non causa pro causa
C2Formal, academic, philosophical, legal

A logical fallacy where something is incorrectly identified as the cause of an event when it is not the actual cause.
The fallacy of mistaken or false cause; attributing causation to a factor that merely coincides with or precedes the effect without being genuinely responsible for it.
Linguistics
Semantic Notes
This is a technical term from logic and rhetoric, not used in everyday conversation. It is closely related to the post hoc ergo propter hoc fallacy, but can be broader, covering any incorrect attribution of causation, not just those based on temporal sequence.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation 'не причина для причины' is nonsensical. The concept is best rendered as 'ложная причина' (false cause) or 'ошибка в установлении причинно-следственной связи' (error in establishing a cause-effect relationship).
Common Mistakes
- Using it to mean simply 'a bad reason'. It must involve a mistaken claim of *causation*.
- Pronouncing 'causa' as /ˈkɔːsə/ instead of /ˈkaʊzə/ or /ˈkɔːzə/.
- Using it in informal contexts where 'false cause' or 'jumping to conclusions' would be more appropriate.

Frequently Asked Questions
They are closely related. 'Post hoc ergo propter hoc' (after this, therefore because of this) is a specific TYPE of 'non causa pro causa' that mistakes temporal sequence for causation. 'Non causa pro causa' is the broader category for any fallacy of false cause.
Almost never. It is a technical term from logic. In everyday conversation, people would say 'false cause', 'jumping to conclusions', 'confusing correlation with causation', or simply 'that didn't cause it'.
It is typically used as a noun phrase, often preceded by 'the fallacy of' or 'a case of'. Example: 'The detective warned against the non causa pro causa of assuming the threatening letter was the motive for the murder.'
Only for advanced learners (C1/C2) studying in fields like philosophy, law, formal debate, or advanced academic writing. For general English proficiency, understanding the concept of a 'false cause' is sufficient.
