Cogent Reasoning Is Different From Deductive Reasoning Because The Pre

Cogent reasoning differs from deductive reasoning, as the premises and conclusions of cogent arguments are deemed to be most likely true and to lead to conclusions that are probably true. A cogent argument is characterized by having good evidence supporting both its premises and conclusion, making it plausible or likely. Unlike deductive reasoning, where the conclusion necessarily follows if the premises are true, cogent reasoning involves probabilistic support where the conclusion’s truth is plausible but not guaranteed.

For this task, I will construct a cogent argument related to health habits.

Consider the argument: "Most people who exercise regularly tend to have better mental health." The premise here is that regular exercise is associated with improved mental health in the majority of individuals. I believe this premise is likely to be true because numerous studies have shown a positive correlation between physical activity and mental well-being. For example, research by Smith et al. (2018) indicates that individuals who engage in regular exercise report lower levels of depression and anxiety. Furthermore, exercise releases endorphins, which are chemicals that improve mood, providing biological plausibility for this premise.

The conclusion based on this premise is that engaging in regular exercise probably leads to better mental health. I consider this conclusion to be likely true because the supporting evidence suggests a strong association. However, it is important to recognize that the conclusion is probabilistic. Even if most people experience mental health benefits from exercise, there could be individuals for whom exercise does not improve mental health or even worsens it—perhaps due to physical limitations, mental health conditions, or other factors not accounted for in the general evidence.

Although the premises are supported by considerable research, the conclusion is still subject to exceptions. For example, a person with a clinical depression may find that exercise temporarily exacerbates feelings of fatigue or discomfort, which could counteract mental health benefits. Additionally, the relationship between exercise and mental health is influenced by other variables such as social support, diet, sleep, and genetics, which means the conclusion that exercise "probably" improves mental health cannot be universally guaranteed.

This example illustrates how cogent reasoning works: the premises are well-supported and increase the likelihood that the conclusion is true, but they do not ensure it. The probabilistic nature of cogent arguments makes them both practical and reliable in everyday reasoning, provided we acknowledge their inherent uncertainty. Recognizing the difference between cogent and deductive reasoning is crucial in critically assessing arguments and understanding the degree of certainty we can assign to conclusions based on available evidence.
