As in the causal effect happens to cancel out a confounder, or something more fun? Do you have an example?

- astrange 5y agoI was thinking of an air conditioner - a perfect A/C would mean the temperature is flat. Although hmm, I think R^2 is undefined rather than 0 there. But basically, it's a "if you do it right, it'll look like you've done nothing at all" situation.
- Rury 5y agoWhat variables are you correlating in that example? It seems to correlate just fine if your measuring energy inputed to heat the room vs work done by air conditioner.
