The DAG and the DAG for Directed Causality

The DAG gets informed by the experiments that you already have and basically people's intuition for the business. So if I want to get that in, I'm going to say that prices cause your likelihood to use our product. That's a statement about causality. And this is a statement about a part of a DAG. If someone else came back to me and they said, actually, your use of the ride causes the price. That would be a different DAG. But yeah, so the DAG rules out certain models that you'd like to be able to use. Those feedback loops are just really, really hard to estimate.
