All these conclusions seem to require simultaneity of causation. If earthquakes almost always caused recessions, but not until one year after the earthquake; and if recessions drastically increase the number of burglars, but not until one year after the recession; then drawing any of the conclusions you made from a survey taken at a single point in time would be entirely unwarranted. Doesn't that mean you’re essentially measuring entailment rather than causation via a series of physical events which take time to occur?

Also, the virtue theory of metabolism is so ridiculous that it seems only to be acting as a caricature here. Wouldn't the theory that “exercise normally metabolises fat and precursors of fat, reducing the amount of weight put on” result in a much more useful example? Or is there a subtext I'm missing here, like the excessive amount of fat-shaming done in many of the more developed nations?

Some of the inferred subtext is being extracted from earlier posts that refer to diet while ostensibly discussing other issues.

Ahh, thanks.
