Episode notes
Beware The Planning Fallacy
- Cognitive biases like the planning fallacy make us wildly optimistic about timelines and abilities.
- Use the outside view to anchor expectations and avoid predictable disappointment.
Set Kill Criteria Before Trouble
- Establish kill criteria ahead of time to prevent sunk-cost driven decisions during injury or setbacks.
- Use clear thresholds (e.g., pain >3/10 for 3 days) to trigger plan changes and protect long-term progress.
Progress Isn't Predictable
- Training gains are not linear and prediction of improvement is unreliable even for experienced coaches.
- Biological filters and life factors create wide individual variability in adaptation.
