The concept of being inclined to think can have polar opposites in the form of antonyms. One antonym could be "unbiased," meaning without any predisposition or favoritism towards a particular idea or thought process. Another antonym could be "disinclined," indicating a lack of natural tendency towards thinking or contemplating any particular notion. Conversely, "prejudiced" is a term often used to describe someone who holds strong beliefs that are not backed by evidence, and therefore not inclined to think critically. Similarly, "closed-minded" suggests unwillingness to consider diverse perspectives or be open to new ideas. These antonyms help to provide a counterbalance to the idea of being inclined to think one particular way.
