- Of course you can measure what the 'distribution' of many events looks like.

- Wouldn't any probabilistic theory fall under this category? It's a reasonable
- physical question to ask "will it be up or down"? but QM doesn't provide
- an answer.
-
- Your and Einstein's contention is that QM doesn't always predict
- even the probabilities, which in some way, are statistically measurable.
-
- When viewed this way, the EPR problem still appears to remain. If only
- textbooks would present it as a real physics problem rather than some
- philosophical mumbo-jumbo.
