The questionable cause—also known as causal fallacy, false cause, or non causa pro causa ("non-cause for cause" in Latin)—is a category of informal fallacies in which a cause is incorrectly identified.
An example that clearly states what false cause is can be given by, Every time I go to sleep, the sun goes down. Therefore, my going to sleep causes the sun to set.
Fallacies of questionable cause include:
- Circular cause and consequence
- Correlation implies causation (cum hoc, ergo propter hoc)
- Fallacy of the single cause
- Post hoc ergo propter hoc
- Regression fallacy
- Texas sharpshooter fallacy
- Jumping to conclusions
- Association fallacy
- Reductio ad hitlerum
- Guilt by association
