We find those who disagree with our art evaluations as more influenced by biases (conformity, financial incentives); reminding us of art preferences as “matters of opinion” reduced this thinking, but did not eliminate it

Seeing the subjective as objective: People perceive the taste of those they disagree with as biased and wrong. Nathan N. Cheek  Shane F. Blackman  Emily Pronin. Journal of Behavioral Decision Making, September 11 2020. https://doi.org/10.1002/bdm.2201

Abstract: People think that they see things as they are in “objective reality,” and they impute bias and other negative qualities to those who disagree. Evidence for these tendencies initially emerged in the domain of politics, where people tend to assume that there are objectively correct beliefs and positions. The present research shows that people are confident in the correctness of their views, and they negatively judge those who disagree, even in the seemingly “subjective” domain of art. Across seven experiments, participants evaluated paintings and encountered others who agreed or disagreed with their evaluations. Participants saw others' evaluations as less objective when they clashed with their own, and as more influenced by biasing factors like conformity or financial incentives. These aesthetic preferences felt as objective as political preferences. Reminding people of their belief that artistic preferences are “matters of opinion” reduced this thinking, but did not eliminate it. These findings suggest that people's convictions of their own objectivity are so powerful as to extend to domains that are typically regarded as “subjective.”
