Asteroid is discovered in deep space heading for Earth. Astronomers watch the asteroid approach Earth. Asteroid hits New York City. Millions die. Astronomers and media report:

"Asteroid from deep space kills millions. Asteroid causes death of millions."

No experiment is possible. Causation is clear.

I'm sorry to be seeming to make a straw man, but do you actually in sober thought think that economics is as well-understood as physics?

Did you just post a rebutal to your original comment calling for 'experiments'? If economics is as mysterious as you say, how can you design experiments that produce verifiable and reproducible results?

Physics has had a lot of predictive power: economics hasn't. "Asteroids are incredibly powerful" is a physical statement, and a physical statement of causation that you can only make because physics is better-understood.

With exceptions, physical statements have predictive power. With exceptions, economic statements don't. So that's why I say that causality in economics is not generally understood.
