Are LSI the most intelligent type. Like if you think about it, Si and Se don't do anything for intelligence. Se is just hardcore stacking the other function you have, but only if it's not the base, which is kind of troll. Basically if you think about it, it's just Ti+ which is stacking shitloads of rules, and Se forcing yourself to stack shitloads of rules. It's like a one two punch, extremely simplistic but effective.

All the other types, have something to fall back on, the traditional "intelligent" types, the "NT"s have either their logical functions or intuition to interpret data. The same sort of goes for "NF"s but in a different sphere, but they still have intuition for doing intellectual things. Even Delta ST has Si for storing info. LSI literally just has Ti+ and is forcibly making it stronger. I find that kind of admirable. It's like having no real talent or special tricks and having to concentrate just to improve one thing to make it work for EVERYTHING else. But its also troll.
