One of the most recent par­a­digms that we’ve used to try to get this under exper­i­men­tal con­trol is to ask peo­ple to act out pre­tend harm­ful actions. So for instance, we’ll give them a dis­abled hand­gun. We’ll show them that it’s fake. That it couldn’t pos­si­bly harm a fly. We put it in their hands and then we ask them to shoot us in the head.
