How to Make Better Decisions

This is about a 3-minute read.

Decision Quality Shapes Your Life

We make thousands of decisions every day. From trivial choices like what to eat for breakfast to life-altering decisions like changing careers or getting married, the quality of these decisions determines the direction of our lives.

Nobel Prize-winning economist Daniel Kahneman's research revealed that human decision-making is not always rational. We are influenced by various cognitive biases, and recognizing them is the first step toward better decisions.

Cognitive Biases That Distort Decision-Making

Confirmation Bias

For example, this is the tendency to seek information that confirms existing beliefs while ignoring contradicting evidence. This bias operates in investment decisions, performance evaluations, medical diagnoses, and countless other situations. Consciously seeking opposing viewpoints and testing your hypotheses is essential.

Pre-mortem analysis improves decision quality. Before executing a decision, ask "If this fails, what would be the cause?" This technique reportedly improves project success rates by about 30%.

Behavioral economics research suggests that important decisions made in the morning are approximately 20% better in quality than those made in the afternoon.

Sunk Cost Effect

This is the tendency to continue irrational decisions because of time or money already invested. The thinking "I've come this far" can escalate losses. Making decisions based on future prospects rather than past costs is the rational approach.

Anchoring Effect

This phenomenon occurs when initial numbers or information disproportionately influence subsequent judgments. The impact is particularly significant in decisions involving numbers, such as price negotiations, salary discussions, and real estate valuations.

Frameworks for Better Decision-Making

1. Assess the Importance of Each Decision

For instance, not every decision deserves the same energy. Devote ample time to decisions with major impact that are difficult to reverse (career changes, home purchases), and make quick decisions on matters with minor impact that are easily reversible (lunch menus, clothing choices).

Amazon founder Jeff Bezos classifies decisions as "one-way doors" and "two-way doors." One-way doors (irreversible decisions) warrant caution, while two-way doors (reversible decisions) should be made swiftly.

2. Expand Your Options

Many people tend to think in binary terms - "do it or don't" - when more options actually exist. The "vanishing options test" described in decision-making books is an effective technique. If all currently considered options disappeared, what would you do instead? This question surfaces overlooked alternatives.

3. Actively Seek Opposing Views

The more confident you are in your judgment, the more important it is to deliberately seek dissenting opinions. Ask trusted people "What's wrong with this decision?" or ask yourself "Why might this judgment be wrong?"

4. Use Emotions as Information

Some argue that decisions should be purely logical, excluding emotions. However, neuroscience research shows that emotions are an essential component of decision-making. Emotions represent intuitive assessments based on past experience and serve as valuable information sources.

The key is not being controlled by emotions but combining them as one input alongside logical analysis. When experiencing strong emotions, it's wise to allow time to pass before making final decisions.

5. Conduct a Premortem

The "premortem" proposed by psychologist Gary Klein involves assuming "this decision has failed" before implementation and then identifying the causes. While normal planning assumes success, the premortem assumes failure, revealing overlooked risks.

Preventing Decision Fatigue

Making too many decisions in a day leads to "decision fatigue," where judgment quality deteriorates. Routinizing unimportant decisions (eating the same breakfast daily, pre-determining clothing patterns) conserves energy for important decisions. (Related books may also help)

Reflecting on Your Decisions

Becoming a better decision-maker requires the habit of reviewing past decisions. Evaluate not just outcomes but the decision-making process itself. A good outcome from a sloppy process may simply be luck. Conversely, a good process can sometimes yield poor results. Over the long term, process quality determines outcome quality. Books on improving decision-making skills can also help sharpen your judgment.
