10 Popular Myths About Right Brain Left Brain Debunked

Want to learn how to master your brain and navigate effortlessly away from the common mix-ups most people have?

Then you’re in the right place.

I’m going to expose the 10 biggest myths about the brain, including ones you hear about being a “right brain or left brain” person.

And for each one, you’ll learn some proven ways to counter them too.

So without further ado, let’s do this!

Myth #1: Believing you’re either a “left or right brain” person

Chances are, once upon a time, during your happy musings on the internet, you came across the idea of the right brain left brain.

This is the myth that you’re either a logical facts driven person (left brain), or you’re a intuitive, arts and imagination type person (right brain).

It’s not true.

Your brain is a very intricate and complex organ. Despite decades of research and study, the brain is something that we still know relatively little about.

Even so, just google “right brain left brain characteristics” and you’re bombarded with pages and pages of results. Each one claiming to tell you which one you are.

This left brain right brain idea originated back in the 1960s, as a result of research done by Roger W. Sperry.[1]

It’s well known that the right and left sides of our brains are different, but can we group people into the left brain people and the right brain people? Is it that simple?

A team of neuroscientists at the University of Utah spent two years testing this out, studying over 1,000 people’s brains to see if it was indeed true. What their research revealed, was that both sides were more or less equal in their activity on average.

“Language tends to be on the left, attention more on the right. But people don’t tend to have a stronger left- or right-sided brain network. It seems to be determined more connection by connection.”  – Dr. Jeff Anderson (lead author)[2]

So be careful when surfing the interwebs. The self proclaimed brain messiah’s aren’t always doing their research, and whilst graphics like above seem cool, they aren’t very accurate. You don’t belong in a box of left brain or right brain.

Lesson:

People aren’t either logical or creative. You can be both.

Don’t limit your thinking and capabilities by believing this myth. You get better at what you work at.

Myth #2: Believing you’re hardwired for happiness

Many people I’ve coached over the years demonstrate this crippling flaw:

We tend to think of our problems, worries, etc. as something unique to us. We mistakenly believe that we are unique in this way.

However, let me reveal something to you having worked with tens of THOUSANDS people from around the world. Something which may surprise you.

Our mental biases and flaws are quite common. We tend to make very similar mistakes.

Instead of personalizing all your problems and over identifying with them. What if you saw the challenges you face as problems created by the brain generally, instead of something you are doing?

Think of it this way:

Imagine you have a faulty mobile phone that can only operate for 2 hours at 100% capacity at a time. Then it needs a short break.

Now, you could view this as a problem with your specific mobile, and get angry and frustrated that you had such bad luck.

Or perhaps, realize the truth.

What if it was just a manufacturing fault? But one you can’t “fix” immediately by going to the Apple Store because it was built two million years ago for a different environment.

Obviously I’m simplifying things a little (Ok, a lot). However the point I’m making is simple:

Advertising

Your problems aren’t unique. We all suffer from them. So plan for the common pitfalls so you can avoid them.

“We have a two million-year-old brain that isn’t designed to be happy, but to survive.”  — Tony Robbins

As the above quote so beautifully summarizes, your brain is designed to help you to survive first and foremost. This mechanism is both deep and complex.

In my work, we often identify these subconscious patterns and make sure they’re running in alignment to the specific goal you desire to achieve.

Something which most people are totally unaware or uninterested in discovering, so they are doomed to repeat the same mistakes again and again no matter how hard they try.

These “software faults” are ones we all experience from time to time:

  • Not feeling motivated to go to the gym
  • Not feeling confident about starting a new project or idea
  • Being randomly affected by weird moods or feelings

But the difference between those who succeed, and those who dabble and get frustrated is simple:

Working on our weak areas consistently and planning for them.

Lesson:

Think of your brain like an old computer, full of some common bugs and viruses we all contend with.

Accept these flaws, learn about how they manifest themselves for you in particular, then work on improving them so you can perform better.

Myth #3: Believing your personality traits are fixed

You have personality traits (often from childhood) that (for most) won’t change.

But before you get demoralized and reach for that jar of chocolate chip cookies again, that doesn’t mean that you CAN’T change.

It just takes work.

