Biais vs. parti pris
While both terms relate to a lack of neutrality, biais often refers to an unconscious distortion, a logical error, or a specific angle, whereas parti pris implies a conscious, deliberate choice or a firm stance taken on a subject.
Biais
C1This word is often used in psychological, statistical, or logical contexts. It refers to a systematic distortion or a slant that influences perception, often without the person realizing it. It acts like a filter that skews reality.
