preconceived notion

A preconceived notion is a fixed idea or belief that someone holds before being presented with new evidence or information. It is a form of mental shortcut or bias that can influence how we perceive and interpret new information, leading us to make judgments or decisions based on our existing beliefs rather than on objective facts.

Preconceived notions can be formed from a variety of sources, including personal experiences, cultural and social influences, and media messages. They can be positive or negative, and can be based on accurate or inaccurate information.

Preconceived notions can be problematic because they can lead to misunderstandings, misunderstandings, and close-mindedness. It is important to be aware of our own preconceived notions and to actively seek out diverse perspectives and information to challenge and expand our thinking. This can help us make more informed and unbiased decisions.
