Pandemic. Conflict. Market crash. Government upheaval. A quick look at recent headlines conveys a sense of instability in the world. However, “volatility” isn’t just a concern for hedge fund managers; it holds crucial significance for our brains as well.
In my new book, The Trick of the Heart, the latest science suggests that the brain operates like a scientist. It constructs hypotheses and frameworks to understand the world, others, and even itself. However, if your brain is busy crafting a framework, it must also recognize when it’s time to adapt. This process involves a network of frontal and subcortical brain regions, with noradrenaline playing a vital role in monitoring how unstable our environment is.
This “volatility tracking” mechanism allows our brains to detect tipping points in the external world and adjust our expectations and hypotheses accordingly. This adaptability becomes crucial when our daily realities shift; as a result, our mental frameworks can become more flexible. This process is entirely adaptive and logical. After all, when circumstances are in flux, we want our minds to adjust as well.
Yet, in a transformative environment, having an open mind can present dangers. For instance, research conducted during the Covid-19 pandemic indicated that unexpected viruses and unprecedented lockdowns led some people to question what constitutes a normal mindset. A study in the US found that as lockdowns intensified across states, unstable thinking surged. Those who began perceiving their surroundings as insecure were more likely to endorse bizarre conspiracies related to the pandemic, such as the belief that vaccines contain mind-controlling microchips or support for political conspiracies like QAnon.
While these ideas may appear ludicrous, this behavior can be understood through the lens of brain function. Our minds need to remain malleable and resilient, adapting their paradigms based on a rapidly changing world. We must be willing to consider perspectives we’ve never previously entertained.
I actually believe that navigating uncertain times isn’t inherently detrimental for us or our brains. After all, unpredictability does not equate to inevitable doom; it simply means we can’t foresee what lies ahead. Historically, many periods of significant progress have emerged during times of upheaval when our familiar realities were disrupted. In the UK, support for women’s suffrage gained momentum after World War I, which also paved the way for a transformative welfare state and the establishment of a second National Health Service.
While I can’t travel back in time to observe the brains of those historical figures, I can imagine those moments of new opportunities functioning just like our minds do today. When our surrounding touchpoints appear unstable, old concepts can be discarded and new ones adopted.
Uncertainty and volatility are distinctly perceived based on how the brain operates. While volatility can induce anxiety, living amidst constant change opens our minds to new possibilities. We must remain alert to those who might exploit our adaptable minds towards extreme or conspiratorial concepts, but we can also embrace a brighter, more optimistic future by steering our cognitive processes toward pivotal changes.
