The Post Hoc Ergo Propter Hoc Fallacy in Critical Thinking
Post hoc ergo propter hoc ("after this, therefore because of this") is an informal fallacy in which one concludes that because one event occurred after another, the first event must have caused the second — treating mere temporal sequence as sufficient evidence of causation. This concept belongs to the domain of critical thinking / informal logic, specifically the study of causal reasoning and argument evaluation, and it illustrates the broader principle that establishing a causal relationship requires evidence beyond temporal order alone (e.g., a mechanism, controlled evidence, or ruling out alternative causes).
