What type of fallacy is depicted when someone shifts the focus of a conversation to a different topic entirely?

The type of fallacy depicted when someone shifts the focus of a conversation to a different topic entirely is known as Diversion. This tactic involves redirecting the discussion away from the original issue, often to avoid addressing the argument or to introduce a topic that may be easier to discuss or argue about.

By employing diversion, the person might distract the audience or the opponent with unrelated information or issues that do not pertain to the original question or concern, which can mislead the conversation and undermine logical reasoning. For example, in a debate about environmental policies, if one participant starts discussing unrelated personal anecdotes or entirely different issues, they are diverting from the topic at hand.

In contrast, the other options refer to different argumentative strategies or fallacies. Victory by Definition focuses on winning an argument by redefining terms in a way that makes one’s position seem superior. Disproving a Minor Point involves challenging a small detail of an opponent's argument instead of the broader issues at stake. Attacking a Straw Man occurs when someone misrepresents an opponent’s argument in order to make it easier to attack. These concepts do not involve the act of shifting topics entirely, which distinguishes diversion as the correct choice.
