Physical attractiveness affects an individual's decision because the perception of quality improves. Physically attractive information sources increased the quality of consistent information needed to make decisions and further increased the selective exposure in decision-relevant information, supporting the researchers' hypothesis. Both studies concluded that attractiveness is driven by a different selection and evaluation of decision-consistent information.
Physical appearance has a significant impact on an individual's choice because it enhances the perception of excellence. Attractive sources of information improve the quality of consistent information required for making decisions and further increase the tendency to focus on relevant information that supports one's decision, confirming the researchers' theory.
