we control the content of our thoughts by suggesting that we ‘allow’ negative thoughts into our minds. But negative thoughts are meant to be there, which is why we have them. ‘Negative’ thoughts have a positive function. We need them to survive.

For example, we have a fear response to prevent us from continually putting ourselves in danger. We have an anger response to motivate us through difficult obstacles. We have feelings of embarrassment to help maintain social cohesion. As Skinner and Zimmer-Gembeck state, “adaptive coping does not rely exclusively on positive emotions nor on constant dampening of emotional reactions. In fact, emotions like anger have important adaptive functions, such as readying a person to sweep away an obstacle, as well communicating these intentions to others. Adaptive coping profits from flexible access to a range of genuine emotions as well as the ongoing cooperation of emotions with other components of the action system.” [2]

Dr Leaf isn’t helping anyone with her meme today. She’s simply promoting an outdated and unscientific notion, encouraging her audience to suppress normal, helpful adaptive functions for fear of harm that’s not scientifically possible.

Then as if to add insult to injury, she follows up her misleading meme with an equally misleading misrepresentation of 2 Corinthians 10:5.

3. Taking every thought captive?

2 Corinthians 10:5 is Pauls famous scripture about taking every thought captive, a concept which seems to support Dr Leaf’s ideas, except that Paul isn’t speaking generally to us, but specifically about the Corinthian church. Look at the verse in context:

“By the humility and gentleness of Christ, I appeal to you – I, Paul, who am ‘timid’ when face to face with you, but ‘bold’ towards you when away! I beg you that when I come I may not have to be as bold as I expect to be towards some people who think that we live by the standards of this world. For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. And we will be ready to punish every act of disobedience, once your obedience is complete.
You are judging by appearances. If anyone is confident that they belong to Christ, they should consider again that we belong to Christ just as much as they do. So even if I boast somewhat freely about the authority the Lord gave us for building you up rather than tearing you down, I will not be ashamed of it. I do not want to seem to be trying to frighten you with my letters. For some say, ‘His letters are weighty and forceful, but in person he is unimpressive and his speaking amounts to nothing.’ Such people should realise that what we are in our letters when we are absent, we will be in our actions when we are present.” (NIV UK, 2 Corinthians 10:1-11)

This chapter is a specific rebuke to some of the Christians within the church at Corinth, and also a defence against some of the murmurings and accusations that some in that church were levelling at Paul. For example, in verse 2, “I beg you that when I come I may not have to be as bold as I expect to be towards some people who think that we live by the standards of this world.”

Verses 3-6 are a specific and authoritative rebuttal against the accusations levelled at Paul, paraphrased as, “You may speak against us and the church, but we have weapons that smash strongholds, and we’re coming to take down those pretensions of yours and take every thought of yours captive to make it obedient to Christ, and punish every act of disobedience …”

The specific nature of the verse is also supported by some Bible commentary: “But how does St. Paul meet the charge of being carnally minded in his high office? “Though we walk in the flesh [live a corporeal life], we do not war after the flesh,” or “according to the flesh,” the contrast being in the words “in” and “according.” And forthwith he proceeds to show the difference between walking in the flesh and warring according to the flesh. A warrior he is, an open and avowed warrior – a warrior who was to cast down imaginations and every high thing that exalteth itself against the knowledge of God, and bring into captivity every thought to the obedience of Christ; a warrior too who would punish these Judaizers if they continued their disorganizing work; but a prudent and considerate warrior, deferring the avenging blow till “I am assured of your submission” (Stanley) “that I may not confound the innocent with the guilty, the dupes with the deceivers.” What kind of a preacher he was he had shown long before; what kind of an apostle he was among apostles as to independence, self-support, and resignation of official rights in earthly matters, he had also shown; further yet, what kind of a sufferer and martyr he was had been portrayed.” (C. Lipscomb – http://biblehub.com/commentaries/homiletics/2_corinthians/10.htm)

Similarly, the translation from the original text is more specific than general. The verb used for “bringing into captivity” is aichmalōtízō, “to make captive: – lead away captive, bring into captivity” which is in the Present Active Participle form of the verb. The present tense represents a simple statement of fact or reality viewed as occurring in actual time. The active voice represents the subject as the doer or performer of the action. The Greek participle corresponds for the most part to the English participle, reflecting “-ing” or “-ed” being suffixed to the basic verb form. Actions completed but ongoing or commands are different verb tenses (see https://www.blueletterbible.org/help/greekverbs.cfm for a better explanation). So Paul wasn’t making a general statement, but a specific statement about what he would do in his present time, not the future.

