What technique is used when someone dismisses a critic by attacking their character instead of their argument?

The technique being described is known as "Ad Hominem," which is a Latin term meaning "to the person." This logical fallacy occurs when someone attacks the character or motive of the person making an argument rather than addressing the substance of the argument itself. By discrediting the individual, the focus shifts away from the argument's merit, which can manipulate the audience's perception and undermine the critic's valid points even though they may be sound.

In academic discussions and debates, it's essential to engage with the arguments presented rather than resorting to personal attacks. Ad Hominem tactics can detract from constructive dialogue, as they fail to provide a logical rebuttal and instead focus on personal attributes, which are irrelevant to the issues at hand. This method is often seen in a variety of contexts, from political debates to everyday conversations, where discrediting the opponent feels more immediate than addressing the content of their claims.
