What are some things you can do, when you happen to hear a tour group leader spouting some blatantly inaccurate information at their participants? Whether it’s a creationist group visiting the evolution wing of a museum, or an Official museum tour where the leader was ill-informed about the topic (happens a more often than you might think), most people tend to leave them alone. But, what if you are the type of person that just simply can’t stand idly by?! I will propose a strategy for addressing the situation that is diplomatic (you can NOT be mean!), pragmatic (using utility as a motivation for changing opinion), and concise (you might only have 30 seconds to talk). We can compare its strengths and weaknesses against any other approaches anyone else might have.
