Final answer:
The atmosphere effect dictates that quantifiers such as 'all,' 'some,' and 'no' in argument premises influence evaluations of conclusion validity. Avoiding logical fallacies and considering alternative arguments are key in argument assessment.
Step-by-step explanation:
According to the atmosphere effect, the presence of the words all, some, or no in the premises of a deductive argument can influence the person's evaluation of the validity of the conclusion of the argument. When assessing the validity of an argument, it is important to avoid common pitfalls such as premises that are false or questionable, premises that contain the conclusion (circular reasoning), or premises that are inadequate to support the conclusion. Furthermore, the presence of alternative arguments with equal or greater support is also crucial to consider when evaluating an argument.
