Which term refers to something that is misleading or deceptive?

The term that refers to something misleading or deceptive is "fallacious." This word is often used to describe arguments or reasoning that appears to be valid but is actually based on incorrect logic or false premises. In a debate or critical thinking context, identifying fallacies is essential because they can undermine the integrity of an argument and lead one to false conclusions.

The other terms don't align with the meaning of being misleading. "Scrupulous" refers to being principled or having a strong moral compass, suggesting honesty rather than deceit. "Dismal" denotes something that is bleak or gloomy, which does not imply deception. "Conceding" relates to admitting or acknowledging something, particularly in the context of yielding a point in a discussion or argument, which also does not connote any element of deception. Thus, fallacious is the term that clearly captures the idea of being misleading or deceptive.
