Sometimes you can sacrifice a bit of virtue to signal intelligence. For example, when people talk in real life, interrupting other people may give you an opportunity to say something clever first. Or you can make a funny joke that shows how smart and quick you are, even if you know that this will derail the debate.
Then there is contrarianism for signalling sake. You disagree with people not because you truly believe they are wrong, but to show that they are unthinking sheep and you are the brave one who dares to oppose the popular opinion (even if you actually believe the popular opinion to be correct, and the thing you said is just an exercise in finding clever excuses for what is most likely the wrong answer). This can cause actual harm, when people convinced by your speech do the wrong thing instead of the right one.