So, Paul isn’t telling us to “bring every thought captive into obedience to Christ”. Dr Leaf is perpetuating a common scriptural misunderstanding.

A verse which better clarifies what God wants for our thought life is Paul’s exhortation to the Philippian church in Philippians 4:8, “Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable – if anything is excellent or praiseworthy – think about such things.” Both the context, and the form of the verb, suggest that this is an ongoing command. And it makes better sense too. If we spend all of our time trying to fight against every thought that comes into our head, we’d become exhausted, but we can divert attention to those things that are worthy of our attention. And in many ways, what Paul is encouraging is what would be considered now as simple meditation, which is more scientific than the power of positive thinking.

The moral of this story … ‘negative’ thoughts and feelings don’t do us damage, but trying to unnecessarily suppress them does.

Dr Caroline Leaf and the Mental Monopoly Myth (Mark II)

 

Screen Shot 2015-10-02 at 9.27.19 pm

In my last post, I asked the question, “What’s more important to a person’s health and well being?” and I showed that Dr Caroline Leaf proposition that the mind dominates ones mental health and well-being is patently false.

Not to be outdone, Dr Leaf countered today with a tweak to her initial proposition: “Mind-action is actually THE predominant element in mental well-being.”

Dr Caroline Leaf is a communication pathologist and self-titled cognitive neuroscientist. She’s also started calling herself an expert in mental health, despite never having trained in medicine or psychology, or working in counselling.

Dr Leaf may have tightened up her wording from her previous statement, but her claim that mind-action is the predominant element in mental well-being is still wrong, because her fundamental assumption is wrong.

What fundamental assumption? That the brain doesn’t control the mind, but the mind controls the brain.

As I discussed in the last post, this idea of the mental monopoly dominates every one of Dr Leaf’s works, and most of her social media memes. Take her most recent meme for example, published just today, “The brain is not a chemical stew that is missing a key spice! The brain is hugely complicated and complex and is controlled by the even more hugely complex and eternal mind!”

The premise that the mind controls the brain is wrong. Completely and utterly wrong. It is precisely the opposite of what science tells us. The mind is a function of the brain, just like breathing is a function of the lungs. No lungs, no breath. No brain, no mind. (see my posts here, here and here, and others for further discussion)

consistencydemotivator

It’s been said, “Consistency: It’s only a virtue if you’re not a screwup.” Perhaps that’s a little harsh, but it does illustrate the point that just because you say something often enough, doesn’t make it true. So no matter how many times Dr Leaf repeats herself, the fact that the brain controls the mind isn’t going to change.

Even without appealing to the plethora of scientific information out there, Dr Leaf’s claim that mind-action dominates mental well-being is wrong, since mind-action is simply brain-action, which in turn, is influenced by the complex interplay of our genes, our physical health, our uncontrollable external environment, our social networks and our spirituality. Our mental well-being is no different to our general well-being in this regard. It is still part of the complex interplay that is represented by the biopsychosocial (and spiritual) model.

It’s time for Dr Leaf to update her teaching, and abandon her unscientific presuppositions and philosophies.

Dr Caroline Leaf – Better graphics, same content

Screen Shot 2015-09-04 at 2.08.15 pm

In the world of marketing, visual media is king. Humans are sight based creatures. About thirty percent of our brains cortex is dedicated to vision , compared to 8 percent for touch and 2 percent for hearing http://channel.nationalgeographic.com/brain-games/articles/brain-games-watch-this-perception-facts/)

It’s no wonder then that sites like Pinterest and Instagram have so rapidly become such dominant sites on the social media landscape. And why billions of dollars are invested in visual advertising on TV and billboards.

Dr Caroline Leaf is a communication pathologist and self titled cognitive neuroscientist. In the last few weeks, she’s gone for a new look for her Instagram and Facebook posts – gone are the simple lines, plain text and stand alone logo. Her posts have gone glam, with backgrounds of her photo treated with coloured layering and shading, overlaid with Dr Leafs favourite text. Sometimes the text is pretty easy to read. Other times it looks like a 4th grade class got to take turns picking the font and text size for each different word. But hey, it’s edgy, it’s happening, it’s so hot right now.

