The attraction effect violates choice consistency, one of the central assumptions of economics. I present a risky choice experiment to test it and disentangle some of its explanations. I find the attraction effect, but in a smaller magnitude than previously thought. I uncover a ‘range effect’ that shows that people weight more attributes whose range increases. I also show that the aggregate results hide considerable heterogeneity between subjects.
