Type and personality are not the same according to Socioincs. In theory, 16 people of the same type (example ESFj) can all have different personalities.

Type has nothing to do with the way one behaves.

Introverts can appear extraverted and vice versa. Feeling types can appear logical. Sensing types can appear intuitve. And so on.

Types is only to do with how you metabolise information.

So does that not mean it is impossible to judge the type of a person?
