FOR many education advocates, the arts are a panacea: They supposedly increase test scores, generate social responsibility and turn around failing schools. Most of the supporting evidence, though, does little more than establish correlations between exposure to the arts and certain outcomes. Research that demonstrates a causal relationship has been virtually nonexistent.
A few years ago, however, we had a rare opportunity to explore such relationships when the Crystal Bridges Museum of American Art opened in Bentonville, Ark. Through a large-scale, random-assignment study of school tours to the museum, we were able to determine that strong causal relationships do in fact exist between arts education and a range of desirable outcomes.
Students who, by lottery, were selected to visit the museum on a field trip demonstrated stronger critical thinking skills, displayed higher levels of social tolerance, exhibited greater historical empathy and developed a taste for art museums and cultural institutions.
Crystal Bridges, which opened in November 2011, was founded by Alice Walton, the daughter of Sam Walton, the founder of Walmart. It is impressive, with 50,000 square feet of gallery space and an endowment of more than $800 million.
