Significado

aparentemente correcto pero en realidad erróneo; falaz

A formal and slightly literary expression used in academic, journalistic, and critical writing to characterise arguments, claims, or reasoning that sound reasonable but do not withstand scrutiny. Closely related to the concept of sophistry. Serves as a warning to critically evaluate apparently sound logic.
