Final answer:
The author's use of a false dilemma impacts the argument by leading the reader or employee to doubt the credibility of the presented information, as it limits the available options, potentially resulting in biased reasoning and misinterpretation of situations.
Step-by-step explanation:
Impact of False Dilemma on an Argument
The use of a false dilemma by an author can significantly impact the credibility and logical soundness of their argument. Presenting a situation as having only two possible outcomes, when in fact there are more, is a common reasoning fallacy. This tactic may compel the reader to choose between two extremes, which can be problematic when not all valid options are considered.
In the case of the employee in a retail setting, the use of a false dilemma would likely lead the employee to doubt the manual's credibility because it omits other valid options and scenarios that could be relevant. This could ultimately shape the employee's perception of the company policies and their approach to resolving issues such as customer satisfaction, workplace expectations, or even personal success within their role.
At times, the presentation of a false dilemma might not only limit the available choices but also result in biased reasoning. Neglecting to acknowledge alternative perspectives or possibilities could lead to misguided conclusions, much like the test results being misinterpreted in the given example due to a bias against the subject of the test.
