This document discusses challenges in forecasting for the travel industry and lessons learned from forecasting research. It summarizes that: 1. Both statistical models and human judgment have been unable to fully capture future uncertainty and accurately predict black swan events. 2. Simple statistical models often predict the future better than more complex models, despite fitting past data less accurately. 3. Averaging predictions from multiple individuals generally improves forecasting accuracy over relying on expert judgment alone. Managing complexity through signal detection, contingency planning, and managing black swans is important.
