Investing According to Your Genes: Unpacking the Link
Financial choices could potentially be influenced by genetic factors, according to a new study.
Got a chunk of change to invest? Where does it go - stocks, bonds, or a safe savings account? You might think your decision hinges on financial knowledge or risk appetite, but a game-changer is brewing in the world of genes!
Research reveals a fascinating connection between genetics and financial decision-making. The catch? A specific gene called 5-HTTLPR, hiding in your DNA, influences your penchant for risk-taking.
This gene controls a neurotransmitter named serotonin, responsible for mood and anxiety levels. Interestingly, people with a specific version of 5-HTTLPR tend to get the jitters before making financial decisions, leading them to cling to safer investments. This isn't mere theory – it's backed by science [1].
In an experiment, researchers found that individuals with a particular genetic makeup held onto 24% more of their investment in cash compared to those sporting a different genetic makeup.
Rethinking Free Will in Finance
We usually picture financial decisions as cold, hard logic ruled by careful analysis and wisdom. But this study challenges that viewpoint. If genes can influence risk-taking, how much control do we truly have over our financial choices [2]?
Brian Knutson, a psychology professor at Stanford, and Camelia Kuhnen, a finance whiz at Northwestern University, have been investigating this genetic connection for years.
Their research revealed that neuroticism, a personality trait associated with anxiety, plays a significant role in investment behavior. Individuals carrying two short versions of the 5-HTTLPR gene exhibited more neuroticism, leading them to shy away from risky investments [1].
In a 2009 study, Kuhnen and Knutson examined the relationship between financial risk-taking and two genes - serotonin and dopamine regulators. Their recent research, published in PLoS ONE, further supports the idea that some folks are genetically predisposed to be more cautious with money [1].
The Science Behind the Anxiety
To validate this, the researchers conducted a study with 60 volunteers from the San Francisco Bay Area. Each participant received $10,000 and was asked to divide it among stocks, bonds, and cash.
The findings were jaw-dropping: Folks with two short 5-HTTLPR alleles, known for triggering higher anxiety, kept significantly more of their funds in cash compared to those with the long allele. Surprisingly, financial literacy, income, and cognitive ability didn't account for these differences. The primary determining factor? Their genes [3].
However, things became even more intriguing when Kuhnen predicted that anxiety-prone individuals would likely react more strongly to financial losses.
But when participants played a game to identify risky choices, both genetic groups reacted similarly to losses. The difference wasn't in processing negative outcomes but in how they anticipated them [3].
Can You Outsmart Your Genetic Programming?
The implications? Your genes may nudge you in a certain direction, but they don't control your destiny. Understanding how your genetics influence financial choices can help you become more aware of your decision-making patterns.
"As long as you understand how it's influencing your behavior, then you have a shot at changing that behavior," says Knutson.
Takeaway? Next time you hesitate before making an investment, reflect on whether you're acting based on logic or if your genetic wiring is pushing you toward caution. Acknowledging these influences could help you make smarter, more balanced financial decisions [3].

[1] Genes exert a meaningful role in shaping investment behavior, including variants like 5-HTTLPR and other genes affecting cognition and personality. These genetic influences interact dynamically with environmental factors, as in upbringing, education, and parental behavior, creating a complex interplay where genetics shape how individuals perceive and respond to financial risks and opportunities.
[2] More importantly, the idea of "genetic nurture" proposes that parents' genetic predispositions can indirectly affect children's financial behaviors by shaping the environment in which they are raised – for instances, through parental involvement in education and resource investment – which influences the development of traits relevant to decision-making and investment tendencies.
[3] Moreover, the 5-HTTLPR gene affects financial decision-making by moderating emotional and risk-related behaviors. However, genetic effects are not deterministic but operate in tandem with environmental influences, highlighting a nuanced interplay between nature and nurture in financial choices.
- The study on genetic predisposition in finance reveals that the 5-HTTLPR gene, which influences mental health through its control of serotonin levels, can affect an individual's inclination towards risk-taking in financial investments.
- Understanding that genetics can sway financial decisions opens up the question of how much free will we actually have in our financial choices. For instance, research has shown that neuroticism, a personality trait associated with anxiety, can impact investment behavior, particularly in individuals carrying two short versions of the 5-HTTLPR gene.