It’s a real shame that she only chose to update the look and not the actual content of her social media memes. Take today’s offering as an example: “The mind processes. The brain reflects this processing.” (The unsaid conclusion being that, “The mind controls the brain.”)

I’ve written about this meme a few times (here, here, here and here, as a small sample). But let’s relook at it again, since Dr Leaf is unwilling to reconsider the statements lack of validity.

Does the mind really control the brain, or does the brain control the mind? Well, if the mind was separate from the brain and controlled the brain, then the mind would be able to function independently of the brain. And also, if the mind was separate to the brain, then changes to the brain would not influence the function of the mind.

It’s difficult to show that a person has a mind without a brain. You can’t really remove someone’s brain and then put it back again, so not many people are keen to volunteer for that study. But anecdotally, have you ever heard of a person who has woken from a coma having spend all that time in deep thought?

What IS much easier to study, and has been proven over the course of centuries, is the change to our cognitive function when our brain is changed, physically or functionally.

The mind changes when the function of the brain is changed by medications.
The mind changes when the function of the brain is changed by illicit drugs.
The mind changes when the function of the brain is changed by electrical stimulation.
The mind changes then the structure of the brain is changed by tumours or injuries.

In 1848, a man named Phineas Gage was packing gunpowder in some rock when an accidental detonation blasted a foot-long iron rod through the left face and forehead, severely damaging the left frontal lobe of his brain. History records that his personality changed from polite, well mannered, and well spoken to fitful, irreverent, impatient of restraint or advice, obstinate and capricious [1].

Whilst Phineas Gage was is most famous, other brain injuries can also change the way in which someone thinks. For example, lesions of the parietal lobe of the brain changes the way people see their own bodies. Baars writes, “Patients suffering from right parietal neglect can have disturbing alien experiences of their own bodies, especially of the left arm and leg. Such patients sometimes believe that their left leg belongs to someone else (often a relative), and can desperately try to throw it out of bed. Thus, parietal regions seem to shape contextually both the experience of the visual world and of one’s own body.” [2]

Some might argue that the mechanism of injury might be the variable that could change someone’s personality. After all, if an iron rod was blasted through my skull, I might be a little antsy too. But other structural change to the brain, not associated with a sudden traumatic event, can also result in personality changes – it’s well recognised that personality changes can be the first presenting symptom of brain tumours, for example.

Though the brain doesn’t have to be horribly distorted for the mind to change. In the last couple of decades, a tool has been developed called TMS – short for transcranial magnetic stimulation. A magnetic pulse is delivered over a part of the skull, passing through the bone to reach the brain, causing changes to the electrical current running through the nerve cells. Stimulation of different intensities can either turn off the nerve cells or excite them. TMS has become a great tool for studying cognitive neuroscience because it directly changes the function of the brain in a well localised and temporary manner. It’s also easy for scientists to blind the subjects to whether they’re receiving the treatment or a sham treatment, so the results are reliable. Research shows that when the frontal lobes of the brain are changed by the electrical signals, their executive function also changes [3].

Changes to the function of the brain are known to change the function of the mind and have been known to do so for centuries. From religious hallucinogens to Woodstock hippies, drugs of various forms have been used to alter mood, thought, and perceptions of reality. But there’s a drug that’s much more common, that’s known for its ability to alter our brains thinking ability the world over, and even Dr Leaf enjoys it.

Like most people, my morning doesn’t really start until after my first cup of coffee. Sure, I’m functional, but barely. Fifteen minutes after the first short black is in my system, I find that I’m much more alert and my thinking is clearer.

What’s changed? Is it my mind changing the function of my brain, or is it the coffee, specifically the caffeine in it, that’s changing my brain which is in turn is making my mind clearer and sharper? I think the answer is obvious. Caffeine is the most commonly used recreational drug in the history of mankind, and every cup of java (real coffee that is, not the travesty that is decaf) is more proof against Dr Leaf’s dogmatic misrepresentation of basic science.

So, if the mind is changed by alterations to the structure and/or function of our physical brain, it follows that our mind must be a function of our brain. Therefore, the mind does not process, while the brain simply hangs on for the ride. Rather, the brain processes, and our mind reflects this processing.

Dr Leaf can tart up her memes all she likes, but until she changes the content of her memes to match some actual science, it’s all just smoke and mirrors. The truth doesn’t need visual pimping. It is simply the truth.

