I wish the Social interaction chart was a bit more flexible. I don't think self Discipline helps you know someone is using Deception. It should be Perception of their tells or Knowledge of the facts in question.
Or you could use deception to spot the deception. Because you can't bulls**t a bulls**tter.
While I approve of your sentiment, that would make Deception a little too good.
The thing that I do like about the social chart is that it makes it clear which skills are active (or offensive) and which are defensive. Deception is primarily on offense.
