Open-mindedness is receptiveness to new ideas. According to Tjosvold & Poon, open-mindedness norms relate to the way in which people approach the views and knowledge of others, and "incorporate the beliefs that others should be free to express their views and that the value of others’ knowledge should be recognized." There are various scales for the measurement of open-mindedness. It has been argued that schools should emphasize open-mindedness more than relativism in their science instruction, because the scientific community does not embrace a relativistic way of thinking.
Open-mindedness is generally considered an important personal attribute for effective participation in management teams and other groups. According to What Makes Your Brain Happy and Why You Should Do the Opposite, closed-mindedness, or an unwillingness to consider new ideas, can result from the brain's natural dislike for ambiguity. According to this view, the brain has a "search and destroy" relationship with ambiguity and evidence contradictory to people's current beliefs tends to make them uncomfortable by introducing such ambiguity. Research confirms that belief-discrepant-closed-minded persons have less tolerance for cognitive inconsistency.
