While it may be true that nobody actually "wins" an argument—especially certain types—there are still times you want to appear to come out on top. Whether you're having a good-natured debate, or hoping to put someone in their place, you'll want to avoid these 30 guaranteed ways to lose.

This graphic from Curtis Newbold—The Visual Communication Guy—highlights the biggest reasons you could end up looking like a fool in your next bout. Things like attacking a person's character instead of using (ad hominem), bandwagoning, or letting your own personal biases get the best of you. The graphic is organized to describe the reason first, then name the fallacy it belongs to, and finally give you an example so you can be aware of what you might be doing or should avoid doing in the future. There are plenty of ways to win an argument, but one of the best ways to win is to not sink your own ship.