Dr Caroline Leaf – Manhandling scriptures again

Screen Shot 2015-05-30 at 7.49.02 pm Screen Shot 2015-05-30 at 7.50.30 pm

I recently heard a great quote, “If you take the text out of context, all you’re left with is a con.” It’s a quote that seems to describe Dr Leaf’s social media pings quite nicely over the last twenty-four hours.

Dr Caroline Leaf is a communication pathologist and a self-titled cognitive neuroscientist. She is also a self-titled theologian.

Today she posted, “3 John 2 = Mental Health ‘Beloved, I wish above all things that thou may prosper and be in health, even as your soul prospers.’ Everything relies on your soul, which is your mind, prospering” (original emphasis).

Except that her statement is blatantly false. The soul isn’t just the mind. A simple search of an on-line Bible dictionary reveals that there are a number of ways in which the word ‘soul’ is used, but more specifically to the meaning in 3 John 2, “the (human) soul in so far as it is constituted that by the right use of the aids offered it by God it can attain its highest end and secure eternal blessedness, the soul regarded as a moral being designed for everlasting life”. (http://goo.gl/AjhvNO)

It should also be noted that the two words used in ancient Greek that referred to our inner reality were pneuma (‘spirit’) and psyche (‘soul’). According to Thayer’s Greek Lexicon, the words pneuma (‘spirit’) and psyche (‘soul’) were often used indiscriminately. The Apostle Paul distinctly used the word pneuma separately to the word psyche in 1 Thessalonians 5:23, but nearly every other New Testament writer wasn’t so precise.

Thus, John wasn’t referring to the mind at all, but probably our spirit, or at the very least, our generic soul, not specifically to our mental faculties or our thoughts. The scripture in 3 John 2 doesn’t have anything to do with our mental health.

Yesterday, Dr Leaf tried to merge one of her favourite authors views with scripture. She posted a quote from Dr Bruce Lipton, “Genes cannot turn themselves on or off. In more scientific terms, genes are not ‘self-emergent’. Something in the environment has to trigger gene activity.” Dr Leaf added, “That ‘something’ is your thoughts! Read Proverbs 23:7”.

So I did.   Proverbs 23:7 in the King James Version says, “For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.”

So what is it with the second half of the verse? If this scripture is all about our thought life, then what’s the eating and drinking half of the verse got to do with our thought life?

The explanation is that this verse has nothing to do with our thought life at all. Dr Leaf has simply been misquoting it for years, and no one checked to see if she’s right. According to the Pulpit commentary found on the Bible Hub website, “The verb here used is שָׁעַר (shaar), ‘to estimate … to calculate’, and the clause is best rendered, ‘For as one that calculates with himself, so is he’. The meaning is that this niggardly host watches every morsel which his guest eats, and grudges what he appears to offer so liberally … He professes to make you welcome, and with seeming cordiality invites you to partake of the food upon his table. But his heart is not with thee. He is not glad to see you enjoy yourself, and his pressing invitation is empty verbiage with no heart in it.” (http://goo.gl/nvSYUh)

The other half of her meme comes from Dr Bruce Lipton, an agnostic pseudoscientist who was a cell biologist before he flamed out, and now teaches chiropractic in New Zealand. He believes that there is a metaphysical link between our thoughts and our cell function [1]. He’s ignored by real scientists (http://goo.gl/cX7Aeg).

As for his quote, it’s a misdirection. Sure, genes aren’t self-emergent – they don’t think for themselves. DNA is just a long chemical string which just carries a code, the biological equivalent to your DVD discs. Like a DVD, DNA isn’t worth anything if it doesn’t have a machine to read it. In every cell, there are hundreds of proteins that read and translate DNA. Those machines respond to the external environment, but they also respond to the cells internal environment, and to other genes themselves. Simply put, DNA is decoded by intracellular proteins, but intracellular proteins are only made by the expression of DNA, which happens all the time. A single-celled embryo becomes a baby because of DNA self-copying and expression that happens a trillion times over by the end of pregnancy. So while a single gene can’t turn itself on and off, the genome as a whole is essentially self-controlling, only being partly modulated by the external environment. Genes are turned on and off all the time by other genes through the proteins those genes make. Lipton’s assertion that “something in the environment has to trigger gene activity” is simply nonsense.

