In Do Androids Dream of Electric Sheep?, at the beginning of the book, Rachael and Eldon Rosen attempt to make a deal with Rick Deckard when Rick thinks the empathy test he was going to use (the Voigt-Kampff scale) to hunt the 8 escaped androids does not work. They will give him a “live” (but actually robot) owl in exchange for his secrecy as to the fallibility of the Voigt-Kampff scale.
Why do they do this? I thought they didn’t want him to kill the androids? Why do they want to send him on his mission using this scale? Do they want him to accidentally kill a human so that bounty hunters lose credibility? Or do they want him to doubt himself so that he ultimately gives up on his hunt, or goes mad? That seems roundabout, I don’t understand why they don’t just blackmail him into not completing his mission or force him to tell his boss that their scale is erroneous.
Obviously it turns out the scale worked fine, but I’m still confused by their actions here.
