No, the revelation principle is about how an indirect mechanism that implements a social choice function in dominant strategies also does so in a direct mechanism. Direct mechanisms are much easier to work with and this principle can be used to study many indirect mechanisms without all the complexity of such mechanisms involved.
interesting! So is G-S theorem the opposite of the revelation principle?
