Which of these is NOT a technique used in logical reasoning?

Clarity is essential for effective communication and understanding, but it is not a technique in logical reasoning itself. Logical reasoning techniques are methods used to draw conclusions or make inferences based on premises or evidence.

Hasty Generalization, Post Hoc reasoning, and Selected Instances are all techniques that involve specific logical processes. Hasty Generalization refers to making a broad conclusion based on insufficient evidence. Post Hoc reasoning suggests that if one event follows another, the first must be the cause of the second, which can lead to erroneous conclusions. Selected Instances involves drawing a conclusion based on a limited number of examples rather than a comprehensive set of data, which can also result in faulty reasoning.

In contrast, clarity serves more as a necessary quality for presenting arguments rather than a method of reasoning. It ensures that the premises and conclusions are understandable, but it does not qualify as a logical reasoning technique that contributes to forming conclusions or arguments.
