Dissuadable means capable of being persuaded or convinced to not do something. Its antonyms, on the other hand, refer to words that describe a person who is not open to persuasion or who cannot be convinced. These include unyielding, stubborn, obstinate, intransigent, immovable, unrelenting, uncompromising, uncooperative, and inflexible. These words all suggest a lack of willingness to change one's mind, attitude or point of view. If people cannot be dissuaded from their beliefs or course of action, it can be problematic as it leads to stubbornness during decision-making processes, resulting in rigidity and lack of understanding of other people's perspectives.
