The dataset contains questions from three domains - Geography, Movies, and Paintings where multiple options are shown to voters and they are asked to provide two information - 1) Their vote on what the ground truth ranking of the alternatives is 2) Their prediction on what everyone else thinks the ground truth ranking of the alternatives is. The criteria for ranking is decreasing order of population for Geography, decreasing order of gross box office lifetime earnings for Movies, and decreasing order of auction prizes for paintings.
