I don't think I'm more intelligent than most people, I might have below average intelligence, but I think I'm more 'analytical'. It seems to me that most people don't think deeply about ethical issues, they don't really make any serious attempt to employ unbiased and objective logical reasoning when it comes to their ethical stances or how they justify and rationalize the decisions that they make. Ultimate first principles or starting values might be subjective and arbitrary (I would argue that we experience happiness as intrinsically valuable but I won't get into that because it's probably besides the point) and not 'logically' based in any way but once we have a starting first principle or value logic comes into play when it comes to applying it consistently. Most people base their attitudes and decisions on common sense that you either 'get' or you don't 'get', cultural norms and contradicting intuitions, values and arguments that vary arbitrarily from circumstance to circumstance. They routinely contradict themselves in ways that they don't even realize. I don't mean to sound superior, I'm not and I also contradict myself, but I think I have a much better understanding of what moral consistency implies than the vast majority of people do.