Realistically, most people still won’t change their personalities for two reasons:

  • They like the safe, comfortable option of staying the same (let’s face it – it’s quite easy)
  • They don’t know they can change

Fortunately for you, we’ve already dispelled the idea that you cannot change your personality traits. So you’re immediately ahead of most people.

There are so many different theories and ideas about what your personality is, how we can measure it and how it comes to be.

The general consensus is that it’s shaped in the early years of our lives and (generally) stays stable over time.

The most widely accepted is something known as the “Five Factor Model”, stating that there are five basic personality traits that can define us: openness, conscientiousness, extraversion, agreeableness, and neuroticism.

These traits shape and influence how we react to different experiences and events in our lifetime.

But here’s the thing:

Defining events, traumatic experiences can all trigger changes in who we are, and how we are.

One of the latest study integrating 14 longitudinal studies that gathered information about people’s personalities, found that from the Big Five personality traits — all of them showed major fluctuations across individual participants’ lives.[3]

Lesson:

The best way to think of your personality is like a mould of clay. It’s already in a rough shape, hardening over time. But you can work to change and adjust it.

Myth #4: Believing you only use 10% of your brain

This myth is simply not true. If I cut 90% of your brain out, would you still function?

No!

Imagine that what is known about our brains is like the volume inside a balloon.

Imagine that what is unknown is the infinite space outside of the balloon.

The surface of the balloon, the interface between the known and the unknown, represents questions. The larger the volume inside the balloon, the larger the balloon surface.

Advertising

The more we know, the more questions we have.

It’s simply not true that we only use 10% of our brains.

What’s more accurate is that we don’t always perform to our maximum mental capacities.

Different factors — motivation, environment, overall health, sleep — all exert different levels of influence on how close to 100% we perform at any given time.

So why does this myth exist? Why is it so appealing?

Probably because of the untapped human potential it implies that we have huge pools of dormant mental powers, which if used, could help us achieve so much more.

Lesson:

We don’t just use 10% of our brains. We use 100% of them.

But not all of us are performing and achieving to our highest standards. Find out what blocks you have and work at improving every day.

Myth #5: Believing that smart people have bigger brains

When it comes to size, we’re obsessed with believing that bigger is better.

The simple fact is that a bigger brain has no ultimate bearing or indication on our intelligence.

A very easy way to debunk this myth is to look at the animal kingdom. A cow has a bigger brain than a chimpanzee. But is it smarter?

A whale or an elephant have a bigger brain than a human. But are they smarter?

Many neuroscientists now agree that it isn’t size, but the complexity of neural connections that truly determine a brain’s capacity and potential.

To translate this, it’s not size that matters most. It’s how efficiently different parts of your brain communicate with each other.

Lesson:

It’s not how big your brain is that matters most, but how well the different parts communicate.

Train your brain to connect different ideas, senses, intelligences together and keep learning everyday.

Myth #6: Believing women and men have different brains

Of all the myths here, this perhaps is one of the most damaging.

It sets you up to behave according to a preconceived idea of how you should or shouldn’t behave based on your sex.

Let’s start with what is true.

Yes, there are some very very minor anatomical differences between male and female brains.

However, this difference has never been linked to a difference in ability. What we do know, is that any distinction which is created is the by product of our own cultural conditioning.

If there is a difference, or inequality, it is one created by our society.

A common misconception is that women do better when you test them accordingly to emotional intelligence and empathy. The anatomy of the brain runs counter to this however.

The hippocampus, associated with memory, is typically larger in women, while the amygdala, involved in emotion, is larger in men, which is quite contrary to the myth.

Lesson:

Your sex does not determine what you are fated to be good or bad at. It’s often the result of our cultural conditioning.

Reflect on your own gender biases and avoid stereotyping yourself or others based on this.

Myth #7: Believing you know what makes you happy

This probably surprised you a little, didn’t it?

Deep breaths. Allow me to explain:

Advertising

We commonly believe that we know exactly what will make us happy and unhappy.

The truth however is that this isn’t (totally) true. We massively overestimate how happy we think something will make us feel — gifts, promotions, marriages, divorces — you name it.

Even when it comes to money, countless studies have shown that beyond a certain point (around 77,000USD/year), money doesn’t really make us that much happier.

Conversely, the things that we fear and avoid don’t make us as unhappy as we expect.

