Risk vs Reward
Every decision involves balancing potential downside against potential upside. Understanding the relationship between risk and reward — and the psychological biases that distort our perception of both — is essential for making better decisions.
Key Differences
| Dimension | Risk | Reward |
|---|---|---|
| Definition | The probability and magnitude of negative outcomes | The probability and magnitude of positive outcomes |
| Psychology | Loss aversion makes risks feel ~2x larger than equivalent rewards | Optimism bias makes rewards feel more likely than they are |
| Time horizon | Often front-loaded — you bear risk immediately | Often back-loaded — rewards accumulate over time |
| Asymmetry | Can be catastrophic and irreversible (ruin risk) | Typically capped or diminishing returns |
| Relationship | Higher risk doesn't always mean higher reward | The best opportunities are asymmetric — limited downside, uncapped upside |
When to use Risk
- When the downside could be catastrophic or irreversible — never risk ruin
- When you need to stress-test a plan by asking 'what's the worst that could happen?'
- When building portfolio diversification or redundancy
When to use Reward
- When evaluating opportunities with asymmetric upside — limited risk, uncapped reward
- When the cost of inaction exceeds the cost of getting it wrong
- When you've verified the risk is survivable and the reward compounds over time
Frequently Asked Questions
What is the relationship between risk and reward?
In general, higher potential rewards require accepting higher risk. However, the best decisions involve finding asymmetric opportunities where the potential reward far exceeds the risk. Warren Buffett's approach — 'never lose money' — emphasises that avoiding catastrophic downside matters more than maximising upside.
What is loss aversion?
Loss aversion is the psychological finding that losses feel roughly twice as painful as equivalent gains feel pleasurable. Discovered by Kahneman and Tversky, it explains why people are often irrationally risk-averse — they overweight potential losses relative to potential gains.
