# Better Decision Making
Decisions are bets on an uncertain future. Even the best decisions can have bad outcomes, and poor decisions can sometimes lead to good results. The key is separating the quality of the decision from the quality of the outcome.
## Core Concept: Thinking in Bets
- Every decision is a bet with limited information.
- Results ≠ Decision Quality.
- Focus on process over outcomes.
## Practical Decision Framework
### 1. Acknowledge Uncertainty
**How to implement:**
- Use probability language: "I'm 70% confident that..."
- Replace "know" with "believe."
- List what information you're missing.
**Example statements:**
- Instead of: "This will work,"
say: "I'm 80% confident this will work because..."
### 2. Separate Decisions from Outcomes
**Process:**
1. Grade the decision at the time it was made.
2. Grade the outcome.
3. Compare and learn.
**Questions to ask:**
- "Given what I knew then..."
- "What information did I have?"
- "What biases might have affected me?"
### 3. Map Possible Futures
**Steps:**
1. List potential outcomes.
2. Assign rough probabilities.
3. Consider secondary effects.
4. Identify key uncertainties.
### 4. Form Decision Groups
**Purpose:**
- Combat bias.
- Get honest feedback.
- Improve decision quality.
**Rules for groups:**
1. Focus on process, not outcomes.
2. Be explicit about confidence levels.
3. Welcome disagreement.
4. Reward honesty over results.
### 5. Better Learning from Experience
**Implementation:**
1. Keep a decision journal.
2. Record confidence levels.
3. Review regularly.
4. Look for patterns.
5. Update beliefs based on new information.
### 6. Handle Uncertainty
**Strategies:**
1. Express probability ranges.
2. Identify key variables.
3. Plan for multiple scenarios.
4. Update beliefs with new data.
5. Stay flexible in execution.
## Practical Tools
### Decision Journal Template
1. Decision:
2. Date:
3. Confidence level (0-100%):
4. Key factors considered:
5. What could prove me wrong:
6. Expected outcomes:
7. Actual outcome (fill later):
8. Lessons learned:
### Confidence Calibration
**Track your predictions:**
- Write down confidence levels.
- Record outcomes.
- Calculate your accuracy.
- Adjust future confidence levels.
### Red Team Exercise
1. Argue against your decision.
2. List reasons you might be wrong.
3. Identify blind spots.
4. Consider the opposite viewpoint.
## Common Pitfalls
### Resulting
**What it is:** Judging decisions by outcomes only.
**Prevention:**
1. Focus on process.
2. Consider alternatives.
3. Document reasoning.
4. Review regardless of outcome.
### Hindsight Bias
**Combat it by:**
1. Writing decisions down.
2. Recording uncertainty.
3. Documenting available information.
4. Reviewing original context.
## Quick Decision Checklist
Before deciding:
1. What's my confidence level?
2. What information am I missing?
3. What could prove me wrong?
4. What are alternative viewpoints?
5. How could this fail?
## Learning Loop
### 1. Before Decision
- Document assumptions.
- State confidence level.
- List key uncertainties.
- Plan feedback triggers.
### 2. During Implementation
- Track new information.
- Update probabilities.
- Stay flexible.
- Document surprises.
### 3. After Outcome
- Review original thinking.
- Identify learning opportunities.
- Update mental models.
- Share insights with the group.
## The Ultimate Goal
Better decisions through:
1. Embracing uncertainty.
2. Using probability thinking.
3. Learning systematically.
4. Updating beliefs.
5. Building better habits.
You can't control outcomes, only the quality of your decisions. Focus on the process, embrace uncertainty, and keep learning.By Eduarda Ferreira
