Bias and Fairness
What constitutes a biased wheel, how it is detected, and what modern compliance looks like.
A biased wheel is one that deviates statistically from its expected uniform distribution beyond what chance alone produces. Classical biases came from mechanical wear — loose frets, tilted tables, imperfect pocket depth. Modern compliance eliminates most of them; but testing and rotation remain standard.
Scholars of the wheel study published data and, where possible, observe in person. A true bias detection requires tens of thousands of spins. Most claimed biases in private settings are artifacts of small samples.
Key takeaways
- True bias requires very large samples to prove.
- Modern compliance addresses classical mechanical biases.
- Skepticism is the scholar's default.
