What Is GDP?
GDP is the standard scoreboard for the size of an economy. This piece explains what it includes and what it leaves out.
Two things changing together might mean one caused the other, but it might also mean the arrow runs backward, a third factor is involved, or the pattern is just noise.
Four possibilities
This is the story people usually jump to first, but it is not the only explanation.
Sometimes the direction of the relationship runs the opposite way from the one you assumed.
A hidden third factor can make two things move together without either one causing the other.
With enough data and enough comparisons, unrelated patterns sometimes line up by chance.
The caution
That one habit protects you from a surprising amount of bad reasoning.
Why it matters
Strong explanations do more than notice patterns. They test timing, alternative causes, and whether the data is broad enough to support the claim.
Three checks worth making
A lurking variable is often the cleanest explanation for a suspiciously neat pattern.
A cause must come before its effect. If the sequence is wrong, the claim is wrong.
Small or cherry-picked data can make random noise look meaningful.
