>[!abstract] >A falsidical paradox is a paradox that arises from reasoning that appears logically sound but actually contains a hidden fallacy, leading to a false conclusion. The term (from falsidicus, “deceptive”) distinguishes these from [[Veridical paradox|veridical paradoxes]], which are true but counterintuitive. Falsidical paradoxes are pedagogically useful because they expose how subtle errors in logic or mathematics can produce persuasive but invalid results. >[!example] Examples >- [[Proof that 1 = 2]] >[!related] >- **North** (upstream): — >- **West** (similar): — >- **East** (different): [[Antinomic paradox]], [[Veridical paradox]] >- **South** (downstream): —
