bias
⚖️ pre- (before) + juicio (judgment) = a judgment made before knowing the facts
Prejuicio splits into pre (before) and juicio (judgment, like English judge). Prejudice is literally pre-judging: deciding before you have evidence. The Spanish juicio and English judge both come from Latin iudicium.
