I'd say if you're not intelligent enough to also develop your emotional or spiritual development (it doesn't have to be forced you just need to not be closed to it), then you aren't really extremely intelligent, you're just trying to come off as one or more accurately your idea of how one would be like.

Last I heard MENSA has an annual fee, isn't that already a nice indicator of the intelligence of its members, to pay for an "I am smart" badge?
