Acting "wrongheadedly" means doing something in a misguided or foolish way, often due to a faulty judgment or incorrect understanding. It implies a lack of clear thinking or common sense, leading to poor decisions. ðĪ It is similar to being stubborn, but with a greater emphasis on the incorrectness of the approach. Think of a character in a mystery novel who jumps to the wrong conclusion and pursues the wrong suspect; that's wrongheadedness. It suggests acting against logic or reason.
