Why does my body react with fear on a suspension bridge even when I know it’s safe?
Imagine this. You are about to walk over a high suspension bridge. You know that the engineering is very good. Thousands of people walk over the bridge every day. But as you step out above the water, your palms start to get sweaty, your heart races, and suddenly you're wondering if a gust of wind might blow you off the side or if the railing will break if you lean on it. Perhaps a freak earthquake is about to hit and the whole bridge will collapse in seconds. You could, of course, turn back, but what if people laugh at you? What if you trip? The only thing your body seems to know is that you aren't safe, despite all your higher logic stating that you are safe. Now, those aren't just random nerves, they are a biological survival mechanism.
Dating back millions of years, fear was our ever-present companion and has been hardwired into our brains to keep us safe. Safe from harm. Whether you are standing in front of a crowd, facing a risky career move, or deciding whether to speak your mind in a tough conversation, that anxiety has been placed there to help save your life. But here lies the problem. Whilst fear was incredibly useful for our caveman ancestors, facing actual life or death situations in the modern world is less about running from lions and more about navigating. complex social, emotional, and personal challenges, yet fear will still operate in much the same way. It can sometimes be a bit like using a fire alarm to alert you to a burnt piece of toast.
The reaction is disproportionate to the actual danger. In this episode, we're going to be exploring the neuroscience behind fear, what's going on in the brain when you feel it, how does this impact our thoughts and behaviors, and then we're going to have a bit of a tour of the four main fears in life that hold us back. Of trauma in changing our brain circuitry. And then I want to look at some more extreme cases. In the same way that anybody can learn about productivity advice by looking at someone with ADHD, I want to look at generalized anxiety disorder and strategies for how to deal with fear that can help all of us. Also look into borderline personality disorder, narcissistic personality disorder, and lastly ADHD, which you might be surprised to learn has.
Quite a lot of fear components within it. The lessons we will cover will not only be useful for individuals who specifically suffer from these problems, you don't need to have borderline disorder to have any fear of abandonment, and we all have an ego we want to protect without actually being narcissists. So learning strategies that these individuals can follow to help with specific flavors of their own fears and anxiety can help us all understand. And some of the science behind the emotions of fear and help us master our own minds. So, hello and welcome to the Growth Mindset Psychology podcast with me, Sam Webster Harris. As always, diving into the science of self-improvement and the philosophy of living a life well-lived, which does mean learning about our fears and how to confront them.
So there's a lot coming up, so please stay tuned for after the break.
How does the amygdala trigger the threat response before the rational brain can react?
To understand why fear holds us back, we first need to explore what happens when fear kicks in. It's not just a mental state. Fear is a full-body experience powered by very old neural circuits. And the process starts deep within the brain, particularly in a small almond-shaped structure called the amygdala or amygdala, depending on what you are taught. Don't hate me if I always use it. Amygdala, but it's the one I'm going with. And you can think of it as your internal security guard in some way. Its job is to scan your environment for threats, assess potential danger, and hit the panic button before you have even consciously realized there is something to be afraid of. And we'll go through a quick tour of the brain regions that collaborate to produce the overwhelming sense of dread you might feel when you face fear or help break.
Regulate the initial triggers to keep us in check. As I've said, we start with the amygdala that processes information within milliseconds to start triggering the fight or flight response, our survival mechanism to get our body ready to confront danger or run from it.
