Tendentiousness refers to the inclination towards a particular opinion or viewpoint, often with a biased or prejudiced attitude. Synonyms for tendentiousness include partiality, prejudice, bias, partisanship, and opinionatedness. These words all describe a strong leaning towards one side of an issue, often with disregard for contrary evidence or perspectives. Other synonyms for tendentiousness include dogmatism, fanaticism, and narrow-mindedness. These terms convey a more extreme and inflexible bias. On the contrary, objectivity, impartiality, and fairness are antonyms of tendentiousness, suggesting a more unbiased and balanced approach. While having an opinion is a natural human tendency, avoiding tendentiousness and striving for objectivity is essential for critical thinking and informed decision-making.
