I clicked this because it seemed interesting, but reading the Q&A:
In atypical game we consider, one player offers bets, another decides how to bet, and a third decides the outcome of the bet. We often call the first player Forecaster, the second Skeptic, and the third Reality.
How is this any different from the classical Dutch Book argument, that unless you maintain beliefs as probabilities you will inevitably lose money?
It’s just a different way of arriving at the same conclusions. The whole project is developing game-theoretic proofs for results in probability and finance.
The pitch is, rather than using a Dutch Book argument as a separate singular argument, they make those intuitions central as a mechanism of proof for all of probability (or at least the core of it, thus far).
There’s a Q&A with one of the authors here which explains a little about the purpose of the approach, mainly talks about the new book.
