What do you think about those strategies as macro strategies to help improve value? Yeah, I think that...

In theory, they sound very good because you're in theory not incentivizing the doctors to order more tests and get paid more.

And so in theory, it should promote higher value care.

And there's some evidence that, say, Medicare Advantage HMOs.

do tend to deliver less low-value care than Medicare fee-for-service plans.

They sometimes have better health outcomes.

The problem with a lot of that literature is that there's this underlying selection bias.

So my question to you is, do you think there's going to be a tipping point? And if so, what might it be?