The commute on a Monday morning is nowhere near as bad as we think, nor is the awkward conversation with an estranged family member or friend.

The most soul crushing tragedies — breakups, losing a loved one — cause us despair and grief, but don’t last as long as we anticipate.

Lesson:

Things are never as bad as they first seem, or as good as they first seem. You’re not that good at predicting how you will feel, or felt about the future or the past.

Myth #8: Believing you lose mental power over time

When we’re young, it’s easier to take risks and try new things to some degree. But as we age, we seek our comfort and routines.

Until eventually, those same patterns and routines become shackles.

Maybe that’s why you haven’t:

  • Stuck to that workout or yoga routine you want to get better at.
  • Finished the book you say you want to write and publish.
  • Started that business idea you’re thinking and talking about so often.

Many people fall into this trap of believing they “lose it” over time, and this mental error quickly sends them on a downward spiral of stagnation and mediocrity.

I want you to realize something:

Your brain and intelligence can get better with age.

So be excited, not demoralized!

It’s well known in business circles for example, that you get better as an entrepreneur as you age. The same is true in so many other fields too.

Of course there are some cognitive skills which decline in efficiency as you age – learning new languages, memorising a list of random words, counting backward by sevens.

But who cares?

Vocabulary, judgement of character, social wisdom, conflict resolution, emotional regulation and finding purpose – these are all skills that matter, which we are proven to get better at over time.

Sounds exciting, doesn’t it?

Well, let me take you a step further.

Not only can you get smarter over time, you can even continue (literally) growing your brain.

A brain which is active, for example learning new languages, trying new skills and hobbies, develops a richer connected network of brain cells. Taking it further, this “brain growth” also helps to prevent dementia and other diseases.

So no, it is not true that your mental decline is inevitable. Quite the opposite, the effects can be stopped and even reversed through mental exercise. The best part is you don’t even need to do it for that long.

In a study of more than 3,000 people aged 65 and over, just 10 hours training over several weeks in memory, problem-solving and decision-making resulted in significant and prolonged increases in cognitive ability.

Lesson:

Spend 10 to 15 minutes daily working on your memory, problem solving and decision making.

One of my favourites (which is a lot of fun) is to play Chess puzzles for free on lichess.com.

Myth #9: Believing there are 5 senses & one measure of intelligence

What if I told you that you don’t have just 5 senses? And school only tested you on one measure of intelligence?

Would you believe me?

Advertising

A commonly held belief that most of us have is that we have 5 senses and one type of intelligence.

It’s not your fault either, our entire paradigm of education only ever tests us on one “type” of intelligence” – via exams and essays. When in actuality, there are eight types of intelligence.

Just think:

There’s probably a type of intelligence that you may be a genius in, that you were never even tested on in school.

A comforting thought for those of us who didn’t ace every math or english test.

Additionally, there are not just 5 senses. But six more:

  1. Equilibrioception: A sense of balance, otherwise known as your internal GPS.
  2. Proprioception: A sense of where your body parts are and what they’re doing.
  3. Nociception: A sense of pain.
  4. Thermo(re)ception: A sense of temperature.
  5. Chronoception: A sense of the passage of time.
  6. Interoception: A sense of your internal needs, like hunger, thirst, needing to use the bathroom, etc.

The most fascinating part is that when we contrast this to other species, there are so many more senses we don’t have. Bats and dolphins can use sonar to find prey, sharks can sense electrical fields, and birds and turtles can even orient to the earth’s magnetic fields.

If anything, this displays how much more there is to know that we cannot even comprehend.

Here’s a philosophical quote that builds on this idea, from one of my favourite wise men, Sadhguru Jaggi Vasudev:

“You are seeking the infinite through the physical. Can the physical ever become infinite? The physical is finite, always within a finite boundary, it can never be infinite. It’s like you are riding a bullock cart but your destination is the moon, and somebody is saying buy yourself a new whip. If your destination is the moon, you need an appropriate vehicle. So through the physical if you are seeking the infinite, there will only be frustration.”

Lesson:

You are more intelligent than you may know. You have more senses than you know. But equally, there are vast oceans of unknowns too that you can’t comprehend.

