Spurious Causations

What has the biggest association with death?

Cardiovascular disease?



Motor vehicle accidents?


The answer is birth. 100% of people who are born also die.

But while birth is a necessary precursor to death, is it fair to say that birth causes death? Hardly, unless you’re in an existential crisis.

Beware the post hoc ergo propter hoc fallacy; just because Event B follows Event A does not mean that A causes B.
