If you had the power to perfectly control what sort of personality types people were born with, what is the optimum mixture of personalities to create?
I don't know the answer to this question but that's because I don't have a superhuman understanding of psychology. I don't see how it poses any moral problems.
With my very limited current layperson's knowledge, in terms of the big 5 I would probably increase Openness and Conscientiousness, leave Agreeableness and Extraversion at current rates, and decrease Neuroticism.
The question I'm trying to frame is, if you have the power to choose what preferences people would have, what would you choose? Obviously you'd increase Conscientiousness and decrease Neuroticism, because they generally determine how good you are at fulfilling your preferences, not what your preferences are. Increasing Openness would probably also be good because it would help prevent people from being jerks to those who are different, and I think that we would desire anyone we create to want to behave morally.
But what kind of preferences would you gi...

On the old old gnxp site site Razib Khan wrote an interesting piece on a failure mode of nerds. This is I think something very important to keep in mind because for better or worse LessWrong is nerdspace. It deals with how the systematizing tendencies coupled with a lack of common sense can lead to troublesome failure modes and identifies some religious fundamentalism as symptomatic of such minds. At the end of both the original article as well as in the text I quote here is a quick list summary of the contents, if you aren't sure about the VOI consider reading that point by point summary first to help you judge it. The introduction provides interesting information very useful in context but isn't absolutely necessary.

Introduction
Nerd Failure Mode
This section is the part most relevant to LessWrong:
In sum:
I bolded the note on mass literacy and participation because of the interesting historical conclusion that in the United Stated mass participation in democracy inevitably made the influence of religion on policy greater. It goes against a deep assumption shared by most educated people that "democratic elections" necessarily produce "liberal" or "secular" results. It was particularly evident among pundits and particularly easy to see as foolish with the recent upheavals in the Middle East.
This last rather minor seeming note is perhaps the most relevant part of the article for aspiring rationalist. Not only is it particularly salient for those us inclined to questioning the usefulness of the category "religion" in certain context, but because nearly all of us are not religious. Our bad axioms seem unlikely to originate directly from something like a religious texts, though obviously it is plausible many of our axioms ultimately originate from such sources.Not many of us are Communists either, but we are attracted to highly consistent ideologies. We seem likely to be particularly vulnerable to bad axioms in a way most minds aren't.
So if after some thought and examination you notice that a widely respected and universally endorsed axiom in your society has clear and hard to deny implications that are in practice ignored or even denounced by most people, you should be more willing to dump such axioms than is comfortable.