Keep expanding and learning constantly, don’t rest on the knowledge you have. Strive to unlearn and learn simultaneously. Stay humble.

Myth #10: Believing your memories are accurate

This last myth is quite mind blowing.

What if I told you that your memories are not real? And that each time you access them, the more distorted they become?

If we just take a glance of the various types of biases that the brain has – there are at least 20!

There’re so many different ways in which the brain we have, has small errors or faults built into it.

And here is just one of them:

Every time you access memories, you project your current feelings and mindset onto that memory. As a result, your memory itself changes.

Mind blowing, right?

But how does this help you?

Well each time you look back on an experience, you are changing it. This means you can’t accurately predict or recall how things really were.

Knowing this, how much more important are those seemingly menial things like:

  • Creating a daily journal of what you are thinking, feeling and planning to look back on later.
  • Keeping clear and up to date records of your workout progression.
  • Tracking your to do lists, goals and plans throughly to keep yourself focused.

Lesson:

You aren’t able to recall things as accurately as you might think. So take diligent notes always in everything you do.

From your feelings, hopes and dreams to your day to day budgeting, to-do lists and more. These written records will help you remember things more accurately!

Have you found yourself understand a lot more about your brain? The most popular myths about left brain and right brain are now busted. It’s your turn to really develop your brain’s potential and don’t get restricted by those myths!

12 Best Brain Foods To Help You Focus Like A Laser

Do you ever feel like your brain can function better than it is currently? Have you ever had moments of laser sharp focus and wished they stayed with you forever?

We have all had those moments where we found ourselves being super productive and having lengthened periods of concentration and focused attention, and if there was a way we could make such kind of mental state a permanent state for us, we would definitely go for it.

And while we cannot make the state come back and stick with us forever in just an instant, there is a way we can slowly cultivate it in our lives in the long term.

One of these ways is by being keen on eating brain boosting foods. Some foods enhance the regions of the brain that are linked to concentration, focus, reasoning, thinking abilities, and overall brain health. By eating these foods regularly, you can also improve your brain function and slowly work to a healthy and well performing brain.

Let’s take a closer look at the 12 best brain foods to take to boost your focus and overall mental health.

1. Coffee

Coffee is among the most popular beverages that sharpen your focus and increase productivity. Millions of people across the world rely on it to help them through demanding tasks at work and assignments at school.

The reason why coffee has proven to be effective over the years is due to the two components in it that largely enhance the brain.

These components are antioxidants and caffeine.

Antioxidants help with protecting the brain from common mental health conditions such as stroke, Parkinson’s disease, cognitive decline and Alzheimer’s disease.[1][2]

Caffeine, on the other hand, is responsible for influencing the brain in various positive ways including blocking out a brain chemical called Adenosine that makes you want to sleep and increasing the levels of serotonin neurotransmitters which in turn boosts your mood, increase your level of alertness and concentration.[3][4][5][6]

However, it is important to note that taking coffee with moderation is the way to make the most of it. If you take more than 4 cups a day, you might be setting yourself up for the nasty side effects that come with it which are restlessness and inability to sleep.[7]

Striking a good balance between coffee and other beverages will help you avoid the chances of experiencing the side effects. You can try drinking coffee only on those days you want to tackle tedious tasks, and only when you are working on them to maximize its effects in your life.

2. Fatty Fish

When the words fatty fish are mentioned, you naturally direct your attention to salmon, pollack, cod, sardines, mackerel and tuna.

These contain omega 3 fatty acids, which are known to help with improving learning abilities and memory, not to mention helping with building nerve and brain cells.[8][9][10][11]

Improved cognitive performance brought about by omega 3 fatty acids can be attributed to the fact that they help increase flow of blood in the brain. [12]

Also, when it comes to general mental health, eating oily or fatty fish helps to delay the mental decline that comes with age, as well as depression and reduce learning problems. [13] [14]

Advertising

Omega 3 has also been associated with the lowering of the protein called Beta-amyloid in the brain that is responsible for forming destructive clamps in people who struggle with Alzheimer’s.[15]

You are encouraged to add fatty fish to your eating plan and consider having it often.

Also, if you would like to obtain omega 3 fatty acids without having to feel like you have to eat fish every time, you can use other alternatives such as walnuts, flaxseeds and avocados. They are also good sources of omega 3.

