Answer :
In formal arguments like writing an essay or giving a speech, the type of logical reasoning that you should NEVER use is Abductive reasoning. Abductive reasoning is a form of logical inference that goes from an observation to a hypothesis that accounts for the observation but does not guarantee the truth of the hypothesis.
Here's why you should avoid using Abductive reasoning in formal arguments:
1. Lack of certainty: Abductive reasoning does not provide a certain or conclusive answer. It is based on the best explanation available at the time, which may not always be accurate or reliable for formal arguments where clarity and precision are essential.
2. Subjectivity: Abductive reasoning relies heavily on interpretation and subjective judgment, making it less suitable for formal contexts where objectivity and factual evidence are crucial for making a convincing argument.
3. Potential for error: Since Abductive reasoning involves making educated guesses or inferences based on incomplete information, there is a higher risk of drawing incorrect conclusions or misleading interpretations in formal arguments, which could weaken the overall credibility of your argument.
Therefore, when constructing formal arguments like essays or speeches, it is advisable to rely on Deductive or Inductive reasoning, which provide more structured and reliable methods for presenting logical arguments based on evidence and sound reasoning.
