How Outcome Bias Is Quietly Sabotaging Kenyan Investors

"Past performance is not a guarantee of future results." You've likely encountered this phrase when reviewing investment disclaimers. While it serves as a cautionary reminder to avoid relying solely on historical success, many people still fall into the trap of basing decisions on past outcomes. Why? Because of our outcome bias—a psychological phenomenon that plays a significant role in shaping our financial choices.

What is an Outcome Bias?

The Outcome bias occurs when people judge the quality of a decision based on its outcome, rather than the process or reasoning that led to it. Outcome bias focuses entirely on the result, ignoring the circumstances or factors that contributed to it.

For instance:

An investor may decide to invest into real estate after hearing about a friend’ high returns, without considering critical factors such as market conditions or interest rates at the time.

Outcome bias often blinds us to the risks, nuances, and context of a decision, leading us to make poorly informed financial choices.

Why Does Outcome Bias Influence Financial Choices?

Overemphasis on Success Stories
Success stories are compelling. When we hear about someone making a killing in the stock market or through a business venture, we often focus on their result, not the effort, luck, or timing that went into it. This can lead to unrealistic expectations and risky decisions.
Fear of Missing Out (FOMO)
Outcome bias feeds into FOMO, making people feel pressured to replicate others’ successes. This urgency often results in rushed, poorly considered decisions.
Simplifying Complexity
Financial decisions are complex, involving numerous variables. Outcome bias allows us to simplify this complexity by focusing on a single indicator—success—rather than the broader picture.
Cultural Pressures
In business and investing, there’s often a zero-sum mentality where people are either "winning" or "losing." Outcome bias reinforces this mindset, prioritizing short-term success over long-term strategy or ethical considerations.

How to Break Free from Outcome Bias

To make better financial decisions, it’s crucial to recognize and counteract outcome bias.

Here’s how:

Focus on the Process, Not Just the Result
Analyze the factors that led to a successful outcome, not just the outcome itself. What risks were taken? Were external conditions favorable?
Do Your Research
Before making a decision, gather as much information as possible. Don’t rely on someone else’s success story.
Diversify Your Perspective
Seek opinions from multiple sources and consider alternative scenarios. This reduces the risk of being swayed by a single outcome.
Set Rational Expectations
Understand that success often involves a mix of skill, timing, and luck. Not all opportunities can or should be replicated.
Develop a Long-Term View
Prioritize strategies that align with your goals and risk tolerance over short-term wins.

The Bottom Line

Outcome bias can cloud our judgment, making us overly reliant on past results while ignoring the broader context. By recognizing this bias, we can approach financial decisions with greater clarity and discipline, ensuring they are informed by thoughtful analysis rather than a narrow focus on results.
