Name-calling, attacking a person’s character and using someone’s beliefs or traits to call their argument into question.For example, you can’t say that someone’s argument about dogs being better than cats is weak because they are also a Republican. It offers no real support to your argument for cats being better and it makes it look like you can’t think of anything better than poking at their personal beliefs.

Fallacy argumentum ad hominem

When you have good evidence, it makes it a lot easier to counter other people’s points while supporting your own. Prepare ahead of time. That way, when an argument comes up, you’re locked and loaded with answers to show your adversary that you know what’s what.

Find the Best Evidence

Winning an argument often comes down to who can go the longest without contradicting themselves and keeping sound logic, not direct persuasion of the other party.

Avoid Common Argument Fallacies

Even if you’re pretending. Listen to what they have to say and take it in. Don’t shake your head while they talk, cut them off mid-sentence, or look away like you don’t care about what they’re saying.If you appear to be giving the other side’s position a thoughtful review, then the solution you propose will seem to be far more sensible.

Be Calm and Courteous

Making up a scenario to make the opponent look bad. You’re assuming and making incorrect correlations. For example, if they don’t like orange juice, they must think oranges are bad for people.

Straw Man Fallacy

If they manage to throw you off with a really good point, try to stay on topic as best you can. Going off-topic can destroy your credibility, make you look defensive, and start new arguments. Stay focused on the current subject and keep your emotions out of it.If you’re dead set on winning the argument, you can keep pushing to make them upset and their argument will likely fall apart in anger.

Stay on Topic

Assuming something is caused by something else just because they happen to correlate. For example, the number of homeless people in an area might correlate to the crime rate for the same area, but crime doesn’t necessarily cause homelessness and homelessness doesn’t necessarily cause crime.

Correlation vs. Causation

Ignoring certain facts because of personally held beliefs. For example, you can’t cherry pick evidence that supports your claim and deny the evidence that doesn’t.

Confirmation Bias

Recognize that there are two issues to be addressed: both of your emotions and the situation at hand.<ul><li>Rein in the emotions first. Step away for a moment and let yourself cool down before you come back to the argument.</li><li>Try to keep your cool and show the other person respect.</li><li>Give them a chance to make mistakes and possibly realize they’re in the wrong.</li></ul>

Emotional arguments

The advantages are:<ul><li>You immediately come across as agreeable and willing to listen. This can disarm them and make it easier for you to persuade them later on.</li><li>You get to listen to what they say and look for weaknesses in their argument.</li><li>See if they can even support their own argument.</li><li>You give them a chance to mess up their argument.</li></ul>

Have Them Explain Their View First

Using statements that imply “all” of something or “every” thing is a certain way. For example, saying something like “all dogs pee on fire hydrants.” This would require you to be omniscient to make such claims, which is not possible.

Omniscience

<ul><li>Speak confidently, be concise, and try not to repeat yourself. </li><li>Give the appearance that you truly know what’s right from the beginning, even if you don’t have all of the facts. </li><li>Facts that can support your stance is helpful, but being convincing matters more.</li></ul><a href="http://lifehacker.com/how-to-sound-like-you-know-what-youre-talking-about-ev-5853250"></a>

Convince Them With Confidence

Winning can mean: <ul><li>resolving the conflict peacefully</li><li>getting them to admit they’re wrong about one thing and not the whole topic</li><li>intentionally giving in because you care about them.</li></ul>

Change What Winning Means to You

If enough people agree to something, it sort of becomes true in a social setting. It may not be 100% factual, but with a little supporting evidence, your buddies can be a better backup than any fact out there.It is, however,  best to avoid the fallacies of bandwagoning and appealing to authority. If you don’t have any evidence to support your claim at all, you and your group of supporters are just bullying people into admitting they’re wrong.

Look for Consensus to Back You Up

The right questions can help you break their argument down logically.Word your argument in the form of open-ended questions that force them to address your points.

Ask Them the Right Questions

Using a single personal experience as the foundation of your argument or your big piece of evidence. For example, your phone may have broken right after you bought it, but you can’t use that to argue that those phones are not worth the purchase for others.

Anecdotal Fallacy

Winning isn't everything, but it sure is nice. When you don't see eye to eye with someone, here are the best tricks for winning that argument. If you want to be the winner of the argument, act like you are. Speak confidently, be concise, and try not to repeat yourself.
