(is Y due to X? / process tracing / causal attribution)
arxiv.org/abs/1907.00399
Highlights:
1/n
* That's a harder question and answer usually not identified by experimental data
* But don't obsess about identification: you can learn lots even if estimands are not identified
But:
1 Getting arbitrarily "close" to a causal process does not render causal effects observable
2 Process data better for disconfirming causal relations than for confirming them
4. Understanding conditional fx can tighten bounds more than knowledge of mediation
Reminder for me how much to learn working with great people outside your discipline
