What we covered

Have you ever wondered why some people are natural savers while others tend to be more impulsive with their finances? The truth is, our brains play a significant role in shaping our relationship with money. Biological factors can influence financial decision-making in ways that we might not even realize. By understanding the underlying biology, we can gain valuable insights to make more informed choices in managing our finances.

The Role of the Brain

Our brains are complex organs that govern every aspect of our lives, including how we handle money. In particular, the prefrontal cortex and the limbic system are two key areas that impact financial decision-making.

The Prefrontal Cortex

The prefrontal cortex is responsible for executive functions such as decision-making, planning, and impulse control. Individuals with a well-developed prefrontal cortex tend to make more rational and calculated financial decisions. On the other hand, those with a less active prefrontal cortex may be more prone to impulsive spending and risky investments.

The Limbic System

The limbic system, which includes the amygdala and the hippocampus, is involved in regulating emotions and processing rewards. When it comes to money, the limbic system can drive our desire for instant gratification and impulsive spending. Additionally, heightened emotional responses to financial gains or losses can influence our decision-making.

Neurotransmitters and Financial Behavior

Neurotransmitters, the chemical messengers in our brains, also play a role in shaping our financial behavior. Two neurotransmitters in particular, dopamine and serotonin, have been linked to financial decision-making.


Dopamine is associated with the brain's reward system and motivates us to seek out pleasure and rewards. When we experience financial gains, dopamine levels rise, reinforcing our desire for more rewards. This can lead to risk-taking behavior in the pursuit of financial gain.


Serotonin, known as the "feel-good" neurotransmitter, influences our mood and social behavior. Low levels of serotonin have been linked to impulsive and risky decision-making, which can impact financial choices. Furthermore, fluctuations in serotonin levels can affect our tolerance for financial risk.

How to Make More Informed Financial Choices

Understanding the biological factors that influence our relationship with money can provide valuable insights for making more informed financial decisions. Here are some strategies to consider:

  1. Self-awareness: Take the time to reflect on your own financial behaviors and identify any patterns influenced by your brain's biology.

  2. Mindfulness: Practicing mindfulness can help regulate emotional responses to financial decisions, reducing impulsive behavior driven by the limbic system.

  3. Educational Resources: Utilize digital group sessions and content about mental health and financial well-being provided by October to gain a deeper understanding of the psychological and biological factors affecting financial decision-making.

  4. Assessments: Take advantage of assessments offered by October to gain insights into your financial decision-making tendencies and identify areas for improvement.

By recognizing the impact of our brain's biology on financial decision-making, we can take proactive steps to manage our finances more effectively. Ultimately, by understanding and leveraging the interplay of biological and psychological factors, we can make wiser choices and cultivate a healthier relationship with money.

Remember, the next time you're faced with a financial decision, consider the biological factors at play and strive to make choices that align with your long-term financial well-being.
