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.
It will be interesting if this is reproducible (or maybe the
comments put a bad taste in my mouth :-).
