Onesidedness is a term used to refer to the state of being partial or biased towards one side more than the other. There are several synonyms for onesidedness, including partiality, bias, prejudice, favoritism, unfairness, one-eyed view, one-dimensional perspective, and lopsidedness. These words often describe a situation where the person or group has a predetermined and narrow perspective and fails to consider other factors or viewpoints that may be relevant. A person who suffers from onesidedness might be incapable of seeing or considering alternative perspectives, which may limit their ability to make informed decisions. Thus, it is essential to be aware of this trait and recognize that there is another side to every story.
