Why Investing Cannot Behave Like Physics
Marks rejects the idea that economics and markets operate through stable scientific laws. Human feelings alter decisions, so the same apparent cause can produce different outcomes in different circumstances, making dependable mechanical forecasts impossible.

- Similar inputs can produce different market outcomes
- Human emotion changes behavior
- Investment answers are rarely dependable enough to be mechanical
“umnomics is not a science.”
“physics would be much harder if electrons had feelings.”
