What are your choices?

... should what? Have you been given choices??

A person who is shown their argument commits a fallacy should first recognize and understand the fallacy that has been pointed out. Fallacies are common errors in reasoning that can undermine the validity or soundness of an argument.

To identify the fallacy, the person should carefully listen or read the explanation provided by the person pointing it out. It is important to be open-minded and willing to accept the possibility of having made a mistake. It may be helpful to ask for specific examples or further clarification to fully grasp the nature of the fallacy.

Once the fallacy has been identified, the person should reflect on their argument and honestly evaluate whether the criticism is valid. This involves critically examining the reasoning, evidence, and assumptions presented in the argument.

If the fallacy is indeed present, the person should acknowledge it and consider revising their argument. They can strive to understand why the fallacy occurred and learn from it. This may involve reevaluating their premises, finding alternative evidence, or adjusting the reasoning process.

It is important to note that recognizing and acknowledging a fallacy does not necessarily mean conceding the entire argument. The person can still defend their main point or perspective by providing a revised or strengthened argument that avoids the fallacy.

In summary, when someone is shown that they have committed a fallacy, it is crucial to engage in a process of reflection, understanding, and revision. By doing so, they can aim to improve their argumentation skills and enhance the overall quality of their reasoning.
