This is really interesting, and I wonder if focus groups can't also play a role in creating object labels that better reflect the audience. Like if you brought in a group of people with diverse ages, backgrounds, etc and had them react to a bunch of objects, recorded their reactions, and used those to influence the questions and facts given in the label? (Or is that too creepy? Haha)
