"In the 1990s, a team of researchers led by Harvard Business School’s Teresa Amabile conducted an intriguing experiment with visual artists. Amabile asked 23 painters and sculptors to randomly select 10 of their commissioned works and 10 of their non-commissioned works. Then she presented the 460 pieces to a panel of art experts – museum curators, art historians, gallery owners, and so on, who didn’t know where the works came from – to evaluate the art.
“Our results were quite startling,” Amabile and her colleagues reported. “The commissioned works were rated as significantly less creative than the non-commissioned works, yet they were not rated as different in technical quality"
