Research suggests that visiting art exhibitions can temporarily promote social thinking and open-mindedness, but the duration of these effects may vary. Studies have found that exposure to art can increase activation in brain regions associated with empathy and social cognition, such as the temporoparietal junction and prefrontal cortex. This activation can lead to enhanced social perspective-taking, increased appreciation of diversity, and reduced stereotyping.

However, the duration of these effects is not well-established and can depend on various factors. Some studies suggest that the effects may last for a few hours or days after the art experience, while others indicate that they may dissipate more quickly. Factors such as the individual's level of engagement with the art, their prior attitudes and beliefs, and the specific type of art they encounter may influence the longevity of these effects.

Overall, while visiting an art exhibition can transiently promote social thinking and open-mindedness, the duration of these effects may vary depending on individual and contextual factors. Further research is needed to better understand the persistence of these effects and the conditions that may enhance their sustainability.
