How Aging Changes Financial Decision-Making: Insights From Neuroeconomics
March 25, 2026
One of the most comforting insights from this research is also one of the most important: Good financial planning isn’t just about choosing the right investments — it’s about building a system that still works for you years from now.
None of us experiences life, health, stress, or decision-making in exactly the same way at 70 as we did at 40. And that’s completely normal. The goal of a long-term financial plan is not to expect you to always make perfect decisions on your own. The goal is to make sure you never have to.
Over time, markets will change. Tax laws will change. Technology will change. Even the way we process information changes. What protects you isn’t reacting faster than everyone else — it’s having structure, guardrails, and someone helping you interpret what actually matters and what doesn’t.
We want your financial life to feel organized, understandable, and steady, especially during uncertain moments. When news headlines are loud, emotions are high, or a decision feels overwhelming, that’s exactly when planning should take the pressure off you, not add to it.
Our role is not just managing investments. It’s helping you make thoughtful decisions, avoid costly mistakes, and keep your long-term goals clear and protected.
Because financial confidence isn’t built from predicting the future.
It’s built on the idea that you don’t have to navigate it alone.
Avantis Investors explains how aging influences the financial decisions we make, drawing on insights from neuroeconomics:
- The Brain Behind Financial Decisions: Your financial decisions are guided by three brain systems — one that seeks rewards, one that detects risk, and one that evaluates information and regulates emotions. As these systems change over time, the way we interpret investment opportunities and risks also changes.
- Why Learning from Financial Outcomes Becomes Harder with Age: With age, the brain becomes less precise at learning from feedback. This can make it harder to identify which investments are truly performing well, sometimes leading investors to hold underperforming assets or take risks that no longer fit current conditions.
- Why Regime Changes Are Especially Challenging: Markets constantly evolve due to technology, policy, and economic shifts. Older investors may rely more on past experience, which can make adapting to new market environments or adjusting portfolios more difficult — not because of stubbornness, but because of how the brain processes new information.
- Risk, Time and Trust: What Does — and Doesn’t — Change with Age: Risk tolerance and patience remain relatively stable across adulthood. However, older adults tend to trust others more easily, which is one reason they are more vulnerable to financial scams and fraud.
- A More Nuanced View of Aging and Decision Quality: Aging does not simply reduce decision-making ability. Many older adults compensate with experience, discipline, and stronger emotional regulation, often remaining calmer during market volatility and avoiding emotionally driven mistakes.
- Designing Better Financial Environments for an Aging Population: Simplified financial information, clear comparisons, and visual explanations significantly improve financial decision-making. Structured guidance and organized planning help offset the increased complexity older investors face.
The takeaway isn’t that older adults make worse financial decisions — they simply process financial information differently. Effective financial planning should account for this by providing structure, clarity, and ongoing guidance throughout retirement.
