The Difference Between Correlation and Causality | Freakonomics

Freakonomics co-authors Steve Levitt and Stephen Dubner explain the difference between correlation and causality, and the tricky ways we have to devise to reveal a true causality.

to put it very simply:
correlation: two things happen at the same time, etc.
causation: one of those things is actually making the other thing happen.

I like what they're saying. It's very entertaining. EXCEPT! The difference between causality and correlation are still unclear! Why does this seem so confusing?

Hey, I know you probably got your answer, since it has been literally almost a decade since you asked this, but there's no reason why I can't answer it now.
As the video said, correlation is two things happening at the same time, and causation is one thing happening because of the other.
Here's an example of correlation: In the last few centuries, the population of pigeons has increased world-wide. Along with this, the number of pirate ships has went down world-wide. This is an example of correlation, or more pointedly, NOT an example of causation, because the pigeon population did not directly go up just because there are less pirate ships. If you slaughter every pigeon you see, it will not mean that a bunch of pirate ships will pop up suddenly. These two things just so happened to occur, but have no direct relationship to each other. Again, just because one thing occurred doesn't mean it has a direct relationship with the other.
Here's an example of causation: When you exercise at a heavy intensity, you feel sore and exhausted after. The direct relationship the two share is clear: you feeling exhausted happened because you worked out at a heavy intensity, and those muscles are particularly exhausted. Again, these things occur one after the other, and are directly correlated.

Causality and motive aren't the same thing!
