Well, who knows. You may be deriving money from a different correlation than what you thought. In other words, the cause of money-generation may not be the correlation you thought it is.

For example, you may be making money from your customers' lack of understanding of correlation and causation. You may convince your customers that your product leads to revenues for them when it doesn't. And now the money you derive may be correlated with the strength of their beliefs in your product being correlated to their revenues, but not with your product actually being correlated to their revenues.

I must remind myself to not try and be subtle here on HN. The true cause(s) of any effect can never be determined through observation (this is Hume’s problem of induction).

When dealing with causation there is no way around the step of having to propose a causative model that you believe to be true - the point I was trying to make is there is nothing better than making money to convince people that their own model is the correct one. Making money does not mean the model is correct, just that the person making money will believe it to be correct.
