What do modal qualifiers in an argument signify?

Modal qualifiers in an argument are terms that indicate the degree of strength or certainty related to the conclusion being drawn. They help express how confident the speaker is regarding the statements being made, typically through words like "might," "could," "should," "usually," or "always." By using these qualifiers, the arguer can communicate whether they believe the conclusion is definite, probable, or merely possible.

For instance, if an argument concludes that "students usually perform better with more study time," the qualifier "usually" is used to indicate that while the argument holds for many cases, it might not apply universally. This level of nuance helps to clarify the strength and robustness of the conclusion, making it more accurate and reflective of the real world.

Understanding modal qualifiers allows for a more critical evaluation of arguments, as it highlights the speaker’s stance on certainty and recognizes the complexities inherent in making claims about the world.
