Despite the surge of automated processes, human involvement still dominates the realm of investing. From a biological perspective, we are rational beings, yet our actions deviate from the normative economic theory. Fama’s efficient market hypothesis, emphasizing that asset prices encapsulate all available information, poses a challenge for investors seeking consistent outperformance due to factors such as collective emotions, beliefs, and aversion to uncertainty.
When confronted with decisions such as investing in a new opportunity, various segments of your brain come into play, each playing a distinct role. The amygdala, a small, almond-shaped structure deep within your brain, acts as the emotional conductor, managing emotions, particularly fear and excitement. It operates like a character in a soap opera, sending signals of excitement or fear when evaluating an investment opportunity, leading to an intriguing internal struggle of emotions.
Your brain isn’t always the rational thinker you hope it to be. It harbors certain tactics, referred to as ‘biases,’ that can veer you off course and inject a bit of eccentricity into your financial decisions. One such tactic is the “confirmation bias,” where your brain actively seeks information that aligns with your existing beliefs while conveniently disregarding anything that challenges them.
Another deceptive bias is the “loss aversion bias,” as if your brain has an alarm system solely for losses. Studies reveal that the pain of losing money can be twice as potent as the joy of gaining the same amount, making you excessively cautious in financial decisions, even when calculated risks could be more advantageous. Picture yourself deciding whether to sell an underperforming stock; your loss aversion bias might compel you to hold onto it for an extended period, hoping against all odds for a miraculous turnaround, despite clear indicators suggesting otherwise.
There have been some prominent studies on individual’s risk preferences and their results seem to suggest that traumatic life events, such as combat experiences or exposure to war have a huge role to play in individual decision making. Even years later, those who have encountered trauma exhibit a lower inclination towards financial risks compared to their non-traumatized counterparts.
Money and emotions share a close connection. The previously mentioned amygdala plays a crucial role in how emotions shape financial decisions. When your investments thrive, your brain releases dopamine, often termed the “feel-good” chemical. This surge of dopamine can make you more open to taking risks, potentially leading to impulsive decisions. Conversely, when facing financial losses, your brain’s stress response can trigger feelings of anxiety, prompting a “fight or flight” reaction. In this state, impulsive, fear-driven decisions are more likely, which may not align with your long-term financial interests. Grasping this emotional rollercoaster is vital; it’s akin to having a weather forecast for your financial journey. Armed with this knowledge, you can better anticipate emotional fluctuations and make more reasoned decisions.
Various motivations drive individuals to adopt a high-risk, short-term gains strategy in investing. It can be a logically sound choice when presented with opportunities in highly volatile environments, acknowledging that these opportunities are transient.
Some investors opt for opportunistic gains, engaging in repeated high-risk behavior. The allure of high-stakes situations lies in the adrenaline rush during uncertainty and the release of dopamine when such gambles prove successful. This mechanism mirrors the appeal and addictiveness seen in games of chance, tied to the fundamental reward learning mechanism of dopaminergic neurons. Winning an uncertain gamble is perceived as more rewarding, with dopaminergic neurons exhibiting prolonged activity. However, those who prefer certainty may find such games stressful, reflecting their aversion to compulsive gambling. Genetic predispositions related to dopamine receptors in the ventral striatum also play a role.
Nassim Nicholas Taleb wrote in his book Fooled by Randomness “Lucky fools do not bear the slightest suspicion that they may be lucky fools — by definition, they do not know that they belong to such category. They will act as if they deserved the money. Their strings of successes will inject them with so much serotonin (or some similar substance) that they will even fool themselves about their ability to outperform markets (our hormonal system does not know whether our successes depend on randomness),” Mr. Taleb noted an interesting aspect of investing and finance: there are individuals who make significant gains from their investments without a clear understanding of the underlying reasons for their success. Consequently, these individuals often risk and lose their entire gains in speculative ventures, as they lack the insight into the factors that initially contributed to their financial success.
The phenomenon of the lucky fool syndrome is triggered by the self-attribution bias, wherein individuals tend to claim full credit for positive outcomes while readily assigning blame to external factors when faced with setbacks. Compounded by the challenge of distinguishing between skill and luck, this bias exposes individuals to the pitfalls of the lucky fool syndrome. A 2013 study by researchers Arvid Hoffmann and Thomas Post revealed that this bias can lead investors to make repeated mistakes by attributing poor returns to external factors beyond their control. Furthermore, the study highlighted that neglecting the role of luck makes individuals oblivious to detrimental investment behaviors like overtrading and underdiversification.
Acknowledging these challenges, individuals face a choice: either persist in the illusion of expertise, buoyed by serotonin-induced confidence, and endure the associated consequences, or confront and challenge their biases. Although making the right choice is not without difficulty, it is achievable. The first step involves gaining a clearer understanding of the distinction between skill and luck.
The propensity to succumb to games of chance is influenced by trait impulsivity, indicating the ease with which one gives in to temptation. This trait correlates with functional coordination between the subcortical reward center (ventral striatum) and the prefrontal executive control regions. Individuals with low self-control and heightened reward sensitivity are more prone to enjoy and succumb to gambling, as it induces a natural high through the release of dopamine.
Decision-making regarding risky behavior is intricate and can be a result of careful deliberation, considering pros and cons, or impulsive actions driven by subjective value responses. Time pressure tends to lead to riskier decisions, and risk aversion can vary across different domains. Neuroscientific studies show that a network of brain areas, including the insular cortex and anterior cingulate cortex, represents the subjective value of risk. This network engages in a dialogue, ultimately determining whether to approach or avoid the risky option based on the relative signal strength in the value network compared to the risk network.
Your financial decisions carry repercussions not only for your life but also for your relationships, particularly if you share financial matters with a partner. Disagreements about money are commonplace among couples and can be a significant source of stress. Understanding how your brain influences your financial behavior aids in better communication with your partner and in making joint decisions that benefit both of you. It’s akin to having a playbook for teamwork and collaboration in the financial game of life.
The allure of attributing investment success solely to skill can be enticing, leading individuals to believe that intelligence dictates investment returns. This notion tends to create a self-confirming cycle where perceived intelligence validates investment success, perpetuating the cycle with each subsequent triumph. Breaking free from this cycle requires a critical evaluation of the relationship between intelligence and investment outcomes, ultimately challenging the ingrained biases that may lead to the lucky fool syndrome.
You can exercise better control over your financial decisions. You can train your brain to make better financial decisions, much like any other skill. Increasing awareness of your biases and emotions is the initial step. For instance, practicing mindfulness can assist in remaining calm and making more rational choices when facing financial stress. It’s analogous to a mental workout that fortifies your decision-making muscle. Education serves as another potent tool in your financial arsenal. Acquiring knowledge about personal finance and investing can furnish you with the insight and confidence to make better decisions. With a solid understanding of the financial landscape, you are less likely to fall victim to financial scams or make impulsive choices.
Your brain is not merely a stage for emotions and biases; it also functions as a decision-making apparatus. However, like any machinery, it can experience fatigue. Decision fatigue is a tangible phenomenon. Ponder making choices throughout the day; it can deplete your cognitive resources, rendering you more susceptible to impulsive decisions or opting for the easiest choice, which may not always be the best financial decision. Recognizing this can guide you in making more sound decisions. You can prioritize significant financial choices earlier in the day when your decision-making abilities are at their peak. Moreover, automating routine decisions can alleviate the burden on your brain, freeing up mental resources for more critical matters. Money is not a solitary endeavor; it is a collaborative effort.
