What?
SEIs I know (who aren't me):
- Psychology
- Philosophy and ecology
- Lay philosopher and music theory + multi-instrumentalist and teacher
I'll also be changing to a philosophy major next semester, if I can.
The ESE I know is also doing philosophy and English literature.
I think the less intelligent ones may be less intellectually inclined, but that's intelligence, not type.
Which is not, of course, to say the intellect makes the intellectual, but I've noticed a consistent pattern with intelligent Alpha SFs I know toward intellectualism.
In the case of the SEI, there's actually even a Socionics justification. Si+Ti leads to double-external, highly deliberate thinking, coupled with dynamic/negativist (dialectical-algorithmic) leading to spontaneous insights and a need to resolve cognitive dissonance. Philosophy is highly logical, and uses specific language (or symbolic representations), so is of particular interest to any SEI who spends a long enough time thinking... which is most of absolutely anyone of any type with enough intelligence.
Also, considering the preponderance of Alpha NTs in philosophy, it's little surprise it attracts Alpha SFs like flies to a dead horse
