During her years of college, Dominique discovered that her three favorite subjects were astronomy, chemistry, and political science. She chose to major in astronomy because she had seen data indicating that science majors earn higher-than- average wages and because she liked astronomy better than both chemistry and political science. Upon graduation, however, she learned that average wages in chemistry fields were 20 percent higher than average wages earned by astronomers. Did Dominique's behavior violate the rationality assumption?
