What method involves starting with a known claim or belief to determine what follows?

• A. Deduction
• B. Abductive reasoning
• C. Inductive reasoning
• D. Prototype theory

Answer: (A)

The method that involves starting with a known claim or belief to determine what follows is deduction. Deductive reasoning takes a general principle or established fact and applies it to a specific case to reach a logical conclusion. For example, if one accepts the general premise that all humans are mortal, and then encounters an individual who is a human, deduction leads to the conclusion that this individual is mortal as well. This process is structured and relies on the validity of the initial premises to ensure the accuracy of the results.

In contrast, abductive reasoning focuses on generating the most likely explanation for observations, which may lead to a conclusion that is plausible but not definitively proven. Inductive reasoning works the other way around by observing specific instances and inferring a general principle, which doesn’t guarantee that the conclusion will always hold true. Prototype theory relates to cognitive psychology in terms of how individuals categorize objects and concepts based on a prototype or ideal example, rather than reasoning methods.