3. Maca

Maca is a plant from Peru that is grown in Central Andes and has been cultivated a little over 2000 years now. Its scientific name is Lepidium meyenii and is used as a foodstuff as well as a medicinal plant.

It is said to bring about many health benefits including boosting learning abilities and memory, improving mood, increasing energy levels and endurance, improving sexual health in men, and regulating blood pressure.[16]

When it comes to the mental health benefits, Peruvian natives in the Central Andes attribute their children’s good academic performance to regular use of maca.[17]

While there are different varieties of maca, studies have found that the black variety is the one that shows strong effects on mental health improvement, and both hydroalcoholic maca extract and boiled aqueous maca extract have the same effect on the brain.[18]

Scientific studies on maca are still in their infancy and the cause of the effects that it has shown are not yet fully established. However, it is suggested that Macamides, which are maca compounds, might be behind its potency.[19]

You can add maca to your smoothies, energy bars, oatmeal, and any baked foods to enjoy its benefits.

4. Green Tea

Green tea is another known stimulant that helps you remain alert. It contains two compounds that go a long way in influencing the brain.[20]

First, it contains caffeine which accounts for the alertness.

Although coffee contains a much higher quantity of caffeine than green tea, the latter is found suitable to use for those who prefer a well toned effect of caffeine.

Caffeine helps with regulating neurotransmitters like norepinephrine, dopamine and adenosine, as earlier mentioned, that helps with keeping you awake and in good balance in terms of moods and brain function.[21][22]

Second, it contains. L-theanine.

L-theanine is an amino acid that can cross the blood-brain barrier and into the brain which then promotes increase in GABA (Gamma aminobutyric acid) which promotes relaxation.[23][24][25]

It also increases the alpha waves in the brain which are responsible for the calm, conscious and relaxed mental state.

Advertising

When L-theanine and caffeine are combined, they both have a much powerful effect, and this explains why taking green tea for many people has been found more rewarding than coffee.

L-theanine has also been linked to other mental health benefits such as improving memory and protection from mental illnesses like Parkinson’s and Alzheimer’s.[26][27]

Taking green tea in the morning and just before going for a physical exercise helps.

5. Green Leafy Vegetables

Greens are packed with nutrients that enhance the brain in great ways. Broccoli, Swiss chards, kales, dandelion greens, collards and spinach are among the vegetables that have high nutritional value that make them useful for brain health.

Broccoli, for instance, has antioxidants and Vitamin K, among other plant compounds that contribute to better memory, anti-inflammatory effects and brain protection benefits.[28][29][30]

Kale is heavily packed with nutrients like Vitamin A, B6, C, K, potassium, manganese, copper and calcium that promote brain development, slowing cognitive decline caused by age, depression and even various health conditions like Alzheimer’s.[31][32][33][34]

Generally, leafy vegetables contain a variety of nutrients including vitamins, minerals and antioxidants that elevate various regions of the brain that are associated with memory, alertness, processing of information and overall brain health.

Working with delicious green smoothies and recipes that use a lot of greens will largely contribute to a better functioning brain.

6. Dark Chocolate

Other than the sweet taste, dark chocolate also boosts your brain.

It contains three compounds that make this possible, which are, caffeine, antioxidants and flavonoids.

Since we have already seen that caffeine offers the stimulating effects that keep you alert and antioxidants help with keeping mental illnesses and cognitive decline at bay, let’s take a closer look at flavonoids.

Flavonoids are micronutrients that reduce neuroinflammation, protect neurons from neurotoxin-based injury and are potentially effective in enhancing learning, cognitive performance and memory.[35][36] [37]

Studies have also revealed that dark chocolate brings about a positive feeling.[38]

Dark chocolate contains cacao, which is often referred to as cocoa. Aiming to eat dark chocolate that carries more than 70% cocoa ensures that you get optimal benefits from it.

7. Nuts

Nuts such as walnuts, cashew nuts, hazelnuts, pecans, to name a few, contain several brain improving nutrients.

They come with the popular antioxidant, Vitamin E, that protects the brain cells and cell membranes from oxidative stress and damage by free radicals.[39][40][41]

Advertising

Long term consumption of nuts has contributed to a sharper memory, better academic performance and lower risks of getting mental illnesses too.[42][43]

They have also shown abilities to improve the factors that account for good heart and brain health.

