Compared to the current qualities we select for? Breeding among humans is by no means random, and I think selecting for intelligence would be an improvement. I think the bigger concern is how we select for intelligence. Doing it based on a few genes that correlate strongly with intelligence can lead to an increased vulnerability to health issues related to those genes we don't know about, but I think this applies to any gene level selection based on any characteristics.
