Correlation is not causation
What XKCD says:
The mouseover text on the original says “Correlation doesn’t imply causation, but it does waggle its eyebrows suggestively and gesture furtively while mouthing ‘look over there’.”
It is a bad habit, hard to break, the temptation is great.

Often times I see that the style of astronomers’ exercising correlation studies follows statistical methods for understanding causality. Nice cartoon!!!
