Since users (1) now have a financial incentive and (2) the power to resolve questions, will the number of inaccurately resolved questions increase?

This will be measured by user reputation. Significant downside deviations post pivot would resolve as yes, while no change or an increase would resolve no.

If Manifold changes the resolution mechanism as a result of degradation, this will resolve yes.

If the resolution mechanism is changed prior to pivot this will result in N/A.
