The phrase "takes at word" implies that someone believes something without questioning its validity or truthfulness. Antonyms for this phrase, therefore, would include expressions such as "doubt," "disbelieve," "question," or "challenge." Someone who takes at word may be considered gullible, naive or unskeptical, whereas someone who questions what they hear or read is often regarded as analytical, critical, or discerning. The act of taking someone at word can be dangerous in certain contexts, especially when dealing with unverified or false information. Therefore, it is important to cultivate a healthy dose of skepticism and critical thinking when encountering new ideas and communication.
