How can you prevent making logical fallacies in arguments?

Focus on looking back over your arguments frequently. Keep yourself on track for the point that you're trying to create by staying both true and relevant to the topic at hand. Also, provide good support for your argument. Avoid making assumptions. Lastly, compare your argument to the list of all fallacies. Does your piece fall under any of those at any time? If so, you then know what to fix. Hope this helps.