All nuts have their nutritional benefits but you are encouraged to eat walnuts more as they have a much higher value due to the presence of high levels of alpha-linolenic acid, which is a type of omega 3 fatty acid.

8. Avocado

Avocado is surprisingly a berry, and it is referred to as a big berry.

Although it hasn’t been fully studied yet, it is believed to carry vitamins B5, B6, C, E and K. Also, it comes with folate and potassium.

There are also low amounts of other nutrients including copper, phosphorus, magnesium, zinc, manganese, and iron that are present in it.

Moreover, it contains a monounsaturated fatty acid called Oleic acid, which is part of what makes olive oil good to use. This fatty acid is known to have many benefits, some of which are lowering inflammation, and brain development.[44]

Adding it to your recipes or making smoothies, and regularly eating it together with your favorite fruits will help you take advantage of its nutritional value.

9. Eggs

There are 4 micronutrients in eggs that give the brain an extra edge, folate, choline, vitamin B6 and B12.

Folate helps to slow down the mental decline that comes with age.[45]

Choline is used by the body to increases the levels of a neurotransmitter known as Acetylcholine that is associated with memory, mental function and moods.[46][47][48]

The yolk of an egg is where the choline micronutrient is in high quantities, and people who desire to increase their choline levels in the body are encouraged to focus on that part.

Vitamin B6 brings down the high levels of an amino acid called Homocysteine in the blood that causes depression and other psychiatric issues.

It also plays the role of increasing the levels of neurotransmitters like GABA (Gamma-aminobutyric acid), serotonin and dopamine, which modulate emotions.

Vitamin B12 also helps with reducing the symptoms of depression as well as preventing losing neurons that in turn cause poor memory.[49]

10. Citrus Fruits

Citrus fruits are categorized into lemons (which include meyer lemons and eureka lemons), sweet oranges (which include blood orange, Valencia, cara cara and navel), limes (which include kaffir, Persian and key lime), mandarin (which include tangelo, tangor, satsuma and clementine), grapefruit (which include ruby red, white and oroblanco) and others such as yuzu, sudachi, citron and pomelos.

Advertising

They have the B vitamins as well as Vitamin C, copper, phosphorus, potassium, and magnesium. There are also lots of varieties of carotenoids, essential oils and flavonoids present in citrus fruits.

On top of that, they are also known to possess antioxidating and anti-inflammatory effects.

Vitamin C reduces inflammation, offers protection to neurons from oxidative stress, modulates neurotransmission (communication between neurons), and also influences neuronal development.[50]

Some of the minerals in citrus fruits have been found to reduce symptoms of depression in women.[51]

They have also been associated with influencing communication through the nerves and regulating neurotransmitters.[52]

The flavanoids protect the nervous system from damage through the anti-inflammatory effects they have. And this helps to keep mental health conditions like Parkinson’s and Alzheimer’s away.[53][54]

11. Turmeric

Turmeric is a spice we add to our foods to make it delicious that also does a bit of magic to our brains.

Curcumin is a primary active component in turmeric that easily passes the blood brain barrier.

It brings about anti-inflammatory and antioxidant effects that drag along the benefits of improved memory, promoting growth of new brain cells and managing moods.[55][56]

Also, it has shown potential to handle Alzheimer’s diseases, although it has not been fully confirmed as reliable treatment.[57][58]

12. Beetroots

Beetroots which are commonly referred to as beets are also great brain enhancers.

They can help prevent mental decline that is associated with poor blood flow to the brain. They have nitrates that encourage blood vessel dilation that then allow more blood and oxygen to flow to the brain, and thus enhance its functions.[59]

More specifically, they improve flow of blood to a part of the brain known as the frontal lobe.

This is a region that is linked to higher cognitive functions including concentration and attention, problem solving, reasoning and judgment, motor function, impulse control, memory, social interaction and emotions.

Conclusion

There you go, the best brain foods that you should make your closest friends.

You should aim to have them often if you would like to see an improvement in your brain function in the coming months. Looking for recipes that use the foods mentioned above as ingredients and adding them to your recipe book is a good place to start.