So Dr Leaf uses a flawed quote from a pseudoscientist to try and back up her specious interpretation of an out-of-context verse of scripture.

Somewhat poor from an “expert” theologian and cognitive neuroscientist really.

These memes speak to the issues of trust and legitimacy. Dr Leaf can call herself whatever she likes, but how can church leaders continue to endorse her to their congregations as an expert when she consistently misinterprets science and scripture? Can they honestly look their parishioners in the eye and say that Dr Leaf’s teaching is accurate? Can they stand at their pulpits and confidently support her book sales at their back of their churches?

Dr Leaf needs to re-evaluate. She needs to re-evaluate her claims to be an expert in cognitive neuroscience and the Bible. She needs to re-evaluate the quality of information that she relies on. She needs to re-evaluate what she’s trying to achieve in posting to social media, and re-evaluate the accuracy of her memes.

Because ultimately it’s the truth that sets people free, not errant opinions and misinterpretations.

Dr Caroline Leaf – Contradicted by Dr Caroline Leaf

“Who am I?”

It’s one of life’s most fundamental questions. It’s such a quintessentially human question, one that speaks to the importance of our identity as individuals.

It’s a question that Dr Leaf thinks she has the answer to.

Dr Caroline Leaf is a communication pathologist and self-titled cognitive neuroscientist. Recently she launched an on-line program called “Perfectly You”, based on her 2009 book, “The Gift In You” [1]. In “The Gift In You”, Dr Leaf promised that by using her program, you could enable your gift and increase your intelligence to the level that you desire. According to Dr Leaf, your gift is something that’s hardwired into your brain, which makes your gift uniquely yours. For example, she wrote:

“Your gift lies in something so profound yet so simple that we tend to overlook it: the combination of your life experiences with the measurable structure of how your brain has been wired to think and process information.” (p24)

“Neurologically, you are not wired for someone else’s gift. You can try as hard as you want. You can listen to as many teachings as you possibly can. You can buy all the books with an instant formula for a business mogul’s success. You can adopt all of the popular motivational sayings. But even then, you will never have someone else’s gift.” (p11-12)

“You were not built to struggle. Your brain is wired to function according to a specific sequence. When you discover that sequence, that structure, you unlock great potential.” (p13)

“When you know how your gift is structured, how your brain is uniquely wired, and how to achieve lasting success, you will unlock your truth-value – your gift.” (p17)

“The exciting result of this plasticity of the brain that we hold power over is that no two brains are alike: We are uniquely, fearfully and wonderfully made (Psalm 139:14). There is diversity in brain structure and organisation and function, which results in the way we think and approach life.” (p18)

So according to Dr Leaf, our gifts are something that is uniquely hardwired into our brain, something that we cannot change even if we wanted to, and that brain structure gives rise to the way in which we think and the actions that we take.

Then, as I was rereading this book, I came across a sentence that I must have read before when I first got it, but which I hadn’t fully appreciated the significance of until now.

On page 47, Dr Leaf said,

The mind is what the brain does, and we see the uniqueness of each mind through our gifts. This, in itself is delightful and, intriguing because, as you work out your gift and find out who you are, you will be developing your soul and spirit.” (Emphasis added)

This quote in and of itself isn’t actually that significant until we compare it to a quote from the first chapter of Dr Leaf’s 2013 book, “Switch On You Brain.” [2]

“The first argument proposes that thoughts come from your brain as though your brain is generating all aspects of your mental experience. People who hold this view are called materialists. They believe that it is the chemicals and neurons that create the mind and that relationships between your thoughts and what you do can just be ignored.
So essentially, their perspective is that the brain creates what you are doing and what you are thinking. The mind is what the brain does, they believe, and the ramifications are significant. Take for example, the treatment of depression. In this reductionist view, depression is a chemical imbalance problem of a machinelike brain; therefore, the treatment is to add in the missing chemicals.
This view is biblically and scientifically incorrect.” [2: p31-32] (Emphasis added)

So … Dr Leaf believes that the mind is not what the brain does. So our gifts aren’t uniquely hardwired into our brain, and we should be able to change our gifting if we want to, since it isn’t our brain structures that give rise to the way in which we think and the actions that we take, but it’s all related to our choices.

This must be really embarrassing for Dr Leaf, to so directly call your own beliefs biblically and scientifically incorrect, and then not to notice.

