Just saw pianosinger's thread about unimaginative intuitives and imaginative sensors and thought it would be a good idea to start a thread about this.

There are some extraverts that can be shy and can appear introverted and usually they tend to be intuitives. Also there are introverts that can be talkative and can appear extraverted and usually they tend to be sensors.

Anyways, I think this is why it can make it more difficult to type yourself because then you have to look at the functions to figure out what you really are rather than your social behaviour, and in the end functions are merely metaphorical representations of actual cognitive functions.
