It is worth noting that I think Survivor treats their cast very differently. It is hard to know exactly, as I have never seen directly, but I have spent time with the crew from Survivor, and spent some time on location while they were shooting. They treated me with amazing grace and I am forever grateful for their time and hospitality. I imagine that their record may not be perfect, but I think their approach to this is more like a sport with athlete, than a prison guard in the Stanford Prison Experiment.
