The word "prepossessioning" refers to impressing or influencing someone before they have the chance to form their own opinion. The term can be replaced with synonyms like "prejudice," "bias," "impression," or "influence." If someone is prepossessing, they may be referred to as "persuasive," "compelling," or "charismatic." The opposite of prepossession would be objectivity or neutrality. It's important to be aware of preconceived opinions and not allow them to cloud our judgments. Using words like "impression" or "influence" may be less judgmental and more neutral, allowing for a more informed perspective.
