I think all the 16 types has excellent features, we’re talking bout this in 2014.. imagine, this is the result after billion years of living in this planet.
IQ, to me, is one thing from what’s called “Intelligence”.
The Quality of the available affordable IQ tests are very low, so the results are very inaccurate at first place.
ALL the types are well made, ALL the types are intelligent, there’re no type better than other, they’re different but equal in value.
It’s only about variety, which is very good to exist in kinds of beings.
