In this short, Robert Cialdini explains that counterarguments are more potent than simple arguments because they directly puncture an opponent’s position, casting doubt on the opponent’s knowledge or honesty. This perceived lack of expertise or truthfulness not only undermines the specific issue being debated but also spills over, damaging the opponent’s credibility on any subsequent topics they might raise. The effect is described as a “torpedo” that can systematically erode a person’s overall trustworthiness.

It is correct. And the reason that counterarguments are more powerful than arguments is that they puncture the opponent's position and render the opponent either, on the one hand, not knowledgeable enough to have a full understanding of the situation, or— and this is the one that's most devastating— not honest enough to be telling you the whole truth. That interpretation doesn't just apply to the particular issue at hand. It applies to subsequent issues that your opponent would try to raise. If you've punctured his or her credibility, then that carries across the border to other issues. Very powerful. It's a torpedo of undermining that person's credibility, and that's why counterarguments are so powerful.
