Using two senses rather than one makes us better. But does it make us also surer? Consider this detour: You hear a story from one friend, or you hear the same story, by two independent friends. In this project, we consider whether we are, as it seems we should, be more confident of what we perceive with two senses, even though we may not be more correct. We also consider how this confidence reflects the confidence we have in each sensory information: Is it an average? is it related to the reliability of each sense?
