I don't know if there are any studies on this but I remember years ago watching a TV program where identical twins were reunited after spending their whole life apart and growing up in different families even in different countries. There were superficial differences in adulthood when it came weight, clothes etc. but their non-verbal behavior was strikingly similar despite completely different life environments. So the identical twin argument of type being inborn seems somewhat plausible.

When it comes to very extroverted types with both 1D Ni and 1D Ti such as ESE and SEE, it's not unusual for them to be completely lost when it comes to their own perception of their identity. They really just can't introspect logically.
hmm, yes i get it's a splitting hairs debate but really it's not automatic to draw a conclusion from my experience, I've met omozigote twins that behaved and defined themselves differently, most common difference being that one is usually more quiet and taciturn, the other is more extroverted and bubbly but I think it reflects in their cognitive type overall too... honestly it depends, twins are all different as people are.

so i dont think you can judge someone's type from how they look and talk more than what they think and say (which seems the case for a lot of socionists) because that could actually be influenced by other things, upbringing, culture, context, moods etc
