The simple regularity theory is a good first pass at a regularity theory of causation, but one might worry that mere regular succession isn’t enough to make for genuine causation. For example, it is undoubtedly the case that every time your favorite football team has ever won a game, the sun has risen the following day. Your team’s winning is regularly followed by the sun’s rising. And yet it doesn’t follow that the cause of the sun’s rising on those days is your team’s win.
