“The rooster crows immediately before sunrise.

Therefore, the rooster causes the sunrise.”

This is obviously incorrect, and in logic terminology, is a ‘post hoc fallacy’, that is:

  • A occurred, then B occurred.
  • Therefore, A caused B.

When B is undesirable, this pattern is often extended to the inverse: Avoiding A will prevent B.

For those who like to think logically, it is worthwhile to learn the terminology – to improve the ability to identify and then deal with situations where others make logical fallacies.
