[General] Are there non-psychically capable people who have such natural mental strength and will that they can resist a psychic invasion of their mind?

Generally, psychic powers are portrayed with people falling into three general categories: (1) psychically capable; (2) neutrally capable/non-psychic; (3) actively anti-psychic powers. 

In several universes there are examples of non-psychic people being taught techniques to resist someone invading their minds. 

However, what I’m wondering about is if there examples of non-psychic people who just have such strong mental will that they could resist a psychic? For instance, when we see Picard being tortured by the Cardassians we see his mental will in resisting them. I’m thinking about a psychic trying to read Picard and his internal voice being able to resist them. Does anything like that exist?

Storm in X-Men is considered extremely resistant to mental manipulation. 

Superman has also had training to resist psychic influence, and Joker simply can't have his mind read because it's too much of a chaotic and unstable mess for anyone to make sense of.
