That is what the thesis says, and it is pretty predominant in certain circles (form what I've seen, it is very common in educational circles). There is also musical, intrapersonal, naturalistic and existential, intelligences. Also it is more than being an extrovert or introvert. A manipulative person can be pretty ontrovert, but understand otehr peoples feelings at a moment (certain characteristics of a psycopath), meaning he has good social intelligence even when being not a very sociable person.Ieyke said:It's a stretch to rename introversion/extroversion and coordination types of intelligence. And even then, some people are clearly smarter than others, if you were to call those things types of intelligence.
The merits of this theory are probably not in the scope of the topic, but it was probably invoked to make OP not feel bad about himself. Even if he isn't that good at logical intelligence than his girlfriend, he is probably smarter in other areas (muscial, kinesthetic, social...) than his girlfirend and therefore he shouldn't feel less than intelligent than her, as he has developed different intelligences.
