Companies do not act on the basis of the best evidence. They merge even though much research shows that mergers destroy value. They use forced-curve ranking systems for performance reviews even though extensive evidence documents the harmful effects. There is no reason to believe they would behave any differently with respect to their human capital.
The political divide about surveillance is about whether or not the ends justify the means. I believe they don’t, or rather that those who focus on the immediate benefits of surveillance are myopic to its other effects on society. Those people by the way are well meaning – always keep Hanlon’s Razor in mind : never attribute to malice that which is adequately explained by stupidity. What it means about surveillance is that we don’t need to have intent to create a fascist regime – we can just sleepwalk into it.
