Thinking in Bets: The Discipline of Rational Decision-Making

In the face of uncertainty, it's easy to fall into the trap of making decisions based on fear or emotion. However, there is a more rational approach to decision-making known as thinking in bets.

What is Thinking in Bets?

Thinking in bets involves viewing decisions as bets with uncertain outcomes. Instead of aiming for certainty, betthinkers focus on maximizing their expected value (EV) by making decisions that have a positive long-term payoff.

The Benefits of Thinking in Bets

The benefits of thinking in bets are numerous:

• Increased Rationality: By removing the pressure to be right, betthinkers can make decisions more objectively.
• Improved Decision-Making: Betthinkers consider all the possible outcomes of a decision and their probabilities, leading to better choices.
• Reduced Stress: Knowing that you're not expected to be right all the time can alleviate anxiety and stress associated with decision-making.

How to Think in Bets

To think in bets, follow these steps:

1. Define Your Goal: What do you want to achieve with this decision?
2. Identify All Possible Outcomes: List all the possible outcomes of your decision, both positive and negative.
3. Estimate the Probabilities: For each outcome, estimate the probability of it occurring.
4. Calculate the Expected Value: Multiply the probability of each outcome by its value.
5. Make a Decision: Choose the decision with the highest expected value.

Stories of Thinking in Bets

Example 1: The Poker Player
A poker player with a pair of aces is facing a bet. By calculating the EV of calling or folding, they determine that calling has a higher EV, even though there's a high chance of losing the hand.

Example 2: The Entrepreneur
An entrepreneur considering starting a new business weighs the potential risk and reward. By understanding the probability of success and the potential profit, they decide to take the leap.

Example 3: The Doctor
A doctor needs to diagnose a patient with a rare disease. By considering the symptoms and probability of each diagnosis, they make an informed decision, even though it may not be the correct one.

Why Thinking in Bets Matters

In an uncertain world, thinking in bets is essential for making sound decisions. It helps individuals and organizations:

• Avoid the Trap of Confirmation Bias: By considering all possible outcomes, betthinkers avoid seeking out information that supports their existing beliefs.
• Understand Risk Tolerance: Betthinking allows individuals to assess their own risk tolerance and make decisions that align with it.
• Make Flexible Plans: By anticipating potential outcomes, betthinkers can create flexible plans that can be adjusted as new information becomes available.
