There's a difference between someone introverted and introspective. A Tarot reader is probably more introspective than most, since that's part of the package, but they need not necessarily be introverted.
That's a good point. I did some reading about personality factors, and the key take-away I got was that personality is a product of socialization, it's not an innate quality like temperament. Introversion could be the outcome of failed or flawed socialization, after which self-reliance seems like the best course because social interaction proved unrewarding. So turning inward in an emphatic way could be primarily a response - or defense - mechanism, not a matter of choice.
I think both of these are excellent observations, and as a lifelong INFP (though people are often fooled by my Leo mask, like in Apollonia's case
) I can attest that at least some of it is true in my case. However, I think that some people are born with a tendency to introspection, and those people tend more often than not to be introverted. For me that would be the real root of introversion.
Western psychology has a nasty tendency to pathologize traits that Western society deems as undesirable, and introversion is one of them. Let's not forget that, to this day, certain schools still tend to consider homosexuality as a consequence of failed heterosexuality. So I'd say that introspection is in itself an obstacle to Western-style socialization (particularly in the States, where people are pushed to be in "look at me" mode all the time), and not the other way around, or at least not so much.
