Tcaudillg, what do you think about Rick DeLongs dual-type? In my opinion he is pretty clearly IEE-LII. Reasons:
1.) He is very interested in logical consistency, which is absolutely atypical of average IEEs with Ti being their vulnerable function.
2.) Most socionics experts (Augusta, Gulenko, Bukalov, Reinin, Lytov, Ganin) are Alpha NTs. Theoretically, an IEE who becomes a socionics expert should at least have a 2nd type that is Alpha NT.
3.) If he had to choose a 2nd type, it would probably be LII as you can read here on his blog.
4.) According to the VI pattern I discovered, I'd probably type him as Ti-IEE due to his face being a "rounded square" (-> strengthened vulnerable function) as you can see here.
