It's true that people in a usability test don't behave exactly the same as at home, but that actually proves my point. If they're obviously trying to be positive and helpful (no matter how much you tell them to relax and be honest) because they're constantly saying nice things about the site or app, then it's even more noteworthy to hear any negative comments or see that they're confused. Especially in the beginning of the session when their energy is higher.
