A fundamental technique of this arms race is honestly consciously believing in your lies. So given the OP's proposal, which incentives conscious lying, people feel uncomfortable.

The thing that can be corrupted is the general level of trust in conversation - if you're not lying and you're reasonably certain the other person also isn't lying (consciously), you can relax (consciously), and that feels good. So we don't like proposals for new social techniques or conventions where to get ahead (be hired) we would have to lie more than we think we do now.
