Salina, the expeditor at RingPro Gasket Manufacturer, writes a memo asking her manager to buy her a new computerized system for tracking customer orders. She claims that if she does not get this system, chronically late deliveries will ensue. Her manager turns down her request. Salina made the mistake of using?

Either/or logic is a form of logical fallacy that occurs when an individual believe that he/she only has one option in a certain situation, while overlooking any other possible solution that might be used.

We can see this in the example above.

Salina believed that if her manager does not buy her new computerized system for tracking customer orders, late deliveries will ensue.

The manager rejected the request because Salina overlooked other possible solutions.

For example, Salina could seek a help online to create a filing system from free programs. This way, she could make sure that the deliveries stay on time without having to buy a new computerized system.
