Learn About Building Better Instincts and Decision-Making

Understanding How Your Brain Makes Decisions

Your brain processes thousands of pieces of information every day, and most decisions happen faster than you realize. When you decide what to eat for breakfast or whether to take a different route home, your brain is drawing on patterns it has learned over time. These patterns form the foundation of what we call intuition or instinct.

Research in cognitive psychology shows that your brain has two main decision-making systems. The first system works automatically and quickly, relying on mental shortcuts called heuristics. These are rules of thumb your brain uses to make fast decisions without much conscious effort. For example, if you've had good experiences with a particular brand in the past, you might automatically choose it again without carefully reviewing all the options. The second system is slower and more deliberate. It requires focused attention and logical thinking, like when you're learning something new or solving a complex problem.

Both systems are valuable, but they work differently. Your automatic system evolved to keep you safe and help you function in a world with too much information to process consciously. However, this speed comes with a cost. Your brain sometimes takes shortcuts that lead to mistakes or biased thinking. For instance, if you see a news story about a plane crash, you might overestimate how dangerous flying is because that dramatic example is easy to remember. This mental error is called the availability heuristic.

Understanding these two systems helps explain why you sometimes make decisions you later regret, and why other decisions feel effortlessly correct. Your automatic system is responsible for building intuition, which develops through repeated experience. When a musician plays a complex piece without thinking about each note, or when an experienced driver responds instantly to a hazard, they are using intuitive knowledge built through thousands of hours of practice. The key insight is that good intuition comes from genuine experience, not from guessing or wishful thinking.

Practical Takeaway: Notice which decisions you make automatically and which ones require thought. For important choices, try pausing to engage your deliberate thinking system rather than relying solely on quick impressions.

How Experience Builds Better Instincts

Intuition is not magic or a mysterious sixth sense. It is the result of your brain recognizing patterns based on what you have encountered before. When you develop stronger instincts in any area, you are training your brain to spot relevant patterns quickly and accurately. A chess grandmaster can glance at a board and immediately sense which moves are strong or weak. A doctor with decades of experience can often diagnose a condition quickly because they have seen many similar cases. A seasoned investor might sense when a market is overheated. All of these examples show intuition that comes directly from repeated, focused experience.

The quality of your experience matters significantly. Simply doing something many times does not guarantee that your instincts will improve. For example, a driver who has driven the same route for twenty years might not develop better instincts about unfamiliar roads. What matters is deliberate practice—experience where you are actively trying to improve, receiving feedback, and adjusting your approach. Studies of expert performers across many fields show this pattern consistently. Musicians who practice focused on specific difficult passages improve more than those who simply play through pieces. Athletes who practice with clear goals and coaching develop better instincts than those who merely go through the motions.

Another important factor is diversity of experience. If you only encounter one type of situation repeatedly, your instincts will be tailored to that narrow context. However, if you encounter many variations and learn how they differ, your brain builds more flexible and accurate patterns. Consider someone learning to evaluate people's trustworthiness. If they only interact with people from similar backgrounds, their instincts about what signals indicate honesty might not transfer to different cultural contexts where body language and communication styles vary. Broader experience helps your brain distinguish between true patterns and coincidences.

Feedback is another crucial element. Your instincts improve most when you learn the results of your decisions. If you make a judgment and never discover whether it was correct, your brain cannot update its pattern recognition. This is why some professions—like medicine or weather forecasting—develop stronger intuitive expertise than others. Doctors learn quickly whether their diagnoses were right. Weather forecasters receive constant feedback about their predictions. In contrast, some fields with delayed or unclear feedback produce weaker intuition, even with significant experience.

Practical Takeaway: To build better instincts in an area you care about, seek out varied experiences, practice with specific goals in mind, find ways to get timely feedback on your decisions, and reflect on what you learn from both successes and mistakes.

Recognizing and Managing Your Mental Biases

Your brain's shortcuts sometimes lead you astray. These mental errors, called cognitive biases, affect everyone. Understanding them is one of the most valuable skills for improving your decision-making. Biases are not character flaws or signs of stupidity. They are built into how human brains work. Even highly educated, intelligent people fall prey to the same biases repeatedly.

One common bias is confirmation bias. This is the tendency to seek out information that supports what you already believe and to overlook information that contradicts it. Imagine you believe that a particular investment strategy works well. When you search for information, you might focus on successful examples and ignore the times it failed. Your brain does this automatically because finding supporting evidence feels good, and contradictory evidence triggers discomfort. This bias can trap you in poor decisions because you never adequately test your beliefs against reality.

Another prevalent bias is the sunk cost fallacy. This occurs when you continue investing time, money, or effort into something because you have already invested so much, even when the rational choice would be to stop. For example, you might continue in a job you dislike because you have already spent five years there, or keep watching a movie you are not enjoying because you have already watched half of it. The time and effort you have already spent are gone regardless of what you do next. Yet your brain treats these past investments as a reason to continue, which leads to poor decisions.

Overconfidence bias causes people to overestimate how much they know and how accurate their judgments are. Studies consistently show that people believe they are better than average at driving, more intelligent than average, and more moral than average. These beliefs cannot all be true simultaneously. This bias is particularly dangerous when making important decisions because it can prevent you from seeking additional information or perspectives. Someone might refuse to research before making a large purchase because they are confident in their initial judgment, even though their confidence is not justified.

Understanding these biases means you can put systems in place to counteract them. To fight confirmation bias, actively seek out perspectives that disagree with yours. To combat the sunk cost fallacy, practice making decisions based on future outcomes, not past investments. To manage overconfidence, build in extra steps for important decisions, like consulting others or researching more than feels necessary. These practices feel slower and less intuitive, but they lead to better outcomes.

Practical Takeaway: Choose one bias that you think affects your decisions most often. Design a specific practice to counteract it—for example, if you tend toward confirmation bias, commit to reading one opposing viewpoint before making important decisions.

The Role of Emotion in Sound Decision-Making

Many people think of emotions and good decision-making as opposites. This view is incomplete and sometimes dangerous. Research shows that emotions are actually essential to making good decisions. People with brain injuries that affect their emotional processing often struggle with basic decision-making, even though their logical thinking ability remains intact. This reveals that emotion and reason are not enemies but partners in sound judgment.

Emotions provide rapid evaluation. When you feel uncomfortable about a business deal, or excited about a person you just met, those feelings contain information your brain has processed. Your emotions draw on past experiences and pattern recognition that might not be conscious. If a deal has characteristics similar to ones you or others have seen go wrong, you might feel uneasy without being able to articulate exactly why. This emotional signal can be valuable, provided you also think through your reasons consciously.

However, emotions can also distort judgment. Strong fear or anger can narrow your thinking and push you toward reactive decisions you later regret. Emotional excitement can lead you to overlook risks. The goal is not to eliminate emotion from decision-making but to balance it with deliberate thought. One useful approach is to notice your emotional reaction, acknowledge it, and then pause before acting. Ask yourself whether the emotion is based on the actual situation in front of you or whether it reflects past experiences, stress, or other factors not relevant to this specific decision.

Different emotions play different roles. Appropriate anxiety about a risky decision can prompt you to research more
