Pre-notions are ideas or opinions formed before encountering a situation, event, or person. Antonyms for pre-notions could be an open mind, absence of judgment, a blank slate or an unbiased viewpoint. Having an open mind requires one to be receptive to new ideas, facts, and experiences without any preconceived notions. Absence of judgment is an attitude of impartiality and refraining from forming opinions before gaining enough knowledge. A blank slate means being free from any pre-existing ideas or concepts, having an unbiased viewpoint, and not letting previous experiences cloud your judgment. An unbiased viewpoint is having fairness and impartiality towards a situation or person regardless of any preconditions, without any prejudice or favoritism.
