How much should an RPG have rules for social interaction?

There's a certain element of that, to be sure, but it should be on smaller things. My ability to give a speech should not directly translate to my PC's ability to do the same, any more than my ability to program in Matlab directly translates to my PC's ability to code a neural network.

But your ability to program into MatLab could help you optimize your character into the best character possible, and achieve the highest degree of success in coding a neural network.
