The "openness" trait from big five personality research (pretty legit) correlates with IQ. More open people are both more likely to question the status quo and are more likely to be more intelligent (in the strict sense of the word) than average. This suggests but doesn't necessarily mean that anything would come of it.

There's also the question of whether or not the genetic changes they attempt to make would increase intelligence independently of openness, which is likely possible, but that would require a deeper understanding and familiarity with the subject.
