They are better at evaluating threat when in a threatening environment and better at inventing it when it's not. A defect is only a defect in the context where it is one. I would like to see the data on better at empathizing, I suspect better at group empathy. I think conservatives give more to charity, all the government social programs that cost far more are liberal inventions, because we all pay taxes so liberals vote to give via self imposed gifting. Conservatives operate on quite a few levels of moral concerns more that liberals do and thus have a broader understanding of others values. A liberal can doesn't get the team loyalty thing, or respect for authority, tradition, custom, or religious laws governing purification via diet or prayer and other things they think are irrelevant. They focus and more so than conservatives on justice and equality. So liberals don't see the conservative breadth of concern as better. So I would say that you have tailored you the reality here to fit a point of view that is self flattering. In short I don't think your data shows what you chose to see in the differences known to exist.
It is a defect, then, say, not to eat pork when pork is all there is to eat. It is a defect to worship private charity when needs rise to levels that private charity can't support. It is a defect when ones loyalty to ones own group leads to demonization of other teams playing in the same league. It is a defect when injustice and inequality rise to levels that are dire and don't get sufficient attention, etc. In short a defect requires context. But the understanding of context can raise problems of cognitive dissonance and where this occurs, it is liberals and not conservatives who will be most objective about what the context really is, that is according to the scientific information.
The real issue them is that while all of know we are imperfect, we still resist that fact in reality and when it comes to the specifics.
