Pattern
The form of the post hoc fallacy can be expressed as follows:
-
- A occurred, then B occurred.
- Therefore, A caused B.
When B is undesirable, this pattern is often extended in reverse: Avoiding A will prevent B.

Famous quotes containing the word pattern:
“In this lucid and flexible pattern only one thing remained always stationary, but this fallacy went unnoticed by Martha. The blind spot was the victim. The victim showed no signs of life before being deprived of it. If anything, the corpse which had to be moved and handled before burial seemed more active than its biological predecessor.”
—Vladimir Nabokov (1899–1977)
“Each child is an adventure into a better life—an opportunity to change the old pattern and make it new.”
—Hubert H. Humphrey (1911–1978)
“A two-week-old infant cries an average of one and a half hours every day. This increases to approximately three hours per day when the child is about six weeks old. By the time children are twelve weeks old, their daily crying has decreased dramatically and averages less than one hour. This same basic pattern of crying is present among children from a wide range of cultures throughout the world. It appears to be wired into the nervous system of our species.”
—Lawrence Kutner (20th century)
