Lack of correlation, wtvanfest. Important word! Lack of correlation is evidence of lack of causation. It isn't absolute proof but it is good evidence. After all, "lack of correlation is evidence of lack of causation" is the contrapositive(ish) of "Causation is evidence of correlation". If that's not true then all hope is lost of ever learning anything.

Sorry, but that's exactly the sort of thoughtless repetition I'm talking about. You're in such a hurry to chant the mantra and wave your scienciness around you didn't even take the time to notice it was the precise opposite of the conversation at hand. Which is precisely what my complaint was in the first place.




Here is an article explaining why lack of correlation does not imply lack of causation: http://blog.cholesterol-and-health.com/2011/01/lack-of-corre...

Ignorance is excusable, but the insulting tone you take on is not. Please stop ruining Hacker News.
