#Resource Post hoc ergo propter hoc Post hoc ergo propter hoc is a Latin phrase meaning "after this, therefore because of this". It is a logical fallacy assuming that because event B happened after event A, event A must have caused event B. This error confuses temporal sequence with causation, often mistakenly attributing causality to coincidence. Merriam-Webster Merriam-Webster +3 Key Aspects of the Fallacy: Definition: It is an informal fallacy where one incorrectly assumes that a chronological order of events implies a cause-and-effect relationship. The Error: It fails to consider that correlation does not equal causation. Just because one event follows another, it does not mean it was caused by it. Examples: Superstition: Breaking a mirror and experiencing bad luck later, leading to the belief that the mirror caused the bad luck. Daily Life: A person turns on a fan, the power goes out, and they believe the fan caused the outage.
