When a person argues logically, he's more likely to convince people of the validity of his claims or get them to agree with him. Even if people are unable to pinpoint a fallacy involved in an argument, they can detect the argument's invalidity if it’s constructed illogically.

With deductive inferences, the conclusion must be true if the premises are. For instance, the Pythagorean Theorem is proven true after treating the postulates as true in elementary geometry.
