Understanding the Differences: Plausible vs. Credible vs. Feasible vs. Probable vs. Possible

In the world of language and discourse, certain terms are often interchanged due to their perceived similarities. This article aims to clarify the distinctions between plausible, credible, feasible, probable, and possible. Understanding these nuances can significantly enhance your writing and communication skills, especially in academic, legal, and professional contexts.

Plausible vs. Credible

Credible refers to something that has been substantiated by empirical evidence. In contrast, plausible indicates something that is theoretically possible but lacks concrete evidence. To put it simply, credible statements are backed by real-world data, while plausible statements compel belief through reasoning and rhetoric.

For example, a scientific theory is credible if it is supported by numerous experiments and observations. However, an academic theory might be plausible if it seems logically sound and can be effectively argued, even if empirical evidence is lacking. The standard for plausibility is relatively lower compared to credibility; it lies closer to 'possible' than 'convincing'.

Feasible vs. Conceivable

Feasible implies that something can be done in practice, whereas conceivable is the ability to imagine something. In other words, feasible solutions have the practical means and resources to be carried out, while conceivable solutions are simply ideas that can be mentally visualized.

Probable vs. Possible

Probable indicates that something is likely to occur based on available evidence or reasoning, with some room for doubt. Conversely, possible suggests that something could happen but is not necessarily probable.

Probable occurrences are backed by more evidence for than against, or by evidence that inclines the mind to belief but leaves some room for doubt. On the other hand, possible events are simply hypothetical and may or may not exist, happen, or be done.

To illustrate, a weather forecast stating that there is a 70% chance of rain today is probable. Meanwhile, saying that a new product might sell in the market is merely possible, as there isn't enough concrete evidence yet to ensure its success.

Synonyms and Nuances

While these terms are often used interchangeably, they do have distinct contexts of usage. Plausible is typically applied in hypothetical scenarios, where it is used to describe theories or ideas that seem reasonable on the surface. In contrast, credible is often associated with testimony or statements that can be believed.

Historically, 'credible' literally meant 'not unbelievable' or 'convincing.' In a legal context, a witness is considered credible if their testimony is deemed believable. This standard is more stringent than mere plausibility. In legal terms, even if a defendant's innocence is plausible – that is, there is reasonable doubt of guilt – the defendant would be acquitted. To convict, a defendant's guilt would need to be highly credible, meaning it is likely and backed by strong evidence.

Conclusion

While these distinctions are somewhat colloquial and may vary in interpretation among different readers, understanding the nuances of these terms can greatly improve your communication and writing. Whether it's in an academic paper, a legal argument, or a business proposal, accurately applying these terms can make your arguments more compelling and persuasive.
