>quickly identify a contradiction or a counterargument and state it confidently.
How does this make this a "contrarian position"? At least I don't understand the negative connotation. To me this makes this "contrarian" at least a bit smarter than the one parroting the popular opinion...
The smarter thing to do would be to steelman the original position and not assume that the weakest of counterarguments — stated confidently and without much further analysis — sufficiently refute it.
Totally, so many people like to bring up a counter-argument and expect you to fully disarm it, but very few people will justify whether their argument is actually relevant or reasonable to the discussion at hand.