Now, we all make innocent mistakes. No one is perfectly congruent in everything they say. But this isn’t just getting some minor facts wrong. These statements form the foundation for Dr Leaf’s teaching, and are in print in two best selling books, from which she has used to present to countless churches and seminars around the globe.

Which makes her major self-contradiction important for three reasons:

  1. It calls her self-titled expertise as a cognitive neuroscientist into question.
  2. It calls her teaching into question.
  3. It calls her ministry into question.

Firstly, in majorly contradicting herself, Dr Leaf shows desperately little basic knowledge about cognitive neuroscience. Even first year neuroscience students consistently know how the brain works, and are able to build on this to grow their knowledge about the brain. The fact that Dr Leaf can’t get her basic facts straight on something so fundamental as the relationship of the mind and the brain clearly demonstrates that she is not the expert in cognitive neuroscience that she claims to be.

Secondly, in majorly contradicting herself, Dr Leaf undermines all of her teaching. If she can’t be trusted to consistently state basic facts on which she is supposed to have high level training, then how can she be trusted with anything more complicated scientifically. Indeed, how can she be trusted to interpret scripture, in which she has no formal training. Thus, her whole ministry is now thrown into doubt. Dr Leaf may get some facts right in the rest of her writing and in her teaching, but unless you’re an expert in the field, it would be impossible to know. And since she doesn’t reference her work properly, it makes it impossible for the average person to go back to her sources and validate her teaching.

Thirdly, in majorly contradicting herself, Dr Leaf makes it very difficult for churches who have her ministering from their pulpits. Pastors aren’t experts in neuroscience or medicine. How are they supposed to have confidence that what Dr Leaf is saying? How can they be sure that what Dr Leaf is teaching to their congregations is factual or is contradicted by real scientists or her own teaching? How can they be sure that Dr Leaf is not causing some of their more vulnerable parishioners unnecessary harm because her teaching is contradicted by modern science and medicine?

Dr Leaf may believe that she has many answers, and is motivated by the best of intentions. However, to call your own beliefs “biblically and scientifically incorrect” does not instil confidence. Dr Leaf needs to take a serious look at her teaching and the quality of the science that undergirds it, and until that happens, the churches that have invited Dr Leaf to minister from their pulpits should seriously reconsider that decision.

Dr Caroline Leaf and dualism revisited

Screen Shot 2015-01-18 at 9.05.13 pm

Are we a body with a mind, or a mind with a body?

This may sound like a chicken-and-egg type of conundrum, but it’s a deep philosophical question. The concept of the separation of the mind from the body is known as dualism, and has been debated for centuries because the answer to that question then guides a lot of other philosophies and theories.

Dr Caroline Leaf is a communication pathologist and a self-titled cognitive neuroscientist. She believes that the body and brain are separate from the mind, which significantly influences her teaching. Take, for example, her social media meme-of-the-day today. She posted that, “The brain does not change itself… our MIND changes the brain”. If one assumes that the mind is separate from our brain, then its plausible that the mind influences the brain.

Except that it doesn’t. Our mind is a product of our brain, not a separate entity. Neurological damage from injuries or tumours, electrical stimulation of the brain in the lab, the effect of illicit drugs on the brain like LSD or marijuana, and everyday examples like the changes to our thinking under the influence of caffeine or alcohol, all prove that changes to the structure and function of the brain change thought patterns. It isn’t the other way around. Every brain changes itself too – the brain of an embryo or foetus undergoes massive changes but foetuses don’t have streams of conscious thought. Dr Leaf’s meme is scientifically misguided.

Perhaps what is more worrying is Dr Leaf’s use of scripture to try and justify her view that the mind and the brain are separate. To introduce her meme, Dr Leaf wrote, “Read Luke 16:19-31 to see that the mind is separate from the brain – this is God’s divine design.”

There are a number of scriptures that theologians use to discuss the biblical basis for the separation of the body and soul, but Luke 16:19-31 isn’t one of them. That passage is the parable of Lazarus and the rich man.

