Short Answer 
To construct a credible argument, avoid personal anecdotes and logical fallacies, acknowledge opposing viewpoints respectfully, and support your claims with verifiable evidence while ensuring logical consistency in your reasoning.
Step 1: Avoid Personal Anecdotes and Fallacies
When constructing an argument, it’s vital to refrain from relying on personal anecdotes or engaging in logical fallacies. Personal anecdotes may be subjective and lack broad relevance, while logical fallacies undermine the overall credibility of your argument. Instead, focus on the strength of your reasoning and objective evidence to support your claims.
Step 2: Acknowledge Opposing Viewpoints
To enhance the credibility of your argument, actively acknowledge and counter opposing viewpoints. This practice demonstrates that you have considered different perspectives, which adds depth to your argument. Aim to address counterarguments respectfully, using factual evidence rather than emotional appeals or personal attacks, to maintain a respectful discourse.
Step 3: Utilize Verifiable Evidence and Ensure Logical Consistency
Employ a variety of verifiable evidence to strengthen your argument while ensuring your reasoning remains logically consistent. This means assessing the facts you present for relevance and accuracy, as well as matching your evidence types to your subject matter. Additionally, critically evaluate both your own argument and those of others to uphold the integrity of your reasoning process.
