When you are afraid, you start going into fight or flight mode. Your body starts prioritising what is needed for immediate survival - screw routine body functions, if you don't make it past the next few moments there won't be a routine to return to. You stop digesting food. Cell repair slows or stops. You stop producing saliva, which is why your mouth goes dry when you're nervous just before making a speech or going into a difficult conversation. Your heart rate and breathing increase to ensure better blood flow. A cocktail of hormones like epinephrine and oxytocin are cued up and produced, which amplifies your body's ability to act (and remarkably, in the case of oxytocin, reminds you to seek help).
Don't be mistaken about what happens when you feel fear. Your body is readying itself to help you face what you fear in the way it knows how.
What causes us to feel fear?
1) Fear occurs to us unconsciously. Do you pause to think, hey, very angry looking snake! Maybe I should be scared. Of course not, it would be too late! Fear becomes much clearer when we examine what happens inside your brain. When you are afraid, the fear/anger/aggression/anxiety centre of your brain - the amygdalas (get used to this name, it's gonna keep popping up) lights up. And we've covered all the changes that happen in your body: your blood pressure, your hormones, your heart-rate. But remember how amygdala is like a train interchange with direct routes to different parts of your brain? There is a direct neural link between our amygdala and your pre-frontal cortex, the rational thinking part of your brain. And if we look closely enough or we think things through, sometimes we realise, argh! it's not an angry snake, it's just a prank toy that your annoying friend had thrown at you. Or if you've handled angry snakes enough times, your amygdala does not light as much. Your blood pressure and your heart rate do not increase as much, you realise what you need to do is to stay calm and slowly back away.
Finally, notice how fear, anger, aggression, and anxiety are processed by the same part of the brain, the amygdala. This is no coincidence. These 4 emotions are closely tied to one another; aggression maybe triggered because one is nervous, angry, or fearful. Being fearful may cause one to react angrily, as a self-defense mechanism. Fear, like all our emotions, happens to us. Mostly, we can't control how it originates. But we can control how it develops by understanding what exactly is causing fear and by choosing the response that dispels it
2) We fear what we are unconfident or uncertain about. Think back on your ancestors doing something they weren't confident or certain off - hunting a massive animal without a weapon, or eating a berry they've never seen before. Doing so would mean a very high chance of seriously harming themselves. Today, after many cycles of evolution, we have been wired based on these experiences.
Think about it. Are you ever fearful of something you've done before, and are good? Brushing your teeth, putting on your clothes, indulging in your favourite hobby (whatever it is)? Of course not. You know you can perform these functions easily. You are confident.
But many of us would have felt fearful and anxious the first time we ventured into something new: using a pair of chopsticks, riding a bicycle, swimming, going on a first date. We were uncertain about these functions, and we were not confident about performing them. However, once we have demonstrated to ourselves that we are able to perform these tasks, we are no longer afraid. The same applies to more challenging tasks. Some of us struggle with: public speaking, starting a business, having a very difficult conversation with the CEO... You are uncertain and unconfident if you can succeed. But once you have proven to yourself you are able to do it, even for the more challenging tasks, you are no longer afraid. People might start off feeling scared about public speaking, but after speech 3797, you're pro The catch, of course, is that sometimes, we are too scared to start.
Even if we were certain of something OR confident about something, many of us will still feel some amount of fear. We might be theoretically certain how we should use a pair of chopsticks, but if we have never succeeded in using them properly, we remain unconfident and will still feel nervous if we had to use them, especially when others are observing. You might also be confident about
3) we fear what is painful. Boxer. climbing 100 flights of stairs or doing 100 burpees. But pain is not just physical but mental. Failure is painful. Being judged is painful.
This is why you procrastinate. You either fear what you have to do bevause you don't know how to do it (you don't fear brushing your teeth for example), or you fear doing something becaue you know it will be effortful
4) we fear what we cannot control

Summary:
- Fear and anxiety (and anger + aggression) are always
About
I've always been fascinated by human thought and behaviour.
People don’t think what they feel
They don’t say what they think
They don’t do what they say
​
Many of life's great triumphs come when we did much more than we thought we could. Yet, our deepest disappointments come because we were too hasty or we simply never dared to try. We can be inspired by thoughts or a fictional character, yet we can be frightened by our imagination and fictionalise fear.
​
Many of life’s most beautiful moments are shared with others, of thoughtful selflessness or unexpected forgiveness. Yet, many sad experiences come from failed interactions, when pride escalated small misunderstandings, when minds refused to be changed, or when we chose to look the other way. We can build lifelong trust with just a handshake, yet a handshake could also mask the first step of a convoluted betrayal.
​
Human thought and behaviour is complex and perplexing. We are influenced by so many factors - from what happened to our ancestors 3 million years ago, to the culture/era we live in, who our parents are, what stimulus we encountered recently, what others are doing, how our experiences shaped our brains and genes, to the type of neurochemical secreted 3 milliseconds ago in our brain. Our thoughts and actions can be deliberately planned or unconsciously performed. Our brains are always changing.
This site aims to provide you with a better understanding of how we think and behave in different conditions, and why. We explore nature and nurture, decisions and impressions, emotions and rationality, thinking and intuition, action and reaction. We combine this understanding with tools and suggestions so we can be better versions of ourselves.

- Why are we more inclined to regularly put in additional effort late, even late into the night, for work, but struggle to find a time to meet our friends?
- Why has racism always been a part of human societies?
- Why are we so prone to becoming polarised by politics?
- Human life is precious - so why are 40% of deaths accelerated by our own actions?
- Why do we find change so difficult? Why do we like to do what others do?
- Why does everything need to marketed before we would adopt it?
- Are we nature or nurture?
- Do we have free will?
I spent thousands of hours reading books and papers, watching university lectures, and listening to interviews & podcasts of scientists around the world. It turns out that there are answers to all the questions above. Not absolutely conclusive, but much more comprehensive then we can imagine.
​
A terrific amount of work,
Yet terrifying little of which has been communicated to everyone else.
​
Why?
​
1. Science is organised by fields. Each field focuses on its own work, but thought and behaviour is the collective amalgamation of all these fields. No one field can adequately explain why a thought or behaviour
2. Some content is difficult to understand. Additionally, scientists write with other members of the scientific community as the target audience, in a language and manner unappealing to many.
3. Because the content from the experts is more difficult, nuanced, and well-presented, popular understanding of human thought and behaviour comes from non-experts: motivational speakers, media personalities, coaches/consultants. Content is (over)simplified, sometimes indiscriminately, leading to seemingly persuasive but inaccurate conclusions.
​
Aknowbrainer was set up to bridge between experts and the wider audience - all of us, for the important questions we face in our daily lives. We work to make sure each article carries scientific backing, presented simply, but without over-simplifcation. We explore findings across different fields of studies, without obsessing over one. And while it would take talent beyond our means to have drier writing than scientists, we do endeavour to provide you with a good read.