It says:

‘There was a rich man who was dressed in purple and fine linen and lived in luxury every day. At his gate was laid a beggar named Lazarus, covered with sores and longing to eat what fell from the rich man’s table. Even the dogs came and licked his sores.
‘The time came when the beggar died and the angels carried him to Abraham’s side. The rich man also died and was buried. In Hades, where he was in torment, he looked up and saw Abraham far away, with Lazarus by his side. So he called to him, “Father Abraham, have pity on me and send Lazarus to dip the tip of his finger in water and cool my tongue, because I am in agony in this fire.”
‘But Abraham replied, “Son, remember that in your lifetime you received your good things, while Lazarus received bad things, but now he is comforted here and you are in agony. And besides all this, between us and you a great chasm has been set in place, so that those who want to go from here to you cannot, nor can anyone cross over from there to us.”
‘He answered, “Then I beg you, father, send Lazarus to my family, for I have five brothers. Let him warn them, so that they will not also come to this place of torment.”
‘Abraham replied, “They have Moses and the Prophets; let them listen to them.”
‘“No, father Abraham,” he said, “but if someone from the dead goes to them, they will repent.”
‘He said to him, “If they do not listen to Moses and the Prophets, they will not be convinced even if someone rises from the dead.”’ (Luke 16:19-31, NIV)

I’m not sure exactly where the convincing proof of the separation of our mind and our body is found in this passage. This is a description of the afterlife, and in this parable, the rich man was very specific about memories (“I have five brothers …”) as well as physical sensations (“I am in agony in this fire”) and even parts of the body (Lazarus’s finger, his tongue). Jesus isn’t telling a story of how the mind is separate to the body, but of a different dimension in which the body and the mind are still together. This passage isn’t proof for the concept of dualism, but against it.

Dualism also has a number of fatal scientific and philosophical flaws, in particular that dualism is conceptually fuzzy, experimentally irrefutable, considers only the adult mind, and violates physics, in particular the law of conservation of energy.

So Dr Leaf bases her teaching on a scientifically and philosophically untenable concept and then attempts to use a scripture which refutes dualism in her attempt to support it. That’s audacious, but then to claim that it’s God’s divine design is, at best, a little brazen.

Dualism may be one of her fundamental philosophies, but I think Dr Leaf should review the basis for it, and possibly reconsider her reliance on it.

Going green – why envy is an adaptive process

The Bible says, in Job 5:2, “For wrath kills a foolish man, And envy slays a simple one.”

A German proverb goes, “Envy eats nothing, but its own heart.”

Dr Caroline Leaf, communication pathologist and self-titled cognitive neuroscientist, posted today on her social media feeds, “Jealousy and envy creates damage in the brain … but … celebrating others protects the brain!”

Yes, sometimes envy isn’t good for us. Emotions guide our thought process, and like all emotions that are out of balance, too much envy can cloud our better rational judgement and bias our perception of the world. Thankfully, envy doesn’t literally eat out our hearts or literally cause brain damage.

If anything, envy when experienced in a balanced way can actually improve our brain functioning. According to real cognitive neuroscientists, envy and regret are emotions that help us because they both fulfil the role of effectively evaluating our past actions, which improves our choices in the future. As Coricelli and Rustichini noted, “envy and regret, as well as their positive counterparts, share the common nature that is hypothesized in the functional role explanation: they are affective responses to the counterfactual evaluation of what we could have gotten had we made a different choice. Envy has, like regret, a functional explanation in adaptive learning.” [1]

When it comes to the human psyche, there is no black or white, good vs evil distinction between different feelings or emotions. B-grade life coaches and slick pseudoscience salespeople dumb down our emotions into a false dichotomy because it helps sell their message (and their books). Every emotion can be either helpful or unhelpful depending on their context in each individual.

As Skinner and Zimmer-Gembeck wrote, “Emotion is integral to all phases of the coping process, from vigilance, detection, and appraisals of threat to action readiness and coordinating responses during stressful encounters. However, adaptive coping does not rely exclusively on positive emotions nor on constant dampening of emotional reactions. In fact, emotions like anger have important adaptive functions, such as readying a person to sweep away an obstacle, as well communicating these intentions to others. Adaptive coping profits from flexible access to a range of genuine emotions as well as the ongoing cooperation of emotions with other components of the action system.” [2]

If you find your thoughts and feelings tinged by the greenish hue of envy, don’t worry, it’s not necessarily a bad thing. Your heart isn’t going to consume itself and you won’t sustain any brain damage. Use envy or regret as tools of learning, tools to help you evaluate your choices so that you make a better choice next time. Having balanced emotions is the key to learning and growing, coping with whatever obstacles life throws at us.
