Here's the wikisocion definition of

:
Introverted intuition is generally associated with the ability to recognize the unfolding of processes over time (how one event leads to another), have visions of the past and future, develop mental imagery, and see intangible hints of relationships between processes or objects.
So in typing someone using

... it would be more effective to have had an established relationship with the person of whom you're typing- the longer and more intensive the relationship is, the better. This would be because the more prior knowledge and understanding of the events and situations facing the person you are typing allows the

to be more reliable in its "ability to recognize the unfolding of processes over time (how one event leads to another), have visions of the past and future, develop mental imagery..." In me criticizing your questioning of my self-typing ("You don't know me"!), I was thus criticizing in part, your lack of information of my past and thus future behaviors which is obviously useful in typing someone. By applying your knowledge of socionics and types to someone's past behaviors, events, and situations you are able to get a better "mental image" of how they are in the present, and also the future. By creating these connections between past, present, and future behaviors of an individual, you are therefore able to see the consistent behaviors, actions, mannerisms, etc. that can help you determine someone's type. So here's an example- say you're trying to refute me being a SEE not directly to my face, but rather in your

mind. Assume that we've been good friends for a while too. Say we're at a bar and some girl who I've had beef with comes up to me, taps me on the shoulder and says "Just so you know- I think you're a bitch." By you seeing how I've acted in past maybe similar confrontations and my beef with this girl through

, you can come up with a pretty good idea of how I'm most likely going to react to her tapping me on the shoulder and calling me a bitch. This becomes a stronger prediction when applying your knowledge of socionics- is she a SEE? If she's a SEE she'll probably react _____, but if she's an IEE she may react by ______. This IRL example, would help for you to solidify your conclusion regarding my type. So because all you had going on were my posts and not my accounts or first-hand experience (for the most part) of the events and situations of my past, you would not have been able to generate a "mental image" of how I may react. Although you did have some ideas of how a typical SEE may react, without knowledge of my own unique and specific past behaviors, reactions, situations, etc. you would not have been able to type me as an individual.
