I mean the users of software. Instead of trying to predict what is the best design, create interfaces that make it easy to aggregate that data, and take that information at face value. When it comes to design, there often aren't facts (one may even suggest facts don't exist when it comes to design). Study the history of art to contest that. Otherwise, listen to users like they are humans, and see whether it matches with the designers advice. Simple.
